SINGLE-BILL SERVICE OFFER MANUAL

Lead Times & Releases
Steelscape will make every attempt to satisfy the customer order request date. Availability of materials - substrate and paint - in addition to line time availability will determine Steelscape’s ability to meet the request date. Every order will reflect the customer order requested ship date as well as the Steelscape Acknowledged Date.

To help our customers better understand Steelscape’s order entry process as it relates to lead times we offer the following order practices:

Steelscape commits to shipping orders within the agreed lead times.

Steelscape does require orders be processed with a release date already provided or the orders to be released at least  one week prior to the Acknowledged Date. This will enable us to rapidly package the orders, schedule appropriate transportation and have them shipped on or before the date we have indicated.

Steelscape requires 48 hours to arrange trucking. Orders requiring shipment should be released a minimum of 48 hours prior to the required shipping date.

In the absence of a customer order release received at least one week before the Acknowledged Date, Steelscape will produce and package for shipment all orders by the agreed date.

NOTE: Our delivery time is measured by the Acknowledged Production Date of the order and does not include the transportation time or mode used to deliver the product from our facility to the customer’s final destination. Providing a release date when placing an order will help ensure the added time for transportation is minimal.

Order Acknowledgments
Upon receipt and entry of an order into the Steelscape production system, the customer will be provided an Order Acknowledgement. The acknowledgement will contain all specifications related to the order and should be reviewed to ensure accuracy. Any discrepancies must be brought to your Customer Service Representative’s attention immediately.
Order Acknowledgements will be sent for all orders unless requested otherwise in writing from the customer to the ap- propriate Steelscape Customer Service Representative.

Change Requests
We realize sometimes an initial order will need to be altered. Recognizing that potential need, we have established the fol- lowing guidelines to help customers understand our change policy for existing orders.

Any changes to an existing order must be submitted in writing to the Customer Service Representative (CSR).

The CSR will initiate the change in Steelscape’s system by obtaining approval from all appropriate departments, as

determined by the type of change requested. Each request will be reviewed within twenty-four (24) hours. Howev-
er, it may take up to one (1) business day to determine acceptance or refusal of the requested change.

STEELSCAPE TERMS & CONDITIONS OF SALE

STEELSCAPE TERMS & CONDITIONS OF SALE
Acceptance. No terms or conditions other than those stated herein, and no agreement or understanding, oral or written, purporting to modify these terms or conditions, whether contained in Purchaser's purchase order or shipping release forms or elsewhere, shall be binding on STEELSCAPE, LLC ("Seller") unless signed by its authorized representative. No proposals, negotiations and representations, if any, made prior and with reference hereto shall have any effect unless expressed herein. Notwithstanding the above, this order shall be subject to acceptance by Seller. Acknowledgement of an order by Seller does not constitute acceptance of the order unless expressly so stated. Upon acceptance, Seller shall have the right to begin performance. Purchaser shall not have the right to cancel this order after it has been accepted without paying a Cancellation Charge. The amount of the Cancellation Charge shall be based upon costs incurred with respect to the canceled order, as determined by Seller.

Price. (a) The prices in this order are based upon circumstances existing on the date Seller accepted the order. All charges for (and all subsequent increases in or impositions of) insurance, freight or transportation rates, demurrages, storage costs, port charges (wharfages, re-handling, and other charges), customs or import duties, dumping duties and countervailing duties, surcharges, border taxes, governmental tariffs, and any other charges, taxes, duties, assessments, imposts or other levies of any nature whatsoever, imposed by any private, public, governmental or quasi-governmental agency whether national, state or local, foreign or domestic, whether caused by change in duty classifications, valuations or for any other reason whatsoever, shall be added to and become a part of the order price and paid by Purchaser hereunder. (b) Freight and insurance charges from Seller's facility or Seller's supply point and Seller's freight handling charges shall be borne by the Purchaser unless otherwise agreed. The freight and handling charges shown on the invoice may include an additional handling charge and/or may not reflect the actual cost of shipping the goods delivered hereunder.
(c) Purchaser shall pay all applicable sales, purchase, use, consumption and excise taxes. If Purchaser's purchases of the goods are exempt from sales or use tax, Purchaser must furnish the appropriate resale certificates or sales tax exemption numbers. Except as otherwise specifically provided in this order, all import permits and licenses and the payment of all United States import duties and customs fees shall be the sole responsibility of Purchaser. (d) Where metal is supplied by Purchaser, the weight billed is the weight of coated metal shipped. (e) The pre-painted acknowledgement price covers a specific quantity. If less metal is supplied by Purchaser for painting in one production run than quoted, Seller will adjust the order price to the appropriate quantity bracket without notifying Purchaser. (f) Orders are subject to re-pricing upon written notice by Seller to Purchaser.

Payment. (a) Payment shall be made in compliance with Seller's payment terms and such payment shall not be subject to retainage of any description. Seller may suspend production, shipments, and delivery and retake possession of any materials furnished until all such payments as are due are paid in full. All payments not made when due shall bear interest at the rate of 18% per annum from the due date (or the maximum interest rate allowed by the state in which the sale is made whichever is less). If suit is brought by Seller to enforce this agreement, Purchaser shall pay a reasonable attorney's fee to Seller as fixed by the Court, plus other reasonable costs of collection. Failure to pay invoices when due shall make all other outstanding invoices immediately due and payable. The receipt by Seller of part payment of the full amount then due and payable shall not be a waiver of any of Seller's rights set forth herein or provided by law. (b) If, in the sole judgment of Seller, it appears that Purchaser may not be able to make payment when due, or if Purchaser otherwise has not made payment to Seller as required under a different order, Seller shall have the right to suspend manufacture, shipment, or delivery of materials and seek reasonable assurances of Purchaser's ability to make payments. Seller shall resume suspended performance at the time that in its sole judgment adequate assurances have been provided. (c) All deliveries shall be subject to the approval of Seller's Credit Department. Seller reserves the right before making any delivery to require payment in cash or additional security for payment; and if Purchaser fails to comply with such requirements, Seller may terminate this order

Shipment and Claims. (a) Unless otherwise specified in writing, Seller's delivery obligation shall be at Seller's facility. The goods shall be made available to Purchaser for receipt at Seller's facility during normal business hours after notification is given to Purchaser by Seller that the goods are ready for pick up. Where warehouse storage is provided by Seller for Purchaser's goods, Seller is not liable for any metal deterioration. (b) All shipping dates are estimates and are based upon prompt receipt by Seller of all information necessary for completion of the order and are subject to delays should Seller suspend production, shipments and delivery pursuant to Sections 3(a) or (b) above, or otherwise. (c) Seller shall not be liable, and Purchaser agrees to forego making claims against Seller, for delays in manufacture,
shipping, or delivery caused in whole or in part by: delays in receipt of or unavailability of materials, fuel, power or transportation; breakdown of equipment; strikes, lockouts or other differences with employees; local labor shortages; accidents, war, riots, fire, floods, storms, epidemic, acts of God or other casualties; acts of the Purchaser; government action, embargo, allocation, regulation or requirement; any act or neglect of the carrier or any other person not employed by Seller, including without limitation subcontractors, manufacturers, or suppliers of Seller; or other causes beyond Seller's reasonable control whether of a similar or dissimilar nature than those enumerated. (d) If Purchaser does not schedule pick up or unloading at the delivery site within a reasonable time, Seller may assess the costs of delay and shall not be responsible for any additional costs incurred as a result of such a delay. In addition, if, for any reason, this order is placed on ship hold, (i) Seller shall not be responsible for defects in the primer or finish coat of paint that may be caused by weather conditions, (ii) the order will be subject to storage charges as billed by Seller, and (iii) Purchaser shall be responsible to make payment for such materials. (e) Purchaser shall accept or reject the goods by written notice to Seller given promptly upon delivery of the goods. All claims of any kind or nature must be made within 48 hours of receipt by Purchaser of the goods. Purchaser is familiar with the nature of the goods furnished by Seller and agrees that the time period set forth herein for notice of nonconformity is reasonable. All claims must be supported by coil identification and must be in its original size unless otherwise agreed to by Seller. Seller reserves the right to inspect such material upon notification from Purchaser. Inspection and testing by Seller is final and conclusive and shall be binding upon Purchaser. No returns will be accepted or allowances made unless authorized in writing by Seller. Seller shall have satisfactorily performed its obligations hereunder if it supplies an amount with ten percent (10%) more or less than the amount ordered unless otherwise specified. (f) Seller shall not be responsible for spoilage caused by defective metal supplied by Purchaser whether such spoilage occurs at Seller's plant or at Purchaser's plant. Similarly, Seller will not be responsible for deviations in the physical dimensions of Purchaser's material. Although it is the policy of Seller to advise Purchaser should Seller determine that any of Purchaser's material is not suitable for coating, if Seller for any reason runs a portion of Purchaser's material before a defect is detected, Purchaser agrees to pay to Seller for Seller's time and the coatings used. (g) Purchaser acknowledges that the production of pre-painted metal on high-speed coil coating lines and other production equipment has hazards which are caused by imperfections in metal as well as technical problems associated with continuous high-speed coil coating. Purchaser agrees to absorb, without claim, up to three percent (3%) of the coating material shipped per order. (h) Purchaser acknowledges that the inside and outside laps of coils may have a defective finish due to necessary handling and that there may be test marks necessary to maintain quality in each coil. Purchaser agrees that neither of these conditions are cause for rejection.

Risk of Loss, Title, and Security Interest. Risk of loss and title for the goods shall pass to Purchaser, subject to any applicable lien rights of Seller at the time of shipment to Purchaser of the goods. Purchaser must obtain adequate insurance to cover the goods from the time of risk of loss has passed from Seller. To the extent this order is for Seller to provide metal painting service only, Purchaser hereby grants to Seller a security interest in the goods as described more particularly elsewhere in this order, in all accounts, chattel paper, general intangibles, documents, instruments and causes of action related thereto, and in all proceeds of all of the foregoing in order to secure Purchaser's timely payment of the purchase price hereunder. Cumulative with all other remedies available to Seller in law, at equity, or otherwise, Seller (a) may require Purchaser to assemble the collateral and make it available to Seller at a place designated by it which is reasonably convenient to both parties; (b) shall be entitled to recover all reasonable legal fees and costs incurred by it; and (c) shall have the right to notify customers, account debtors or other obligors of Purchaser that Seller has been granted a security interest in Purchaser's accounts, and to collect such accounts directly. Any notification under this paragraph to Purchaser's customers, account debtors or other obligors by Seller shall constitute and be deemed for all purposes and instruction by Purchaser to said cust omers, account debtors or other obligors to make payment directly to Seller. In any case where such instruction by Purchaser may be required, Purchaser hereby irrevocably makes, constitutes and appoints Seller and its officers and employees as its true and lawful attorneys in fact, with power to endorse Purchaser's name

upon checks, notes, account drafts and other instruments and evidences of payment that may come into Seller's possession in connection herewith. Amounts collected by Seller directly from Purchaser's customers, account debtors or other obligors after notification hereunder shall be applied against the secured obligations. Purchaser shall remain liable for any deficiency remaining unpaid after such application.

Warranty. Seller warrants that Seller's goods will comply with the coating manufacturers specifications set out in this order. If this order is for metal painting, Seller warrants that the painted metal will meet the specifications set out in this order and that the coating system and method of application of the coating system will be adequate within established tolerances. Purchaser shall assume all risk and liability resulting from the use of the goods, including the use of the goods in manufacturing, construction, or processing, and the use of the goods in combination with other materials or substances. If goods sold hereunder are not as warranted, Seller shall, at its option, refund the purchase price for the nonconforming component, or repair or replace such goods provided Purchaser has given timely written notice of the nonconformity and has given Seller an opportunity to investigate. Seller shall incur no liability for damage, shortages, or other cause alleged to have occurred or existed at or prior to delivery to the carrier unless Purchaser shall have entered full details thereof on its receipt to the carrier and given Seller timely written notice of said nonconformity as detailed above. This warranty shall not apply to goods that have been subject to mishandling, misuse, neglect, improper assembly, alteration, or repair by Purchaser or the customer of the Purchaser. The goods sold hereunder shall be subject to Seller's standard manufacturing variations, tolerances and classifications which are published by Seller and will be made available to Purchaser upon request. All painted materials shall be sold subject to tolerances recognized by industry standards. EXCEPT FOR THE FOREGOING EXPRESS WARRANTY, THERE ARE NO OTHER WARRANTIES, WHETHER ORAL OR IN WRITING OR WHETHER EXPRESSED OR IMPLIED BY OPERATION OF LAW OR OTHERWISE, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR ANY IMPLIED WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.

 LIMITATION OF LIABILITY. IN THE EVENT OF SELLER'S LIABILITY ARISING FROM CLAIMS RELATING TO THE DESIGN, SALE, HANDLING OR USE OF GOODS PURCHASED HEREUNDER AND WHETHER BASED ON CONTRACT, TORT (INCLUDING BUT NOT LIMITED TO NEGLIGENCE AND STRICT LIABILITY) OR OTHERWISE, SUCH LIABILITY WILL BE LIMITED TO $25,000.00 OR THE PURCHASE PRICE OF THE SPECIFIC NONCONFORMING COMPONENT(S), WHICHEVER AMOUNT IS GREATER. NOTWITHSTANDING ANY STATEMENTS CONTAINED HEREIN TO THE CONTRARY, IN NO EVENT SHALL SELLER BE LIABLE FOR ANY CONSEQUENTIAL OR INCIDENTAL DAMAGES (INCLUDING, WITHOUT LIMITATION, ANY CLAIM FOR DELAY, LOSS OF EFFICIENCY, IMPACT, LOSS OF PRODUCTION OR ANTICIPATED PROFITS) OR LIABILITY INCURRED BY PURCHASER WITH RESPECT TO ANY GOODS OR SERVICES FURNISHED OR TO BE FURNISHED HEREUNDER BY SELLER. IN NO EVENT, REGARDLESS OF THE LEGAL THEORY ON WHICH A REMEDY IS SOUGHT, SHALL SELLER'S LIABILITY EXCEED THE PURCHASE PRICE OF THE GOODS IN QUESTION. IN THE EVENT PURCHASER DESIRES SELLER TO ASSUME GREATER LIABILITY FOR THE PURCHASED GOODS, A CHOICE IS HEREBY GIVEN OF OBTAINING FULL OR LIMITED LIABILITY BY PAYING AN ADDITIONAL NEGOTIATED AMOUNT PROPORTIONED TO THE RESPONSIBILITY, AND AN ADDITIONAL WRITTEN RIDER SHALL BE ATTACHED TO THIS AGREEMENT SETTING FORTH THE ADDITIONAL LIABILITY OF SELLER AND THE ADDITIONAL CHARGE. THIS CHARGE IS NOT TO BE CONSIDERED AS BEING A CHARGE FOR INSURANCE OF ANY TYPE, BUT IS INCREASED CONSIDERATION FOR THE GREATER LIABILITY INVOLVED.

 Indemnification. Purchaser agrees to indemnify, defend, and hold harmless, Seller, its affiliates, and their officers, directors, employees and representatives from and against any and all claims and liability for injuries or loss to persons or property, or fines, or other damages, including all costs, expenses, legal and otherwise, arising from or relating to in whole or in part the goods sold hereunder, any use or possession of the goods sold hereunder, or any fraud, misrepresentation, negligent act, negligent failure to act (including the failure to properly store or handle material), gross negligence, or violation of statute or government regulation, by the Purchaser.

Limitation Period. No claim, cause of action, or suit relating to this order shall be brought by Purchaser against Seller after the expiration of one year from the date of delivery of materials. This provision shall not be construed reciprocally against Seller in any action or suit brought by Seller against Purchaser.

Severance, Assignment, No Agency Relationship and No Third Party Beneficiaries. In the event that any provision of these terms and conditions shall be deemed illegal, unenforceable, or null and void, all remaining provisions shall remain in full force and effect. Purchaser may not assign its rights or interest or delegate its duties under this order without the prior written consent of Seller. It is understood that Purchaser is an independent contractor and that no agency relationship at law or in fact exists between Purchaser and Seller. It is further understood that neither Seller nor Purchaser intend for this order to benefit any third party or class of persons and there are no intended third party beneficiaries to this order.

Non-Waiver. If at any time during its performance of its obligations under this purchase order Seller fails to assert any rights or remedies available under the terms of this order, or waiver of the rights or remedies available to a party by a course of dealing or otherwise, Seller's failure shall not be deemed to be a waiver of Seller's ability to assert those rights or remedies at any other time during its performance under this order and shall not be deemed to be a waiver of any other right or remedy under this order. Seller's remedies shall all be cumulative and in addition to any other or further remedies available in law, at equity or otherwise.

Applicable Law. The construction, interpretation and performance of this order and all transactions hereunder shall be governed by the laws of the State of Washington without regard to its choice of law principles.

(g) Purchaser acknowledges that the production of pre-painted metal on high-speed coil coating lines and other production equipment has hazards which are caused by imperfections in metal as well as technical problems associated with continuous high-speed coil coating. Purchaser agrees to absorb, without claim, up to three percent (3%) of the coating material shipped per order. (h) Purchaser acknowledges that the inside and outside laps of coils may have a defective finish due to necessary handling and that there may be test marks necessary to maintain quality in each coil. Purchaser agrees that neither of these conditions are cause for rejection.

Risk of Loss, Title, and Security Interest. Risk of loss and title for the goods shall pass to Purchaser, subject to any applicable lien rights of Seller at the time of shipment to Purchaser of the goods. Purchaser must obtain adequate insurance to cover the goods from the time of risk of loss has passed from Seller. To the extent this order is for Seller to provide metal painting service only, Purchaser hereby grants to Seller a security interest in the goods as described more particularly elsewhere in this order, in all accounts, chattel paper, general intangibles, documents, instruments and causes of action related thereto, and in all proceeds of all of the foregoing in order to secure Purchaser's timely payment of the purchase price hereunder. Cumulative with all other remedies available to Seller in law, at equity, or otherwise, Seller (a) may require Purchaser to assemble the collateral and make it available to Seller at a place designated by it which is reasonably convenient to both parties; (b) shall be entitled to recover all reasonable legal fees and costs incurred by it; and (c) shall have the right to notify customers, account debtors or other obligors of Purchaser that Seller has been granted a security interest in Purchaser's accounts, and to collect such accounts directly. Any notification under this paragraph to Purchaser's customers, account debtors or other obligors by Seller shall constitute and be deemed for all purposes and instruction by Purchaser to said customers, account debtors or other obligors to make payment directly to Seller. In any case where such instruction by Purchaser may be required, Purchaser hereby irrevocably makes, constitutes and appoints Seller and its officers and employees as its true and lawful attorneys in fact, with power to endorse Purchaser's name

 LIMITATION OF LIABILITY. IN THE EVENT OF SELLER'S LIABILITY ARISING FROM CLAIMS RELATING TO THE DESIGN, SALE, HANDLING OR USE OF GOODS PURCHASED HEREUNDER AND WHETHER BASED ON CONTRACT, TORT (INCLUDING BUT NOT LIMITED TO NEGLIGENCE AND STRICT LIABILITY) OR OTHERWISE, SUCH LIABILITY WILL BE LIMITED TO $25,000.00 OR THE PURCHASE PRICE OF THE SPECIFIC NONCONFORMING COMPONENT(S), WHICHEVER AMOUNT IS GREATER. NOTWITHSTANDING ANY STATEMENTS CONTAINED HEREIN TO THE CONTRARY, IN NO EVENT SHALL SELLER BE LIABLE FOR ANY CONSEQUENTIAL OR INCIDENTAL DAMAGES (INCLUDING, WITHOUT LIMITATION, ANY CLAIM FOR DELAY, LOSS OF EFFICIENCY, IMPACT, LOSS OF PRODUCTION OR ANTICIPATED PROFITS) OR LIABILITY INCURRED BY PURCHASER WITH RESPECT TO ANY GOODS OR SERVICES FURNISHED OR TO BE FURNISHED HEREUNDER BY SELLER. IN NO EVENT, REGARDLESS OF THE LEGAL THEORY ON WHICH A REMEDY IS SOUGHT, SHALL SELLER'S LIABILITY EXCEED THE PURCHASE PRICE OF THE GOODS IN QUESTION. IN THE EVENT PURCHASER DESIRES SELLER TO ASSUME GREATER LIABILITY FOR THE PURCHASED GOODS, A CHOICE IS HEREBY GIVEN OF OBTAINING FULL OR LIMITED LIABILITY BY PAYING AN ADDITIONAL NEGOTIATED AMOUNT PROPORTIONED TO THE RESPONSIBILITY, AND AN ADDITIONAL WRITTEN RIDER SHALL BE ATTACHED TO THIS AGREEMENT SETTING FORTH THE ADDITIONAL LIABILITY OF SELLER AND THE ADDITIONAL CHARGE. THIS CHARGE IS NOT TO BE CONSIDERED AS BEING A CHARGE FOR INSURANCE OF ANY TYPE, BUT IS INCREASED CONSIDERATION FOR THE GREATER LIABILITY INVOLVED.

 Indemnification. Purchaser agrees to indemnify, defend, and hold harmless, Seller, its affiliates, and their officers, directors, employees and representatives from and against any and all claims and liability for injuries or loss to persons or property, or fines, or other damages, including all costs, expenses, legal and otherwise, arising from or relating to in whole or in part the goods sold hereunder, any use or possession of the goods sold hereunder, or any fraud, misrepresentation, negligent act, negligent failure to act (including the failure to properly store or handle material), gross negligence, or violation of statute or government regulation, by the Purchaser.

Limitation Period. No claim, cause of action, or suit relating to this order shall be brought by Purchaser against Seller after the expiration of one year from the date of delivery of materials. This provision shall not be construed reciprocally against Seller in any action or suit brought by Seller against Purchaser.

Purchaser may not assign its rights or interest or delegate its duties under this order without the prior written consent of Seller. It is understood that Purchaser is an independent contractor and that no agency relationship at law or in fact exists between Purchaser and Seller. It is further understood that neither Seller nor Purchaser intend for this order to benefit any third party or class of persons and there are no intended third party beneficiaries to this order.

Non-Waiver. If at any time during its performance of its obligations under this purchase order Seller fails to assert any rights or remedies available under the terms of this order, or waiver of the rights or remedies available to a party by a course of dealing or otherwise, Seller's failure shall not be deemed to be a waiver of Seller's ability to assert those rights or remedies at any other time during its performance under this order and shall not be deemed to be a waiver of any other right or remedy under this order. Seller's remedies shall all be cumulative and in addition to any other or further remedies available in law, at equity or otherwise.

Applicable Law. The construction, interpretation and performance of this order and all transactions hereunder shall be governed by the laws of the State of Washington without regard to its choice of law principles.

Certain chromium and nickel compounds as well as organic compounds found in various coating materials have been listed as carcinogens by the NTP, IARC, or OSHA.
Medical Conditions Aggravated by Long Term Exposure:
Individuals with chronic respiratory disorders (i.e., asthma, chronic bronchitis, emphysema, etc.) may be adversely affected by any fume or airborne particulate matter exposure.
Chronic Effects:
Chronic inhalation concentrations of iron oxide fumes or dusts may lead to a benign pneumoconiosis (siderosis). Inhalation of high concentrations of ferric oxide may possibly enhance the risk of lung cancer development in workers exposed to pulmonary carcinogens. Chronic inhalation concentrations of aluminum fumes or dusts may lead to a fibrotic lung condition known as Shaver.s disease; however, evidence for this is not conclusive since affected workers were exposed to other substances (silica) as well. The inhalation of high concentrations of dust from manganese, copper, lead and/or zinc in the respirable particle size range can cause an influenza-
like illness termed metal fume fever. Typical symptoms last 12 to 48 hours and are characterized by metallic taste in mouth, dryness and irritation of the throat, followed by weakness, muscle pain, fever and chills. Continuous exposures to high concentrations of manganese can cause central nervous system disorders and .manganese pneumonia.. Fibrosis of lung tissue from manganese exposure has also been reported for products containing manganese only. Overexposure to aluminum dust can cause shortness of breath. Long term inhalation exposure to high concentrations (overexposure) to pneumoconiotic agents may act synergistically with inhalation of oxides, fumes or dusts of this product to cause toxic effects. Prolonged or repeated contact with

unprotected skin may result in skin irritation. Torching or burning operations on steel products with oil or organic coating may produce emissions which can be irritating to the eyes and respiratory tract.
Precautionary Statement:
Inhalation of metal dust and fume may result from further processing by the user, particularly during welding, burning, grinding and machining activities. These potential health hazards should be evaluated by the user.

TECHNICAL BULLETIN

General Guide to Good Practice in the Use of ZINCALUME® Steel for Roofing and Siding Products

INTRODUCTION
Panels fabricated from ZINCALUME® Steel will provide many years of trouble-free service when properly designed, installed and maintained. The key to obtaining all of the benefits of the corrosion resistant coatings applied to steel used in roofing, siding and rainwater items lies in correct material selection,
good handling and installation practice, and sensible maintenance.

Few roofing or siding products are replaced because of an overall breakdown or general corrosion.
Replacement is generally due to isolated component failure which could have been avoided by following a few simple rules. This Technical Bulletin sets out the general principles to follow. Attention to the following factors should ensure satisfactory performance
and good service life. Manufacturers’ specific recommendations about their particular products should be followed.
Correct Selection of Materials
The correct selection of roofing and siding materials is the first step to ensuring a building’s long life. The range of products manufactured by Steelscape is designed to provide good performance under normal environments from benign rural areas to corrosive industrial or salt-laden coastal atmospheres. Correct selection is a matter of choosing the right product for its intended use.

A roofing installation in a coastal environment has a completely different demand upon it than one in a benign rural location. Our experienced sales and technical personnel should be consulted if there is
any doubt as to the correct metallic coated or painted

product for a specific structure. This is especially true for the special requirements of severe coastal
and industrial as well as animal confinement environments.
Designs for Durability
There are many factors that should be considered in the design phase of any building to ensure the
maximum trouble-free service life. The following factors are some of the primary considerations.

Minimum Roof Pitch
The pitch must be designated/designed so that standing water conditions are not created. Water or condensate must freely drain from the roof panels. Where a roof includes several slopes, a valley gutter or other device should be installed to ensure adequate drainage. Specified minimum pitch will vary according to the depth of the roof profile and the means of fastening. Many standing seam roofing systems with deep profiles (i.e. panel seams ranging from 2-3 inches), fastened with concealed clips which do not penetrate the steel weathering membrane, may be installed down to a minimum slope.

Regardless of roof pitch, the cut ends of panels should be burr down, or designed with a rolled, or hemmed edge to prevent moisture from being held at the edge.

A properly installed standing seam roofing system will allow the roof to drain effectively without “flooding” the laps. The concealed clips ensure the drainage part of the panel membrane is not breached by fastening holes through which water may leak. Perimeter detailing and flashing is also an important component of such a system.

A roof fixed to its minimum pitch must observe all of the criteria for correct installation. Supports must be carefully aligned to avoid creating low spots in the roof where ponding will occur, leading ultimately to reduce service life.

Correct Support Spacing
Correct spacing of supports is important. Not only do the purlins, battens, etc., support the weight of the roof and the weight of the roofer during installation, they must be strong enough to prevent the sheets of decking from blowing away in high winds.

Support spacing near the eaves and the ridge is usually less than the intermediate spacings. This allows the roof to handle the increased lift and forces created by wind turbulence. The supports hold the roof down and they must themselves be restrained. It is possible for a roof to be blown off with the purlins or pieces of poor quality lumber battens attached to the sheets.

Steel Thickness - Base Metal
To protect steel sheet from the corrosive effects of the elements, a layer of metallic aluminum/zinc alloy is applied to the steel base in the hot-dip process. To enhance this protection as well as provide an attractive appearance, a pre-painted steel finish is also an option. These protective finishes are the major determinants of long service life and lasting good looks. The structural strength of the roofing or siding profile is derived entirely from the steel base and the profile of the particular steel panel.

An important consideration in the spanning capacity of a steel profile is its base metal thickness, which is used to determine support spacings. The total thickness of pre-painted steel sheet (the base metal steel plus an aluminum/zinc hot-dipped coating, plus pre-painted finish) is, at best, a very imprecise indicator of the base metal thickness which provides the strength of the roof sheeting.

The ability of the roof sheeting to span recommended distances without severe deflection, to support the installer, and to resist tearing away from fixing clips or screws largely depends on the base metal strength.
Always ensure that the base metal thickness specified

is according to recommendations. Most metal panel manufacturers provide load tables to assist in the selection of an appropriate profile for spanning conditions.

Fume Extractors & Vents
Corrosive dust and particles can be released through roof vents and discharged onto the roof surface. The immediate area of the roof adjacent to the vent is then at increased risk of corrosion. The following design guidelines should be considered to avoid problems.

Locate vents on the corner of the windward side of the building.
Install filter elements to trap hazardous material.
Specify pre-painted product or apply a protective coating to the affected area of the roof.
Maintain coal or oil fired boilers or incinerators so they do not discharge sulfur compounds over the roof surface.
Avoid condensate from copper tubing.

Foot Traffic
Repeated foot traffic and the dragging of maintenance or cleaning equipment over the roof surface may damage the roof which will reduce its life expectancy. Catwalks and platforms should be designed and installed where necessary.

Roof Structures
Equipment such as air conditioning units are often se- cured to uncoated steel channels. Uncoated steel used on a ZINCALUME Steel roof should be cleaned, primed and given a suitable finish coating. If left unprotected the rust may bleed onto the ZINCALUME Steel panels and stain the surface. For guidelines on the instal- lation of photovoltaic panels see Technical Bulletin #12 “Guidelines for the Use of Photovoltaic Panels with ZINCALUME® Steel”.
Site Storage Before Erection
Where possible do not leave uncovered coils or stacks of sheets lying in the open. Install finished material as quickly as possible. Store materials indoors and away from openings to the outside. On arrival at site, ensure the steel sheets are dry. If wet, open the pack

immediately, separate the sheets and allow them to dry.

If it is absolutely necessary to store ZINCALUME Steel outdoors please follow the following guidelines:

Erect simple scaffolding around the material and cover it with a waterproof sheet or tarp. Ensure space is allowed between the cover and the material to allow air to circulate.
Store material off the ground and on an incline so that if rain should penetrate the covering, water will drain away.
Use only dry, untreated lumber spacers for block stacking.
The storage site should be inspected regularly to ensure moisture has not penetrated the stack. If moisture has gotten between panels they should be separated and dried immediately. ZINCALUME Steel must not come in contact with wet cement or concrete. If contact occurs remove immediately.

INSTALLATION GUIDELINES
Allowance for Expansion
All roofing and cladding will expand and contract with changes in temperature. Fastening/Fastener attachment systems used must accommodate the expansion to avoid problems of “canning”, ponding or
roof noise. Expansion tables are usually available from the panel manufacturer.

Handling
Handle panels carefully. Do not drag or slide sheets over other products or rough surfaces. Equipment and materials placed on to the roof should be clean and care taken to prevent damage to the surface.

Long panels are best lifted with the aid of a lifting boom. Flat, rubber soled footwear should be worn when walking on a roof. Shoes should be cleaned before going up on the roof.

Bare ZINCALUME Steel is prone to fingerprinting and hand printing. ZINCALUME Plus Steel, which has a clear acrylic resin applied, is recommended for unpainted applications. The clear resin prevents

finger and hand prints and aids in forming. If bare ZINCALUME Steel is utilized, clean gloves should be worn when handling.

Laying
Pierced sheets should be installed with overlaps away from the weather. End laps in profiled metal roofing should be avoided where possible. The end lap of ZINCALUME Steel and painted profiles should be sealed with a double bead of sealant.

Marking, Cutting & Drilling
Black lead pencils should never be used for marking ZINCALUME Steel products as the carbon in the pencil will promote corrosion which will etch the surface leaving a permanent mark. Use any other color pencil but black. Cut and drill pre-painted steel with care to avoid marking the high-quality surface. Use a hand shear or nibbler instead of a friction blade to avoid damaging the ZINCALUME Steel or paint coating.
Remove all debris and metal filings as soon as possible.

Fasteners - Placement, Size, Type, Life Expectancy & Compatibility
The security of a roof is no better than its fasteners. Correct choice and placement ensures fasteners are placed in effective positions. The use of nails is not advised for roofing and siding profiles. Screw type fasteners with washers are recommended and have been proven to have 2 to 3 times the holding power of nails. Care should be taken not to under-drive, or over-drive screws. Large washers are necessary
when hurricane conditions apply to the location. This prevents screws being pulled through sheeting under high lift forces.

Fasteners used for external fixing of roofing and siding products must be compatible with
ZINCALUME Steel and have a life expectancy comparable with the ZINCALUME Steel panel.

Our recommendations on type and compatibility of fasteners are published in Technical Bulletin #3
“Fastener Selection for ZINCALUME Steel Roof & Siding Products”.

There are some fasteners on the market with only minimal corrosion protection. These will quickly rust

and present an unsightly appearance. Fasteners made of some alloy materials are highly corrosion resistant in their own right but a galvanic couple may occur when they are in contact with ZINCALUME Steel. This may cause an increased rate of corrosion of the steel around the fasteners. Screw manufacturers/suppliers should be consulted to ensure correct usage.

Clean-up
After erection has been completed the roof panels and gutters should be swept to remove dirt and debris such as unused fasteners, metal filings, pop-rivet stems, and pieces of flashing. The shank of a fastener left lying on a roof will rust very quickly and will run down onto the panel causing an unsightly stain. The process of cut- ting roof and wall sheeting to size with discs, or drilling to fix with fasteners, can create debris which is un- sightly and can create localized corrosion and shorten the service life. Technical Bulletin #4 “Prevention of Damage to Steel Roof & Siding Products from Metal Filings” covers this in greater detail.

Mud and dirt tracked onto the roof panels, and greasy hand and footprints, can be removed by washing with a cleaner consisting of 1/3 cup mild detergent in one gallon of water applied with a mop or soft broom.
The roof should then be thoroughly rinsed with water. High pressure spray applications and strong alkaline detergents should not be used. If washing with a detergent solution is found to be inadequate, solvents such as mineral spirits can be used to remove more stubborn stains. More aggressive and highly volatile solvents such as acetone or toluene should be avoided for safety reasons, as well as their incompatibility with many paint systems used on building panels. The compatibility of any solvent on paint should be tested or known prior to its use. Tri-sodium phosphate (TSP) cleaners should not be used.

Compatibility of Accessories Including Flashing & Sealants
There are basic facts regarding compatibility of metal products that are usually predictable and well docu- mented. These have been summarized into a few sim- ple rules for roof installers in Technical Bulletin #2 “Flashing Materials for Bare & Pre-painted ZINCALUME Steel” which cov- ers this topic in much more detail. The mix of incom- patible metals or materials with dissimilar service life is poor practice and will significantly affect service life. Correct choice of sealants to suit materials and loca- tion is important. Sealants containing amine or acidic acid should never be used. High quality sealants, such as neutral cure silicones, provide good performance
in most applications. They may cost a little extra but are a good investment. Recommendations on sealant selection are covered in Technical Bulletin #5 “Sealants for ZINCALUME Steel.”

Flashing Materials for Bare & Pre-painted ZINCALUME® Steel

INTRODUCTION
The preferred flashing material for ZINCALUME® Steel is either bare or painted ZINCALUME Steel. The
following guidelines have been provided to assist in the informed use of other materials where necessary.
COMPATIBILITY
Galvanic Corrosion
Due to a phenomenon known as galvanic or bi-metallic corrosion, some commonly used metals can cause accel- erated corrosion when used with ZINCALUME Steel zinc/ aluminum alloy-coated and pre- painted sheet. The field of corrosion study has defined an “activity” scale shown in Table 1 which shows zinc and aluminum more active than copper, lead or stainless steel. The farther apart on the scale, the more dissimilar and the stronger the po- tential for reaction between the metals. When a galvanic “couple” is formed by electrical contact the more active metal will sacrifice itself (or dissolve) to protect the less active component of the couple.

ZINCALUME Steel will experience accelerated corrosion when in contact with copper (including copper treated lumber) or lead. Leaching from copper will result in especially high levels of corrosion. The protective oxide film which naturally forms on aluminum surfaces is broken down by copper or lead in localized areas. Pitting corrosion ensues which is a highly accelerated form of attack. Zinc coatings are not generally subject to pitting when in contact with the same materials.

Rainwater Runoff
The galvanic scale in Table 1 is also important when considering runoff from one material to another. If any two of these materials are in damp contact or a runoff situation, the metal higher on the table will sacrifice

itself to protect the lower. A simple guideline to follow is to remember that water can flow downhill but not uphill. Zinc to copper is acceptable but copper to zinc is not.

Catchment (Caution When Combining Different Roofing Systems)
Care should be taken when combining products on a roof system. If products are combined incorrectly se- vere localized corrosion may occur as a result of “inert catchment.”

The zinc coating on galvanized steel products develops a protective surface film as a result of natural weathering. This provides the longevity of performance which is typ- ically known of galvanized products. When flowing over galvanized roofing rainwater dissolves small amounts of minerals and salts from the zinc surface. These minerals and salts promote and maintain the protective film and enhance the corrosion resistance of other galvanized steel products such as gutters and valleys.

When rainwater flows over or is collected from roofing materials which do not promote this protective film (inert materials) accelerated corrosion of unpainted galvanized steel roofs and gutters can occur. Examples of inert materials include ZINCALUME Steel, pre-painted steel, acrylic, glazed tiles, aluminum, fiberglass and PVC.

Unpainted galvanized steel must not be used for roofing or rainwater goods (including valleys and gutters) to collect water runoff from ZINCALUME Steel or any other inert material.

ZINCALUME Steel and painted ZINCALUME Steel can be used to collect water from galvanized or

any inert catchment material. ZINCALUME Steel gutters will typically give a longer service life than traditional galvanized steel.

Standing Water
New applications for standing seam metal roofing have required roof slopes be minimized to as low as 1/4:12.
An area of a roof can be almost flat depending on the particular building. These conditions can create
areas where water can collect and remain for extended periods of time with possibility of accelerated corro- sion. Where an unfavorable galvanic couple exists, the presence of standing water for prolonged periods will allow the corrosion reaction to continue for a longer time than it normally would. In cases where an adverse couple does not exist, enough water can complete the necessary electrical contact and corrosion will proceed as long as the water maintains the circuit.

The appearance of roofing panels can suffer even when all materials within a water-ponding area are compatible. Aluminum-coated steel panels are not as resistant to standing water as ZINCALUME Steel. When the aluminum-coated panel begins to rust, the standing water can disperse and deposit rust parti- cles on an adjacent ZINCALUME Steel sheet panel, resulting in an unsightly stain.

COMPATIBILITY of COMMONLY USED FLASHING MATERIALS
Copper
Copper is incompatible with both bare and pre-paint- ed ZINCALUME Steel, either in contact with or where water can flow from it, such as is often experienced with hot water system overflows. Painting the outside of the copper pipe is recommended. ZINCALUME

Steel must should not come in either direct contact with or water runoff from copper treated lumber. Hot water discharge pipes should be extended beyond the roof, preferably to ground. Every effort must be made to prevent the overflow of water from copper pipes onto the roof and gutter material.

Lead
Lead is the only metal generally considered to be compatible with zinc-coated steel but not with bare or pre-painted ZINCALUME Steel. ZINCALUME Steel, in contact with or receiving run-off water from lead is prone to corrosion. In the event of roof retrofit where lead already exists and its re-use is desirable, the ZINCALUME Steel must be insulated from the lead
by a suitable barrier. This can be achieved by painting the underside of the lead or preferably both surfaces to ensure complete electrical separation. Plastic film can also be used provided it is robust enough and will not tear, e.g., polyethylene damp course placed between the lead and ZINCALUME Steel sheet (with paint on top), is a better alternative.

Lead in the water run-off should be avoided by painting the top surface of the lead flashing. The lead supplier should be contacted for advice as to a suitable finish coat barrier system and the ongoing maintenance re- quirements. Applying two or three coats of water-based acrylic is generally suitable but any painting must be maintained so it will not break down and expose any of the lead surfaces.

Galvanized Steel
Galvanized flashing materials and accessories may be used with bare and pre-painted ZINCALUME Steel.
However, galvanized products may have a shorter life span and thus eventually makes them impractical in the long term. Conditions detailed above with unpaint- ed galvanized subject to water runoff from ZINCALUME Steel panels should be avoided.

Aluminum Coated Type II
Flashings fabricated from this material may be used although inferior resistance of aluminum coated steel to standing water and cut edge corrosion may result in rust staining of adjacent bare and pre-painted ZIN- CALUME Steel.

Graphite
All materials containing graphite should not be used with or adjacent to ZINCALUME Steel. This includes washers and also graphite from pencils used to mark ZINCALUME Steel components.

Stainless Steel
300 series grades are suitable, 400 series grades with
>1.0 mil. zinc or cadmium coating may be used. Other grades should be avoided. Our sales and technical per- sonnel should be consulted where any questions exist.

Fastener Selection for ZINCALUME® Steel Roof & Siding Products

INTRODUCTION
Roofing, siding and accessory products manufactured from ZINCALUME® Steel will give long, trouble-
free service when exposed to the atmosphere in environments ranging from benign to severe in terms of corrosive effect. The selection of the appropriate form of fastener is a task, however, which should not be solely influenced by cost. Fastener costs
are minimal relative to the overall cost of a project and there is little benefit gained through the use of inferior fasteners.

Guidelines for Appropriate Fasteners
The expected service life of the fastener should meet or exceed that of the ZINCALUME Steel components used in the construction. The severity of environ- mental conditions and the corrosion resistance of the fastener should be considered.

The fastener must be compatible with the ZIN- CALUME Steel components. When a more active met- al is placed in direct electrical contact with another less active material the more active component will sacrifice itself to prevent the other from corroding.
This is known as dissimilar metal contact or galvanic corrosion and can be extremely aggressive under cer- tain conditions. Galvanic corrosion can be much faster in corrosive environments such as acid rain due to the increased conductivity of the electrolyte or rainwa-
ter. For this reason lead, copper and copper containing alloys (such as Monel) should not be used in conjunction with ZINCALUME Steel Stainless steel should not be used in severe environments as the ZINCALUME Steel alloy coating can corrode sacrificially. Refer to Table
3 to ensure the fastener of your choice is compatible and has sufficient durability.

Careful consideration should be given not only to the expected performance of the head of the fastener, but the shank as well. This applies particularly if the shank of the fastener could be subject to the effects of aggressive substances, such as acid or chemical fumes or to prolonged humidity and condensation for example, within the confines of a building.

Fastener size, strength and correct fastening pattern are critical and are recommended by the
panel manufacturer.

Guidelines for Installation of Fasteners
Do not overdrive screws or drive at an angle This can result in the washer piercing the steel panel or no longer mating with the area around the hole. The ZINCALUME Steel coating will protect the damaged area for some time; however, rust may prematurely occur depending on how much steel is exposed and on the local environ-
ment. Overdriving a fastener can also cause a depression in the panel which can collect water and create localized ponding. Driving tools equipped with depth sensing nose pieces and suitable RPM speeds can assist in avoiding these problems. Impact type tools should not be used.

Washers - The rubber washer component of self-drilling screws must be manufactured from materials compatible with the roofing material. Washers containing significant levels of conductive carbon black fillers should not be used with ZINCALUME Steel products. The use of carbon or graphite washers may lead to galvanic corrosion, espe- cially in corrosive atmospheres. Black neoprene rubber
is not recommended in any environment as they contain carbon pigmentation which can also cause galvanic corro- sion. Neoprene rubber other than black is acceptable.

Prevention of Damage to ZINCALUME® Steel Roofing & Siding Products from Metal Filings
INTRODUCTION

Steel filings, or swarf, are typically created from cut- ting or piercing operations when using friction saws, abrasive discs, drills etc., on steel roofing and siding products. This debris in addition to other discarded steel objects such as rivet shanks, nails, screws and nuts, which may come in contact with coated prod- ucts; (i.e. pre-painted steel, ZINCALUME® Steel) are the subject of this bulletin.

These particles, if left on the surface, will corrode and cause rust stains which will detract from the finished ap- pearance of a project. These stains are often mistaken for early deterioration of the roofing or siding itself. Preven- tion of such staining is the responsibility of the installer and it is strongly suggested that the recommendations contained in this bulletin be followed.

Metal debris will come in contact with coated steel sheet products in three ways.

Loose particles left after cutting, drilling and riveting operations.
Hot metal filings from disc cutting or drilling operations which may adhere to the finished surface.
Loose particles which may be ground in underfoot or become embedded in the surface film of pre- painted products under pressure from adjacent equipment or materials.

PREVENTION
Cutting
Use of a power saw with a metal cutting steel blade is the best way to cut sheets on site. This method gener- ates larger and cooler particles than abrasive discs.

Where possible, cutting should be minimized by using factory supplied cut-to-length sheets.

Sheets cut on site should, where practical, be cut on the ground, with the exterior color finish of pre- painted sheet facing down. Care should be taken to ensure hot filings do not come into contact with nearby pre-paint steel sheets. Do not cut over the top of other coated products, where debris may fall onto other sheets.
Where cutting must be carried out near sheets already installed, the area around the cut must be covered and the stream of hot particles directed away from complet- ed work. Field cut edges should be concealed under ridge caps or gable flashings whenever possible.

Drilling
The area around the hole should be covered to shield the product from hot metal filings.

Installation
Smooth soled shoes should be worn when working on a roof; avoid the ribbed type which will carry metal filings and other objects.

Clean Up
Metal debris/filings should be swept or hosed from the job progressively and certainly at the end of each day. This action will remove loose particles. Maximum care should be taken when attempting to detach filings which have become stuck; this can be done, but no action which is likely to remove paint or metal coatings should be attempted. Any damage to these coatings will lead to reduced life of the material. When sweep- ing or hosing into a gutter, clean out the gutter before leaving the job in order to prevent premature corrosion.

Note: Many staining problems arise not from installers, but from other contractors working in the vicinity. Architects and builders need to be aware of this possibility and warn contractors accordingly.

On completion of the job give a final wash or sweep down. For critical applications, inspection of the job should be made after two weeks when rain or conden- sation will have caused any remaining filings or debris to rust, and will highlight affected areas.

Identification
Fresh stains are characterized by small red-brown colored areas with a central dark spot (the remains of the steel particles). The surface will feel like sandpa- per, and the particle may be lifted with a fingernail. An old stain will appear as a localized red-brown stain, the steel particle having corroded away, and the surface will be smoother.

Effect on Performance
The effect of staining itself on Steelscape prefinished products is generally aesthetic, and may not be detri- mental to the performance of the product. The product life will be severely affected where attached metal par- ticles have penetrated the pre-painted film and are in contact with the protective metallic coating, although this only occurs in severe cases. This is because on pre-painted surfaces red oxides of iron are normally inert substances and do not attack the finish; the stain is merely absorbed by the finish. Red oxides of iron are insoluble in water and the stain will take considerable time to weather away.

On metallic coatings, concentrated corrosion can occur over a small area as the zinc in the coating sacrifices itself to prevent oxidation of both the debris and, if allowed to continue, exposed areas of the steel base.

Repair of ZINCALUME Steel Sheet
Brush the surface with a stiff bristle (not metallic wire) brush to dislodge particles which must then be com- pletely removed. Wire brushing will mar the appearance of the sheet if brushing is not followed by painting. If the coating is severely damaged by corrosion, the area should be painted. Please contact Steelscape to dis- cuss the correct coating to repair the damaged area.

REPAIR OF PRE-PAINTED SHEET
Mild Staining
A household cream cleanser, used according to direc- tions, will remove most mild staining from metal debris (one cup of mild, common detergent which contain less than 0.5% phosphate, dissolved in warm water are usually effective). Avoid the use of aggressive cleaners such as TSP.

Severe Staining
Clean the surface by washing with a nonionic industrial or household detergent and water in proportions as recommended by the detergent manufacturer. Wash well with clean water.
Remove the corrosion product by using a stiff nylon brush and washing off completely. More heavily affected areas may need a light rub with a Scotch guard tape pad (not steel wool).
Abrasive papers should only be used if repainting is to be carried out.
Great care must be taken not to cause damage to the paint film.
Hose down the affected area completely after treatment.
This treatment will normally leave only very mild stains.

Sealants for ZINCALUME® Steel
INTRODUCTION
This bulletin provides background information relating to sealants and their application when used in conjunction with the range of exterior ZINCALUME® Steel products produced by Steelscape. The sealant industry in the US produces a wide variety of building sealants which togeth- er embrace a multitude of end user applications and an even greater range of specific conditions.

Sealant Selection
The decision on which sealant is the most effective for ZINCALUME Steel products in a specific application should be based on several performance characteristics.

Neutral cure silicone rubber sealants will typically meet the performance characteristics outlined above for most applications. Other generic types of sealant such as polyurethane and butyl elastomers are readily available in tape, hot melt and cartridge forms. Once again the performance of these systems should be evaluated with your sealant supplier based on service condition and performance characteristics. The use of sealants means fastening, whether by integral forming or by individual fasteners is necessary where metal to metal joining is
involved. For more information on fasteners and ZINCALUME Steel, please refer to Technical Bulletin #3, “Fastener Selection for ZINCALUME Steel Roof & Siding Products.”

Physical Property of Sealant	Performance Characteristic	
Adhesion	Good adhesion to bare and pre-painted ZINCALUME Steel, without pre-priming except in extreme service conditions.	
Flexibility	No cracking or loss of adhesion during required bending at specified service temps.	
Weatherability	No cracking, chalking, bleeding or loss of rubber characteristics after exposure to the damaging effects of ultra-violet rays (sunlight) and humidity.	
Water Resistance	Adhesion to metal surface will not deteriorate after immersion in water.	
Chemical Resistance	Good resistance to water, ozone, water vapor, and other chemicals that may be exposed to the sealant in service.	
Non Corrosive*	Will not deteriorate, darken, etch or salt deposit bare or pre-painted ZINCALUME steel.	
Staining	No contact or migratory staining of the bare or pre-painted ZINCALUME steel surface.	
Non Sagging	Will retain original shape within the joint at specified service temperatures w/o sagging.	
Printability	Over paintable if required.	
*Note: Sealants containing acetic acid or amines should not be used on ZINCALUME Steel; wet conditions during early stages of sealant cure can liberate by-products potentially corrosive towards protective coatings. These often smell of vinegar or ammonia.

Cut Edge Protection of ZINCALUME® Steel

INTRODUCTION
The single aspect most frequently vexing prospective users of zinc-coated and zinc/aluminum alloy- coated steel sheet is cut edge performance. It is an estab- lished fact the sacrificial protection afforded to the steel at cut edges will delay corrosion while there is zinc or zinc/aluminum alloy left in the vicinity of the edges. Almost every metal coated steel product has cut edges and when piercing occurs within the area of the sheet a further “cut” edge is generated.

Prime examples of such products are roofing, gutter- ing and spouting. These items are first slit-to-width then cut-to-length. Holes are often pierced to accom- modate fasteners; however corrosion in these areas has never constituted a problem. Regardless of the environment, when more metallic coating is present, the steel has more protection both on flat unmarked surfaces and at cut edges.

Measure of Protection
Zinc/aluminum alloy hot dip metallic coated steel sheet is produced by passing continuous steel strip through
a bath of molten metal. As the strip emerges from the bath the thickness of the coating is precisely adjusted according to the coating class required. The coating class is a designation describing the coating type and amount of coating applied.

The coating type is generally described by the capital letter of the chemical symbols of the metals in the coating. The amount of coating is indicated by the minimum “coating mass” measured by the triple spot test specified in ASTM A792/A792M– 06.

The severity of the intended application should dictate the coating class specified. Heavier coating thicknesses should be used in more severe environments.

Two Way Protection
The zinc/aluminum alloy metallic coating performs in two ways:

The aluminum acts as a barrier when the steel base is completely enclosed by the coating. Protection is afforded by the corrosion resistance of the coating itself.
As a sacrificial coating at edges when the barrier is broken by slitting, shearing, piercing or scratching. The barrier effect is universally recognized. However, it is the sacrificial protection this bulletin addresses.

Protection is Automatic
Complete coating of steel sheet products is not practical, economical or generally necessary. It is normal practice and has been since zinc-coated sheet has been produced, to have slit, sheared, drilled or sawn edges.

In service, galvanic action causes zinc compounds to automatically build up at cut edges and scratches by an electrolytic reaction when water or moisture is pres- ent. These slow the rate at which the surrounding coat- ing is consumed around damaged areas. This effect is sometimes referred to as the “self-healing” property of coatings containing zinc.

Examples:  Coating Classes AZ50	AZ = Aluminum/Zinc
50 = Minimum of .50oz./ft², the total on both sides.

Comparison of Zinc and Zinc/Aluminum Coatings It is natural with the wide spread use of ZINCALUME® Steel sheet in traditional zinc-coated building appli- cations, the question of comparative cut edge perfor- mance should be raised. Unpainted ZINCALUME Steel will perform in a very similar manner to zinc-coated sheet in the relatively thin range of thickness associat- ed with roofing, wall cladding, gutters and down-pipes.

This has been tested by removing coating of similar thickness from ZINCALUME Steel and galvanized sheet down to the steel base, using scribe marks ranging from .016" to .16" in width. When exposed to the atmosphere, the differences in the samples are slight, particularly at the thinner scribe marks.

Guidelines for Welding ZINCALUME® Steel

INTRODUCTION
ZINCALUME® Steel can be readily welded using resis- tance and arc welding techniques. Utilizing conventional welding techniques along with the guidelines given below, ZINCALUME Steel can be as easily welded as other coat- ed sheet products. In general, the Al/Zn coating is soft and conductive compared to uncoated sheet steel and, therefore, requires higher welding currents, welding times and electrode forces for resistance welding. The param- eters used for successfully welding ZINCALUME Steel sheet are very similar to those for galvanized sheet.

Spot Welding
The optimum tip geometry which provides the longest electrode tip life when spot welding ZINCALUME Steel sheet is the truncated cone with either a 90° or 120° included angle. Pointed, domed or radius electrodes should be used only where necessary for reasons of access or alignment.

Testing has shown that a dispersion-strengthened copper alloy electrode will provide superior electrode life and welding characteristics when compared to RWMA Class 2 Cu-Cr or Cu-Zr alloys. Typical spot welding schedules for ZINCALUME Steel sheet are given below:

Electrode maintenance is also important in spot welding coated sheet steels. The parameters given above will cause gradual deformation of the contact surfaces as

well as the coating alloying with the electrode material. These factors require the electrodes be redressed more frequently than is the case with uncoated steel. The electrode tips should be redressed periodically, but the time between re- dressings depends on the sheet thick- ness and conditions of use. Additional factors influenc- ing electrode life are proper tip alignment and sufficient water cooling (minimum 2 gal/min) to the electrode.

The peel test, which is commonly used as a measure of nugget size and weld soundness, can be used to test the quality of spot welds on ZINCALUME Steel sheet. Test specifications vary among manufacturers, but in general, two coupons are welded together and then peeled apart. Under proper welding conditions, failure should occur around the weld, not through the weld.
The nugget diameter should approximate the diameter of the electrodes.

Seam Welding
The conditions for seam welding ZINCALUME Steel sheet are similar to those for galvanized steel in that higher currents and closer control of welding schedules are required than for uncoated sheet steel. Intermittent current feed is preferred over continuous current and 0.5-inch radius faced electrodes can be used for all sheet thicknesses if desired.

Schedules for seam welding ZINCALUME Steel sheet are

Material Thickness (in.)	Welding Current (amperes)	Electrode Force (lb)	Welding Time, Cycles (1/60 second)	Electrode Face Diameter (in.)	
0.028	11,300	400	12	0.187	
0.036	12,500	500	14	0.250	
0.040	12,800	500	14	0.250	
0.053	13,000	550	14	0.250	
0.065	13,400	650	18	0.250	
Actual requirements will vary depending on the job conditions.

Material Thickness (in.)	Electrode Face Type	Electrode Thickness (in.)	Electrode Force (lb.)	Welding Current (amperes)	Weld Time Cycles Heat	Weld Time Cycles Cool	Welding Speeds (in./min)	
0.017	1/2" Radius	3/8	700	14,500	2	2	60	
0.022	1/2" Radius	3/8	850	16,000	3	2	60	
0.034	1/4" Flat	1/2	1,000	21,500	4	2	60	
0.049	1/4" Flat	1/2	1,100	22,000	4	2	60	
	1/4" Flat	1/2	1,100	23,000	4	1	90	
0.083	5/16" Flat	5/8	1,600	27,000	10	6	30	

suggested in the table above. As with the spot welding schedules, the conditions below may need alteration depending on the job.

Seam welding wheels should be RWMA Class 2 copper alloy. Knurled wheels are preferred because the knurled drive rollers continuously remove pick-up from the sheet coating and maintain a constant face width, thus elimi- nating the need for redressing. The electrode wheels in the weld area should be flushed with water during welding to provide adequate cooling.

High/Low-Frequency Welding
ZINCALUME Steel has been fabricated into products such as tubing using both high-frequency and low fre- quency welding techniques. Standard procedures similar to those employed for galvanized or aluminum coated steels are used. Since the coating may smear at sheared or slit edges, it may be necessary to scrape the sheet edges prior to welding.

Arc Welding
Gas tungsten-arc (TIG) welding of ZINCALUME Steel is not recommended because, as with galvanized sheet
steel, fumes generated during welding tend to contami- nate the tungsten electrode and cause instability of the arc. Shielded metal-arc welding is best accomplished using E60XX electrodes, such as E6010, E6011 or E6012. A whipping technique is often used to burn off the coating ahead of the puddle. For gas metal-arc (MIG)

welding, a mild steel wire should be used with Ar/1% 02 or Ar/CO2 shielding gas. Gas containing Ar provides a more stable arc resulting in better bead appearance and significantly less weld spatter. When a backup plate is used, the plate should be grooved under the weld to
provide better penetration and venting of fumes from the underside of the weld.

Fuming
In arc welding, the total weight of evolved fumes per unit weld area for ZINCALUME Steel sheet is 25 percent of the amount for galvanized. The ratio of the amount of zinc oxide released from ZINCALUME Steel is only 20 percent of the amount released from galvanized sheet.
The decreased fuming of ZINCALUME Steel represents a reduced fume hazard to welders, but the extent of
fuming is still sufficient to require the use of fume hoods and/or forced exhaust systems. Fuming during resis- tance welding is very slight and special exhaust systems should not be needed.

Corrosion Resistance of Welds
As is the case with other coated sheet steels, spot and seam welding may remove the coating from ZINCALUME Steel sheet exposing the base steel. These areas may
be too large to be galvanically protected by the adjacent coating and should be covered with metal-sprayed zinc or aluminum, zinc-rich paint or organic coating. Covering the weld area of arc welds is especially important because the damage to the coating is even more severe.

Unsuitable Applications for ZINCALUME® Steel

INTRODUCTION
ZINCALUME® Steel has proven to exhibit superior corrosion resistance in a diverse range of environments including those in rural, industrial, marine and severe marine regions of the country.

Atmospheric corrosion testing for more than 30 years has clearly shown that ZINCALUME Steel has at least 2-4 times the life span of galvanized G90 in these
environments. However, with even the most revolutionary materials there are specific end user applications into which ZINCALUME Steel should not be placed without careful consideration as to the ultimate performance.

These applications, and issues to be considered within these applications, are summarized in this
Technical Bulletin to assist in the correct selection of materials.

Animal Confinement
Structures erected to house the intensive farming activities of pigs, cattle, turkeys and chickens can present problems for ZINCALUME Steel. This form of animal confinement can result in the creation of animal waste and waste decomposition by-products which can be extremely aggressive towards ZINCALUME Steel, creating significant corrosion problems.

Waste decomposition gases such as methane, hydrogen sulfate and ammonia can combine with water vapor to form a highly corrosive compound which condenses on the bottom side of the steel roof panel, resulting in an extremely corrosive attack. Direct contact with animal wastes should be avoided regardless of the type of material employed in the construction of the building. Good panel insulation, ventilation and frequent waste

removal will assist in maintaining the longevity of such a structure; however we recommend the following guidelines:

ZINCALUME Steel (bare or painted) should not be used for cattle, pig or poultry confinement due to the risk of the corrosive process outlined
above. Heavy zinc coated galvanized or aluminum products should be used for these applications.
ZINCALUME Steel will perform favorably in the majority of other agricultural applications. Such structures include storage sheds, silos, grain bins and other utility farm buildings.

Concrete
ZINCALUME Steel is not suitable for use with wet concrete mixtures (including mortar or stucco). It is not recommended for use in framework and floor
deck applications. The aluminum in the ZINCALUME Steel coating will react with the wet concrete leaving the coating porous and prone to corrosion. Adhesion between the concrete and ZINCALUME Steel is poor and the concrete itself can expand and lose strength. Small splashes of concrete onto ZINCALUME Steel are damaging, and should be removed when wet.

Culverts
ZINCALUME Steel is not recommended for applications involving burial in the earth or soil. Soils vary widely in moisture content, acidity or alkalinity. Objects buried in the soil can be subject to bacterial activity and oxygen levels can be highly variable. ZINCALUME Steel is more sensitive to low oxygen levels and lack of passivity than galvanized products, hence heavy coating mass galvanized would be the recommended product under these conditions.

Miscellaneous Sources of Aggressive Substances
The following specific applications should also be treated with caution. Contact Steelscape to seek advice on the correct material to use in these instances.

Some chemical, food processing and acid pickling plants where chemicals, acids and alkalis are present such that when combined with water vapor and dew point effect.
Direct contact with or runoff from green lumber or chemically treated lumber containing copper. A white paper on ZINCALUME Steel contact with pressure-treated wood is available upon request. Where copper/chrome/arsenate treated lumber is specified it must be well dried after treatment and insulated from the roof 
Copper containing mildew inhibitors, such as copper oxychlorate, should not come in contact with ZINCALUME Steel. Rinse immediately if contact occurs.
Dirt, leaves and build-up of organic matter.
Avoid direct contact with the ground/soil, foundations or sills.
Food or beverage container or contact should be avoided. The surface treatments used in ZINCALUME Steel can become soluble when in contact with food acids.
Sustained or frequent temperatures in excess of 390°F should be avoided with ZINCALUME Plus Steel (acrylic coated).

Guidelines to the Effective Use of ZINCALUME® Plus Steel

INTRODUCTION
The standard ZINCALUME Plus Steel coating is a specially formulated water-based resin film, which is factory applied over the ZINCALUME Steel surface. In the cured state the coating is colorless, odorless and imparts a satin finish to the surface of the product. It aids in
the roll forming process often eliminating the need for lubricants and also prevents fingerprinting.

The clear resin film is applied wet, using state-of-the-art roll coaters installed between the chromate application station and the delivery section. The roll coaters are similar in design and operation to those used on a coil coating line. The film is cured using computer controlled ovens. This ensures that optimum coating properties are achieved prior to rewinding and shipping.

The resin film has excellent adhesion to the substrate with very good impact resistance and flexibility. When it is used without post painting, the natural weathering process will gradually erode the clear coating from
the surface over a period of 12-18 months, without powdering, peeling or cracking. No significant changes in surface appearance will be evident.

In addition to the standard ZINCALUME Plus coating, we also offer a resin film designed specifically for end- use applications that involve adhesives such as plywood
sandwich panels and foam insulation. A Steelscape Sales Representatives can help to determine which resin film is right for any specific end-use application.

FIELD PAINTING GUIDELINES
Wet Painting
Both ZINCALUME Steel and ZINCALUME Plus Steel are readily over painted provided paint manufacturer’s

recommendations are followed and appropriate consideration is given to environmental conditions, end use, location and product application. Traditionally
ZINCALUME Steel requires the surface to be painted also be washed with a suitable solvent to remove traces of residual roll forming lubricant, and suitable metal primer be applied before the application of a decorative topcoat.

ZINCALUME Plus Steel removes the requirement to use solvent to clean up surfaces. A simple detergent wash is satisfactory, and eliminates the need to prime the surface. Solvents or harsh chemical cleaners should not be used. ZINCALUME Plus Steel can be readily over-painted with a high quality water based acrylic topcoat without priming, provided a lubricant has not been used in the forming process and the surface is clean and dry.

Solvent based finish coat systems may be used, however, these must be applied after the material has been primed with a water based, solvent resistant primer. If the material is correctly primed a number of coats may be applied. Surface preparation and priming must be in accordance with the paint manufacturer’s instructions.

Additional cleaning recommendations and field painting guidelines can be found in Technical Bulletin #11 “Guidelines for General Field Maintenance of ZINCALUME Steel Roofing and Siding”

Powder Coating
ZINCALUME Plus Steel is suitable for direct powder coating, provided the surface to be coated is clean and powders requiring a peak metal temperature in excess of 390°F are not used. It is recommended a brief

water wash serve as the only pretreatment step, rather than another form of solvent-based cleaning solution. Condensation can also occur on tightly bundled stacks of sheets or panels of ZINCALUME Steel. In its very early stages, it may appear as a white stain similar to the white oxide that can form on galvanized steel. Even pre-painted and roll formed ZINCALUME Steel sheet is not immune to this type of oxidation.

Roll forming Characteristics
Lubricants are rarely required during the roll forming of ZINCALUME Plus Steel because the clear resin film acts as a solid lubricant. The need for additional lubricant must be determined, however, on a case
by case basis. Variables to be considered include roll former design, (number of stands and severity of each incremental shape change) speed, surface condition of rolls and general machine maintenance.

Most common roof and sidewall trapezoidal shapes do not require additional lubrication if the roll former is well maintained and correctly set up. Very severe
profiles may require a small amount of spot lubricant at the heaviest worked points.

BENEFITS OF USING ZINCALUME PLUS STEEL:
No Pickup - The reduction or absence of pickup during forming due to the resin film means the reduction or elimination of time-consuming cleanup.
Increased Tool Life - Reduced pickup combined with the lubricating benefits of the resin film will contribute to improved tool life in manufacturing and roll forming applications.
Scheduling Flexibility - ZINCALUME Plus Steel can typically be roll formed interchangeably with
pre-painted feed avoiding the need for intermediate roll cleaning. This provides greater scheduling flexibility.
Removal of Hazardous Work Place Chemicals
- Hazardous substances such as kerosene and other lubricants can be removed from the work environment improving occupational health and safety practices.

Less Slippery - The resin film is less slippery than a lubricated steel surface particularly with the absence of residual lubricant left over from roll forming. This will make the product safer to walk on while installing, particularly in wet conditions.
Improved Final Appearance - Residual lubricants can often create a patchy visual appearance as the result of uneven drying off of the lubricant. This problem can usually be avoided with ZINCALUME Plus Steel.

Resistance to Marking
ZINCALUME Plus Steel resists marking and stains occurring during manufacturing, handling or fixing. The coating acts as a surface sealant, protecting the metal surface from hand and boot prints. CAUTION - during transportation of coil, sheets or formed panels, galling or abrasion of the resin coating can occur when one resin surface vibrates, or rubs, excessively against another resin surface. It will present as black marks, which are often mistaken for black rust, but it is not rust. Galling of the resin surface is strictly aesthetic in nature; the long term performance of the product is unaffected.

Wet Stack Storage Stain Resistance
The resin coating has an increased resistance to wet stack storage stain. Such stains appear black, and are caused when the material is packaged and subjected to moisture ingress between production and final
use. The coating acts as a barrier coat, preventing any chemical action from occurring. Recommended
storage should still be followed as outlined in Technical Bulletin #1 “General Guide to Good Practice in the Use
of ZINCALUME® Steel for Roofing & Siding Products” and Technical Bulletin #10 “Prevention of Oxide Formation (Black Rust) on ZINCALUME Steel During Transportation, Processing and Storage” 

INSTALLATION OF ZINCALUME PLUS STEEL
Flashings
The recommendations for flashing ZINCALUME Plus Steel are the same as for ZINCALUME Steel. Copper and lead are incompatible with ZINCALUME Steel and neither of these metals should be used in contact with

ZINCALUME Plus Steel. For further information refer to Technical Bulletin #2 “Flashing Materials for Bare & Pre- painted ZINCALUME Steel.”

Sealants
Tests show common neutral cure silicon sealants will adhere to the resin film. The adhesion properties of the resin film are the same as ZINCALUME Steel. Refer to Technical Bulletin #5 for “Sealants for ZINCALUME Steel” for additional information 

Fasteners
Recommended fasteners for ZINCALUME Plus Steel are the same as for ZINCALUME Steel. Refer to Technical Bulletin #3 for further information on “Fastener Selection for ZINCALUME Steel Roof & Siding Products ”

Slitting ZINCALUME Plus Steel
Where friction drag pads are used to maintain processing tension during slitting/recoiling, pickup of the resin can occur. Some chromate is present in this pickup, as it is with most ZINCALUME Steel, therefore, the following guidelines are recommended:
Use minimal frictional forces on pads.
Set minimum pad width 6" to minimize frictional forces if drag pads are used.
Encourage use of an appropriate respiratory device for personnel working in close proximity (4-6 Feet) if dust is produced by the drag pad.
Remove pickup from drag device and adjacent areas using appropriately designed apparatus.
Dispose of drag pads in accordance with environmental or local regulations.
Welding
Spot, seam or gas metal arc welding can be carried out successfully on ZINCALUME Plus Steel. Fume generation may be slightly higher than ZINCALUME Steel without the coating. All welding should be carried out in well

ventilated areas.

High Temperatures
The maximum recommended continuous service temperature is 390°F. Service temperatures exceeding 390°F will be detrimental to the coating. Applications requiring operating temperatures up to the 600°F
safe limit for ZINCALUME Steel should be specified without the resin film.

General Corrosion Characteristics
The ZINCALUME Plus coating does not improve the general corrosion characteristics of ZINCALUME Steel. As discussed in the introduction the coating degrades when exposed to ultra violet light. The resin film will not negatively impact the superior corrosion performance of ZINCALUME Steel.

Product Mixing
ZINCALUME Steel and ZINCALUME Plus Steel should not be mixed in adjacent areas on the same
building. The different surface finishes, both in the new and weathered conditions, will result in a contrasting appearance which may be objectionable.

Visual Reflectivity
ZINCALUME Plus Steel is no more reflective than ZINCALUME Steel.

Electrical Conductivity
The resin film applied to ZINCALUME Plus Steel can potentially cause an insulating effect between
panels in electrical appliance applications. The insulating effect would normally be overcome with welding or mechanical fastening of components. Manufacturers should be advised to ensure products are adequately grounded.

Prevention of Oxide Formation (Black Rust) on ZINCALUME® Steel During Transportation, Processing and Storage
INTRODUCTION

ZINCALUME® Steel is a proven product exhibiting superior long-term corrosion resistance in a multitude of atmospheric environments. However, as with any steel product, there are precautions which must be
observed during receiving, handling, processing, shipping, storage and assembly of ZINCALUME Steel products. If no precautions are taken, oxidation (i.e. black rust) can occur. This technical bulletin briefly describes the various sources of oxidation affecting the typical ZINCALUME Steel end user. This technical bulletin also provides guidelines to prevent the occurrence of oxidation and how to potentially remove an oxidation stain if it occurs.

SOURCES OF OXIDE FORMATION ON ZINCALUME STEEL
Oxide stains can occur on either coils or tightly bundled sheets of ZINCALUME Steel. Although oxidation of the metallic coating is usually superficial and confined to the extreme upper layer of the coating, it is aesthetically displeasing and can quickly become more severe if the cause of the stain is not removed. In the most severe instances, there can be a weight loss of metallic coating and a potential reduction of service life. When the cause of an oxidation stain is removed or (in the case of a formed panel) when affected panels are assembled at the job site, the oxidation stain will not worsen.

The basic cause of an oxide stain on ZINCALUME Steel is water or moisture interacting with the metallic coating in an oxygen-deficient environment. Under normal service conditions, ZINCALUME Steel has

excellent durability because of a protective oxide formed when the coating comes into contact with air. However, when moisture is in contact with the strip, and the strip is tightly stacked or wrapped into a coil, there is no exposure to air allowing the barrier oxide layer to form. As a result, accelerated corrosion is initiated. Oxide stain can occur in this type of oxygen-deficient environment in less than 48 hours.

Condensation
Oxidation can occur due to condensation when cold steel is moved from out of doors into a warmer building. The moisture in the air of the warmer building can condense on the colder steel surface. The presence of condensation-type oxide is typically identified as a dark gray oxidation condition which subsequently becomes darker. It is distributed on the material in a generalized pattern (rather than localized). A condensation-type oxide pattern occurs inward from both edges of the strip and is shallow in penetration from the edges.

Steel products must not be exposed to combinations of temperature and humidity which can result in condensation. Steel products should not be allowed to vary by more than 20°F from their surrounding
environment. If an incoming shipment of ZINCALUME Steel appears to exceed 20°F difference from the storage environment, the product should be allowed to warm slowly in a cooler indoor area free from cold air drafts. All material storage areas must be properly ventilated with adequate circulation of air. Circulation of air, however, should not be defined as allowing doors to remain open where moist air from the outside can enter the building and increase the probability of condensation.

Condensation can also occur on tightly bundled stacks of sheets or panels of ZINCALUME Steel. In its very early stages, it may appear as a white stain similar to the white oxide that can form on galvanized steel. Even pre-painted and roll formed ZINCALUME Steel sheet is not immune to this type of oxidation.

Wet Storage
Oxidation can occur due to transport or storage of the steel in a wet environment. Oxidation frequently occurs when the material comes in direct contact with water during transportation to the end user facility or job site.
In such a situation, the material will have evidence of water penetration by capillary action, from the side wall of the coil or the edge of a sheet (in the case of formed sheets). The oxide penetrates deeper into the
metallic coating and becomes more difficult to remove than a condensation type condition. Oxide occurs
as a more localized pattern than general across the entire surface. Oxidation also will occur within stacks of tightly bundled sheets when the stack comes into direct contact with water while the sheets are bundled at the end user facility or job site. In its very early stages, it can appear as a somewhat removable, white stain, similar to the oxidation stain that can form on galvanized steel. Even pre-painted ZINCALUME Steel is not immune to wet storage oxidation.

Other sources of oxidation could evolve during processing of the ZINCALUME Steel itself.
Inadequately cured surface treatments or water-based remnants of forming lubricants allowed to remain
on the surface during storage will provide entrapped moisture for oxide formation. The net effect would be a dark oxidation stain (rust) with a linear and blotchy pattern not necessarily associated with the edges.

PREVENTION OF OXIDE FORMATION ON ZINCALUME STEEL
The Steelscape ZINCALUME Steel production process incorporates surface passivation, resin coating and oiling capabilities to minimize the potential of oxide formation on the finished product during transportation and storage. Steelscape recommends, depending on what treatment an order has received, coils should be properly stored no longer than the periods listed below.

Product Ordered	Max. Storage Period after Ship Date	
ZINCALUME Steel - Oiled/No Chem.-treat	3 months	
ZINCALUME Steel - Chem.-treat/Dry	4 months	
ZINCALUME Steel - Chem.-treat/Oil	6 months	
ZINCALUME Plus Steel	6 months	

Responsibility of the Steel Fabricator
To prevent the occurrence of an oxidation stain, the following precautions should be practiced by a fabricator.
Order ZINCALUME Steel product with an optimum combination of surface treatment, oil and coil packaging.
Verify any transit carriers adhere to shipping instructions and provide optimum protection to the steel coils during transit to the fabrication plant.
Inspect ZINCALUME Steel coils for moisture upon arrival and stock ZINCALUME Steel coils indoors in a clean, dry area away from any sources of chemical pollution.
Establish defined coil receiving inspection procedures which establish carrier responsibility.
Document transit-related water damage on the manifest. Photos or video must be taken of any questionable condition.
Documentation should include the following elements:
Weather conditions at time of delivery.
Tarp or protective equipment conditions/ exceptions.
Equipment conditions/exceptions.
Coil conditions, (i.e., wet, package damage, etc.).
Notify Steelscape as quickly as possible when oxidation of the surface is confirmed 
Store ZINCALUME Steel product at an even temperature above the dew point with adequate air circulation to prevent condensation problems.
Remove plastic or paper packaging upon arrival, if the storage area is heated and dry. If the material

is wet, the sheets should be wiped dry. Wet coils should be scheduled into production as soon as possible.
Inspect the storage site regularly to ensure standing moisture has not penetrated the ZINCALUME Steel coils.
Stack the product on wood or metal skids so that the coils are not in contact with the ground and elevate one end of each bundle to allow any
moisture to run off rather than puddle on the top of the bundle or between nested panels.
Ensure ZINCALUME Steel roll formed sheets are paper-wrapped when the sheets are not scheduled for erection on the day of delivery.
Avoid using plastic material for covering. Non- breathing materials should not be used to shroud bundles because they tend to trap moisture.
Verify transit carriers adhere to shipping instructions and provide optimum protection to the steel sheets during transit to the job site.

Note: To correctly wrap a bundle of ZINCALUME Steel sheets, the bottom paper sheet is put in place first and the top laps are covered smoothly with the top covering sheet with the folds underneath the bundle. If folded improperly, the laps on top can create a catch for water and actually encourage accumulation of water in transit.

Responsibilities of the Erector at the Job Site To prevent the occurrence of an oxidation stain, the following precautions should be practiced by an Erector at a job site:
Inspect bundles on arrival at the building site and note on the delivery receipt any exceptions such as damage, corrosion or wet material.
Store the bundles on racks at least one foot above ground level. Do not use uncured lumber.

Use under-roof storage when possible. If the bundles must be stored in the open on bare ground, a plastic ground cover should be used under the bundles to minimize condensation on the sheets from moisture in the soil.
Elevate one end of the bundle to allow moisture to run off rather than puddle on the top of the bundle or between nested panels. Water resistant paper will not keep out puddled moisture beyond its rated moisture vapor transmission time.

Removal of Oxide Stains on ZINCALUME Steel The oxide stain (black rust) that forms on ZINCALUME Steel sheet is primarily a hydrated aluminum oxide and can be very difficult to remove if progressed beyond the initial stages. In mild cases the oxide may be removed by using a solvent, such as mineral spirits, applied to a cloth. Mineral spirits would also be used to remove an oxide stain from pre-painted ZINCALUME Steel without damaging the paint. A mild, nonabrasive household cleanser may also be successful in removing the stain from a panel.

In more severe cases, industrial solvents may be used. However, as more aggressive chemicals are used to remove the stain, there is an increased possibility for damage to the coating itself. Harsh alkaline cleaning solutions should never be used. High pressure sprays should be avoided. Steel wool should never be used to remove an oxide stain from ZINCALUME Steel since it is too abrasive and it will leave embedded iron files causing a cosmetically displeasing red rust condition.

In all cases of oxide stain, removal of the stain will affect the appearance of the metallic coating under and near to the stain. The area near the stain will usually appear duller after the stain is removed.

Guidelines for General Field Maintenance of ZINCALUME® Steel Roofing and Siding
INTRODUCTION

Minimum maintenance of ZINCALUME® Steel, whether bare or pre-painted, is required. Both are highly durable and simple maintenance by regular washing with clean water will enhance the service life of the product and maintain the appearance.

“Unwashed areas” are areas on a building that are sheltered from general rainfall and are therefore not naturally washed. Condensation can be absorbed by the dust and dirt that build up in these areas, leading to an increase in the time that the material is in contact with sufficient moisture to initiate corrosion. The associated affect is exacerbated in the vicinity of a salt marine influence, where the build-up includes marine salts and/ or other pollutants. Regular cleaning of ZINCALUME Steel products in unwashed areas is required. Examples include, but are not limited to, fascia, wall cladding under eaves, garage doors, and the underside of eave gutters, carports and patios.

Washing should be done six monthly as a minimum. More frequent washing may be necessary in coastal areas or where high levels of industrial fallout/pollution occurs.

Cleaning
While factory-applied finishes for metal building panels are so durable that they will last many years
longer than ordinary paints, it is desirable to clean them thoroughly on a routine basis whenever the finish is
not washed by rain. Cleaning will generally restore the appearance of these buildings and render repainting unnecessary. An occasional light cleaning will also help maintain an aesthetically pleasing appearance.

In cases where regular maintenance using fresh water does not remove all dirt from the surface of the product the following procedure should be used;
Wash the surface with a mild solution of pure soap or non-abrasive dish washing detergent in warm water. Washing should be conducted with a sponge, soft cloth or soft bristle nylon brush (no abrasive scourers, steel wood, etc). Care should be taken not to scuff the surface of the product.

Note: The use of detergents containing greater than 0.5% phosphate is not recommended for use in general cleaning of building panels. NEVER BLEND CLEANERS AND BLEACH 

As an alternative one cup of household ammonia dissolved into five gallons of water (room temperature) could also be used.
Using either solution work from the top to the bottom of the panels, gently removing dirt and debris. A low pressure spray washer may aid in removing dirt deposits. Solvent-containing cleaners, such as Fantastic®, are effective and can be used without concern.
If mildew or other fungal growth is a problem and cannot be removed, a mix of household bleach, one gallon to five gallons water, together with one cup of mild soap (Ivory® is recommended), can be used.
The surface should be thoroughly rinsed with freshwater immediately after cleaning to remove traces of any detergent or cleaner.

Additional Maintenance
The long term performance of ZINCALUME Steel can at

times be impacted by the durability of the accessories which are in contact with the product. For example, the deterioration of the fasteners used can result in sacrificial corrosion of the product in the areas immediately adjacent to the fasteners. It is a good practice to;
Ensure that fasteners used comply with Technical Bulletin #3 “Fastener Selection for ZINCALUME Steel Roof and Siding Products”
Regularly inspect the fasteners and consider replacing any showing evidence of red rusting.

FIELD PAINTING
Pre-painted ZINCALUME Steel and ZINCALUME Plus Steel are both coated with factory applied, oven cured coatings. While both are intended to be installed as is and will have long term durability
and performance, there may be instances when field painting over the factory finish is required. The guidelines presented here are also applicable to bare ZINCALUME Steel. The following should be considered;
Air drying paints have different weathering characteristics to pre-painted ZINCALUME Steel and are typically not as durable. Areas field painted with air dry paints to match adjacent factory applied areas may weather different over time and therefore vary in appearance.
The color and gloss of air dry paints may not exactly match that of the factory applied paint.
Field painting over the factory applied finish voids any originally issued paint warranties.

Surface Preparation
It is normal practice to ensure that any surface to be painted is in a suitable condition for painting. The most appropriate preparation is dependent on the age and condition of the surface.

Any dirt, debris or mildew must be removed; follow the cleaning guidelines outlined above in this bulletin. Rinse the surface thoroughly as residual cleaners or detergent left on the surface could result in poor adhesion of the field applied coating.

Bare ZINCALUME Steel product should be cleaned with

solvent to remove any rolling oils or lubricants. Rinse thoroughly and allowed to dry completely.

Minor scratches which have not left the metal substrate exposed can be lightly sanded or buffed to create a smoother surface. Care must be taken to avoid exposing the substrate.

To prevent rust from forming on exposed metal, sand the general area lightly and use a high-quality primer to
protect the exposed metal from corrosion. Allow sufficient time (normally 24 hours) for the primer to dry before applying the topcoat. If either red or white rust is evident, remove as much rust as possible with a wire brush, and then sand lightly to remove all rust. Wipe the exposed area with mineral spirits before priming.

Field Paint Types
The most suitable field paint type is generally water-based acrylic. However, in more corrosive salt marine locations, or for severely rusted material, it may be necessary to choose a paint system that has enhanced corrosion resistance such as a zinc-rich primer.

Due to ongoing improvements in paint technologies, at any given time there are numerous potentially suitable paint products available. It is therefore recommended that a reputable paint supplier or contractor be consulted to determine the most appropriate paint system for your particular applications and environment.
Read manufacturer’s instructions and observe them explicitly. Thorough mixing is essential.
It is not advisable to use different brands of primers and finishing coats in conjunction with one another. Do not over paint water-based paints with oil or organic solvent-type paints.
At all times, avoid excessive paint film thickness such as may occur in the valleys of formed roofing panels.
When extensive areas are to be covered, spray painting can lower cost while giving acceptable results. The paints used, however, must be formulated for this purpose.
Work safely. Wear proper safety equipment; ensure good ventilation in paint handling; avoid unnecessary contamination of the skin.

TOUCH-UP PAINT
Scratches and very minor damage may occur during handling and installation of painted roofing and walling. In these instances, it may be desirable to use touch-up paint to repair the blemishes. Keep in mind touchup paints are quick fixes and when used properly will result in satisfactory appearance. Misuse or over- use can result in spoiling the overall appearance.

Small scratches that do not penetrate through the metallic coating of the ZINCALUME Steel and are not noticeable from 6ft. should be left alone as the metallic coating will protect against corrosion.

Surface Preparation
Edges of deep scratches should be lightly sanded or “feathered” with 400 grit sandpaper. If a scratch extends through the paint and the protective metal layer exposing raw steel, it should be treated with a
zinc rich or similar primer before touch-up application. If feathering and/or priming are not necessary, areas to be touched-up should at least be wiped with mineral spirits to remove dirt, wax or other contaminants before colored touch-up is applied.

Paint Application
The recommended paint type for touch-ups is an acrylic silicone paint which can be found at local paint stores. Many panel fabricators have touch-up paint available in their standard colors as well.

Special attention should be paid to the manufacturer’s instructions, including direct skin or eye contact, ventilation and potential flammability. Aerosol or spray applications are not recommended for blemish or scratch repairs. The best tool for this type of repair is a good quality, 1/4-in. artist brush or a pen tip type applicator; only the narrow edge of the applicator should actually contact the scratch or blemish. Use touch-up paint sparingly and only to cover up those areas where paint has been removed. Excessive use of touch-up paint will result in a blotchy, uneven, appearance.

TECHNICAL BULLETIN

Guidelines to Installation of Photovoltaic Panels on ZINCALUME Steel

INTRODUCTION
When installing photovoltaic (PV or solar) panels to roofing made from ZINCALUME Steel the following installation and maintenance practices will assist in maintaining the water tightness and durability of the roof. This technical bulletin relates to the installation of framed PV/solar panels mounted above ZINCALUME Steel roofing.

INSTALLATION CONSIDERATIONS
Clearance Between the Panels and the Roof PV/solar panels installed on a ZINCALUME Steel roof shield the roof from the sun and prevent beneficial washing from rainfall. Areas on the roof directly beneath the panels are considered to be unwashed and may be subject to accelerated corrosion due
the accumulation of dirt, salt and other airborne contaminants which may retain moisture for extended periods due to condensation or high humidity. The provision of adequate clearance between PV/solar panels and roofing will help to:
Facilitate self-cleaning and limit the build-up of leaves and other debris.
Provide sufficient access for the cleaning, inspection and maintenance of the roofing material, including removal of any accumulated contaminants, and fasteners beneath the panels.
Allow air flow to quickly dry areas beneath the PV/ solar panels. This may also be beneficial to the performance of the PV/solar panels as electrical output is usually temperature dependent.

Compatibility of Materials with Roofing Made from ZINCALUME Steel
Dissimilar metals, such as stainless steel, lead, brass, copper and copper containing alloys should not be used in direct contact, or contact that could create an electrical connection, with roofing made from ZINCALUME Steel. This also includes conductive seals, washers and gaskets. Refer to Technical Bulletin #2 “Flashing Materials for Bare and Pre-painted ZINCALUME Steel” and Technical Bulletin #3 “Fastener
Selection for ZINCALUME Steel Roof and Siding Products” for additional information on dissimilar metals and galvanic corrosion.

Avoid PV/solar panels, or any introduced flashings, which utilize materials such as copper and lead as these materials have the potential to create water run- off onto roofing made from ZINCALUME Steel resulting in galvanic corrosion.

Ensure any sealant in contact with ZINCALUME Steel is “neutral cure” silicone.

Timber used in direct contact with roofing made from ZINCALUME Steel that has the potential to become damp can result in accelerated corrosion of the roofing. Furthermore, treated lumber has the potential to leach and drip corrosive substances onto the roof. Use of lumber on the top surface of the roof should be avoided.

Avoiding Potential Damage to the Roof
Foot traffic can dent, scuff, or scratch the ZINCALUME Steel roof.
Dents may need to be rectified to avoid water ponding, which is more likely on low pitch roofs. Ponded water

exposes ZINCALUME Steel to an extended period of wetness which may increase the potential for corrosion or water ingress.
Scuffing is typically an aesthetic issue that is unlikely to have any detrimental effect on the performance of roofing made with ZINCALUME Steel.

Maintaining Water Tightness of the Existing Roof The installation of PV/solar panels should allow for free drainage of moisture from all surfaces. Avoid ponding water.
Any penetrations through the roof should be placed in such a manner so as to minimize the risk of water ingress. Penetrations through the roofing should be
properly sealed using appropriate flashings, sleeves and/ or sealants. Non-penetrating attachment clamps are recommended if the design allows.
Avoid valley fixing or valley holes for electrical cables.
PV/solar panel fasteners and brackets should be installed away from sheet side laps as they may distort the profile and interfere with the specifically designed anti-capillary laps, leading to water ingress.

Rainwater Collection
If rainwater is collected from the roof, check with the PV/solar panel supplier to ensure it does not adversely affect water qualify.

Fasteners and Brackets
Fasteners and brackets used in the installation of PV/ solar panels should have a service life comparable to the expected performance of the ZINCALUME Steel. This includes the replacement of any corroded roofing fasteners that will be located beneath the new PV/solar panels.

Swarf
During installation swarf should be removed daily. Refer to Technical Bulletin #4 “Prevention of Damage to ZINCALUME Steel Roof and Siding Products from Metal Filings” for additional information.

Electrical Cables
Electrical cables should not sit directly on the roof panels as this may lead to the accumulation of dirt, salt and other contaminants. Cables should be affixed to the PV/solar panel support structure.

Grounding
Ensure appropriate grounding of the PV/solar system. Stray currents to the roof made with ZINCALUME Steel may accelerate corrosion.

MAINTENANCE
Unwashed areas have an increased risk of corrosion compared to washed areas, regular cleaning is recommended. Generally, unwashed areas should be cleaned with fresh, potable water, at least every 3 months for coastal or industrial areas, and at least every 6 months in other applications. This may coincide with periodic PV/ solar panel cleaning. Maintenance should also include
an inspection of the roofing fasteners, as well as the surface condition of the ZINCALUME Steel. For further guidance on maintenance refer for Technical Bulletin #11 “Guidelines for General Field Maintenance of ZINCALUME Steel Roofing and Siding”

Hawaiian Islands: Exceptions to Standard Limited Warranty, Cleaning and Panel Design Recommendations

INTRODUCTION
The volcanic activity on the big island of Hawaii is a unique but well understood natural feature. Two of the primary emissions from the vents located at Kilauea are hydrogen sulfide and sulfur dioxide. These particulates often result in the well known island haze called VOG. These two components when mixed with water droplets in the surrounding air can result in the formation of sulfuric acid which can become acid rain. Acid has long been known to cause corrosion on ZINCALUME® steel, both painted and bare, but historically the levels of sulfur on the island of Hawaii has been such that routine rainfall provided enough cleaning of roof panels to prevent any type of premature corrosion.

Unfortunately, the situation at the Kilauea summit has changed dramatically over recent years. The opening of a vent at the Halema`uma`u crater in December 2007 has resulted in a much higher level of sulfur dioxide being released into the environment, with a marked increase starting in March 2008. It is estimated that an additional 750-2,000 tons/day of sulfur dioxide is being released. Due to the increased corrosiveness on Hawaii, Steelscape is undertaking
a large scale exposure study to determine the best substrate, paint and panel design to minimize pre- mature corrosion. Until the results of this study are available, the following limited warranty exceptions and recommendations have been developed.

LIMITED WARRANTY GUIDELINES AND EXCEPTIONS
Big Island of Hawaii
For orders accepted after December 1, 2010, the below ZINCALUME® steel limited warranty durations

and distances will be in effect. All the standard and current ZINCALUME® steel limited warranty conditions and provisions will apply.

Distance from Halema’uma’u and/or Pu’u O’o Vents*	Limited Warranty Duration	
0 – 10 miles	5 years	
11 – 20 miles	10 years	
21 – 30 miles	15 years	
>30 miles	Standard 25 years	
*Halema’uma’u Vent 19°24"24.19’N 155°17’01.02"W Pu’u O’o Vent 19°23’21.47"N 155°06’20.51" W

Other Hawaiian Islands
The other Hawaiian Islands will be subject to the current standard ZINCALUME® steel limited warranty.

An exception to our limited warranty should be requested for any sites, Hawaiian or otherwise, located within one mile of the ocean as this zone is defined
as aggressive marine. Failure to submit a limited warranty request for aggressive marine locations may result in a voided warranty.

RECOMMENDING CLEANING PRACTICES
Big Island
Roof panels should be washed down with fresh water for a period of time sufficient to remove any debris, dirt or pooled water from the surface. Fresh water for the purposes of this technical bulletin is defined as potable, or drinkable with a 6-9pH. It is especially
important that no dirt or debris be left at the drip edges

of the roof panels. No cleaning solutions are necessary and panels should not be scrubbed. Recommended cleaning frequency is below.

Distance from Halema’uma’u and/or Pu’u O’o Vents*	Recommended Cleaning Frequency	
0 – 10 miles	Monthly	
11 – 20 miles	Every Two Months	
21 – 30 miles	Every Four Months	
>30 miles	Every Six months	

*Halema’uma’u Vent 19°24"24.19’N 155°17’01.02"W Pu’u O’o Vent 19°23’21.47"N 155°06’20.51" W
PANEL DESIGN
Panel Design and Effect on Corrosion
Our field inspections conducted to date indicate that panel design may play a significant role in the rate of corrosion due to acid rainfall and VOG from the volcano. Panels with an exposed cut edge and corrugated profile tend to hold small amounts of water and debris at the very edge due to capillary

Silt accumulation on a panel without a drip edge. Blistering of the paint is an early sign of corrosion.

action. Over time this concentration of acidic water and particulate matter begins to corrode the paint and eventually the substrate.

Profiles with a hemmed drip edge allow water and debris to flow off the panel, thus providing better long- term corrosion performance.

Section 2 - Hazards Identification

GHS Label Elements: Hazard Pictograms:

Signal Word:
Warning
Hazard Statement:
Does not pose a health hazard in its normal form. Inhalation of metal dust and fume may result from further processing by the user, particularly during welding, burning, grinding and machining activities. These potential health hazards should be evaluated by the user. A non-metallic passivation treatment is normally applied based upon customer/end use criteria. These non- metallic coatings may contain hazardous substances of varying amounts. During processing, substances of varying chemical composition and quantity may be generated by the surface passivant. MSDS information regarding the surface passivant shall be supplied to the user upon request.
Carcinogenity:
Certain chromium and nickel compounds as well as organic compounds found in various coating materials have been listed as carcinogens by the NTP, IARC, or OSHA.
Medical Conditions Aggravated by Long Term Exposure:
Individuals with chronic respiratory disorders (i.e., asthma, chronic bronchitis, emphysema, etc.) may be adversely affected by any fume or airborne particulate matter exposure.
Chronic Effects:
Chronic inhalation concentrations of iron oxide fumes or dusts may lead to a benign pneumoconiosis (siderosis). Inhalation of high concentrations of ferric oxide may possibly enhance the risk of lung cancer development in workers exposed to pulmonary carcinogens. Chronic inhalation concentrations of aluminum fumes or dusts may lead to a fibrotic lung condition known as Shaver.s disease; however, evidence for this is not conclusive since affected workers were exposed to other substances (silica) as well. The inhalation of high concentrations of dust from manganese, copper, lead and/or zinc in the respirable particle size range can cause an influenza-
like illness termed metal fume fever. Typical symptoms last 12 to 48 hours and are characterized by metallic taste in mouth, dryness and irritation of the throat, followed by weakness, muscle pain, fever and chills. Continuous exposures to high concentrations of manganese can cause central nervous system disorders and .manganese pneumonia.. Fibrosis of lung tissue from manganese exposure has also been reported for products containing manganese only. Overexposure to aluminum dust can cause shortness of breath. Long term inhalation exposure to high concentrations (overexposure) to pneumoconiotic agents may act synergistically with inhalation of oxides, fumes or dusts of this product to cause toxic effects. Prolonged or repeated contact with

unprotected skin may result in skin irritation. Torching or burning operations on steel products with oil or organic coating may produce emissions which can be irritating to the eyes and respiratory tract.
Precautionary Statement:
Inhalation of metal dust and fume may result from further processing by the user, particularly during welding, burning, grinding and machining activities. These potential health hazards should be evaluated by the user.

Section 4 - First Aid Measures
Eye contact:
Treat any foreign body in eye by flushing with large amounts of water. Seek medical attention immediately.
Skin contact:
Skin hazards are not expected. However, should dermatitis develop, affected area should be washed with mild soap and water. If irritation or other symptoms develop, seek medical attention. Precautions should be taken to protect against sharp steel edges. If the skin is abraded by handling, seek medical attention.
Ingestion:
Ingestion hazards are not expected.
Inhalation:
For treatment of overexposure to fumes and/or particulates, remove exposed individual to fresh air and seek medical attention. Administer artificial respiration or oxygen if breathing is difficult or has stopped.

Section 5 - Fire-Fighting Measures
Not flammable or combustible. Steel products in the solid state present no fire or explosion hazard and do not contribute to the combustion of other materials.

Section 6 - Accidental Release Measures
Not applicable to this metal in its solid state. For spills involving finely divided particles, clean-up personnel should be protected against contact with eyes and skin. If material is in a dry state, avoid inhalation of dust. Fine, dry material should be removed by vacuuming or wet sweeping methods to prevent spreading of dust. Avoid using compressed air. Do not release into sewers or waterways. Collect material in appropriate, labeled containers for recovery or disposal in accordance with federal, state, and local regulations.

Section 7 - Handling and Storage
Operations with the potential for generating high concentrations of airborne particulates should be evaluated and controlled as necessary. Practice good housekeeping. Avoid breathing fumes and/or dust.

Section 8 - Exposure Controls / Personal Protection
Respiratory protection:
NIOSH/MSHA approved dust and fume respirators should be used to avoid excessive inhalation of particulates. Appropriate respirator selection depends on the magnitude of exposure.
Hand protection:
Protective gloves should be worn as required for welding, burning or handling operations. If material is supplied with oil or other organic coating, wear protective gloves. However, do not continue to use gloves or work clothing that have become saturated with oil. Wash hands and any additional contact areas with soap and water or waterless hand cleaner.
Eye protection:
Use safety glasses or goggles as required for welding, burning, sawing, brazing, grinding or machining operations.
Engineering measures:
Local exhaust ventilation should be provided when welding, burning, sawing, brazing, grinding or machining to prevent excessive dust or fume exposure.
Personal protection equipment:
Operations with the potential for generating high concentrations of airborne particulates should be evaluated and controlled as necessary. Avoid breathing fumes and/or dust.

TECHNICAL BULLETIN

Guidelines for the Effective Use of TruZinc® Plus Steel

1 0 Properties of TruZinc Plus Steel 
The TruZinc Plus Steel coating is a specially formulated water-based resin-chrome film, which is factory applied over a bare TruZinc Steel surface. In the cured state, the coating is colorless and odorless.
The resin film has excellent adhesion to the substrate with very good impact resistance, flexibility, roll form- ability, storage stain corrosion resistance (far superior to conventional passivation), and anti- fingerprinting properties. When it is used without post painting, the natural weathering process will typically not affect the surface appearance for at least 12 months.

1 0 1 Factory Production of TruZinc Plus Steel The clear resin film is applied wet, using state-of-the- art roll coaters. The roll coaters are similar in design and operation to those used on a coil coating line. The film is cured using computer-controlled ovens. This ensures that optimum coating properties are achieved prior to rewinding and shipping.

1 1 Field Painting Guidelines 
1 1 1 Wet Painting 
TruZinc Plus Steel can typically be painted, provided paint manufacturers recommendations are followed and appropriate consideration is given to environmental conditions, end use, location and product application. Given the wide variety of available paint systems and applications, testing for specific compatibility is highly recommended. Traditionally, TruZinc Steel requires the surface to be painted also be washed with a suitable solvent to remove traces of residual roll forming lubri- cant, and suitable metal primer is applied before the application of a decorative topcoat.

TruZinc Plus Steel removes the requirement to use solvent to clean up surfaces. A simple detergent wash is satisfactory, and generally eliminates the need to prime the surface. TruZinc Plus Steel can typically be over-painted with a high quality water based acrylic topcoat without priming, provided a lubricant has not been used in the forming process and the surface is

clean and dry. Again, given the wide variety of available paint systems and applications, testing for specific compatibility is highly recommended.

Solvent based finish coat systems may be used, however, these must be applied after the material has been primed with a compatible water based, solvent resistant primer. If the material is correctly primed a number of coats may be applied. Surface preparation and priming must be in accordance with the paint manufacturer’s instructions.

1 1 2 Powder Coating 
TruZinc Plus Steel is suitable for direct powder coating, provided the surface to be coated is clean and powders requiring a peak metal temperature in excess of 390°F are not used. It is recommended that a brief water wash serve as the only pretreatment step, rather than another form of solvent-based cleaning solution. Please contact our Sales Department to discuss a program to trial TruZinc Plus Steel for these applications.
1 2 Roll forming Characteristics 
Lubricants are rarely required during the roll forming of TruZinc Plus Steel because the clear resin film acts as a solid lubricant. The need for additional lubricant
must be determined, however, on a case-by- case basis. Variables that should be considered include roll former design, (number of stands and severity of each incre- mental shape change) speed, surface condition of rolls and general machine maintenance. Most common roof and sidewall trapezoidal shapes do not require addi- tional lubrication if the roll former is well maintained and correctly set up. Very severe profiles may require a small amount of spot lubricant at the heaviest worked points.

The Benefits of Using TruZinc Plus Steel Include:
No Pickup - The reduction or absence of pickup during forming due to the resin film means the reduction or elimination of time-consuming cleanup.
Increased Tool Life - Reduced pickup combined

with the lubricating benefits of the resin film will contribute to improved tool life in manufacturing and roll forming applications.
Scheduling Flexibility - TruZinc Plus Steel can typically be roll formed interchangeably with pre- painted feed, avoiding the need for intermediate roll cleaning. This provides greater scheduling flexibility.

Removal of Hazardous Work Place Chemicals
- Hazardous substances such as kerosene and other lubricants can be removed from the work environment, improving occupational health and safety practices.
Less Slippery - The resin film is less slippery than a lubricated steel surface particularly with the absence of residual lubricant left over from roll forming. This will make the product safer to walk on while installing, particularly in wet conditions.
Improved Final Appearance - Residual lubricants can often create a patchy visual appearance as the result of uneven drying off of the lubricant. This problem can usually be avoided with TruZinc Plus Steel.
1 3 Resistance to Marking 
TruZinc Plus Steel resists marking and stains occurring during manufacturing, handling or fixing. The coating acts as a surface sealant, increasing protection of the metal surface from hand and boot marking.
1 4 Wet Stack Storage Stain Resistance 
The resin coating provides an increased resistance to wet stack storage stain. Such stains appear white, gray or black, and are caused when the material is packaged and subjected to moisture ingress between production and final use. The coating acts as a barrier coat, minimizing aesthetic degradation.
1 5 Installation of TruZinc Plus Steel
1 5 1 Flashings 
The recommendations for flashing TruZinc Plus Steel are the same as for TruZinc Steel. Using TruZinc Plus Steel or TruZinc Steel in areas subject to water runoff from ZINCALUME®, Pre-painted ZINCALUME, Pre- painted TruZinc Steel or aluminum coated steel should be avoided. TruZinc Plus Steel and TruZinc

Steel are not subject to pitting corrosion when used alongside lead or copper components. Similar to other metallic building materials, TruZinc Plus Steel and TruZinc Steel should not be used in direct contact with green, wet or chemically treated wood products.

1 5 2 Sealants 
Experience shows that TruZinc Plus Steel is compatible with polyurethane, PVC, and polypropylene, and therefore would likely be compatible with common neutral cure silicone sealants. The adhesion properties of the resin film should be similar to TruZinc Steel.

1 5 3 Fasteners 
Recommended fasteners for TruZinc Plus Steel are the same as for TruZinc Steel.
1 6 Slitting TruZinc Plus Steel 
Where friction drag pads are used to maintain processing tension during slitting/recoiling, pickup of chrome passivant can occur. Some chromate is
present in this pickup, as it is with most TruZinc Steel, therefore, the following guidelines are recommended:

Use minimal frictional forces on pads.
Set minimum pad width 6" to minimize frictional forces if drag pads are used.
Encourage use of an appropriate respiratory device for personnel working in close proximity (4-6 Feet) if dust is produced by the drag pad.
Remove pickup from drag device and adjacent areas using appropriately designed apparatus.
Dispose of drag pads in accordance with environmental or local regulations.

1 7 Welding 
Spot, seam or gas metal arc welding can be carried out successfully on TruZinc Plus Steel with typical resin coating weights. Fume generation may be slightly higher than TruZinc Steel without the coating. All welding should be carried out in well-ventilated areas.
1 8 High Temperatures 
The maximum recommended continuous service temperature is 390°F. Service temperatures exceeding 390°F will be detrimental to the coating. Applications

requiring operating temperatures up to the 500°F
safe limit for TruZinc Steel should be specified without the resin film.
1 9 General Corrosion Characteristics 
The TruZinc Plus coating does not improve the general corrosion characteristics of TruZinc Steel except as described in section 1.0. The resin coating has been tested to 1000 hours of UV exposure with no effect on appearance.
1 10 Product Mixing 
TruZinc Steel and TruZinc Plus Steel should not be mixed in adjacent areas on the same building. The different surface finishes, both in the new and weathered conditions, will result in a contrasting appearance, which may be objectionable.
1 11 Visual Reflectivity 
TruZinc Plus Steel reflectivity is similar to standard TruZinc Steel.
1 12 Electrical Conductivity 
The resin film applied to TruZinc Steel can potentially cause an insulating effect between panels in electrical appliance applications. The insulating effect would normally be overcome with welding or mechanical fastening of components. Manufacturers should be advised to ensure products are adequately grounded.

Inhalation of metal dust and fume may result from further processing by the user, particularly during welding, burning, grinding and machining activities. These potential health hazards should be evaluated by the user. A non-metallic passivation treatment is normally applied based upon customer/end use criteria. These non- metallic coatings may contain hazardous substances of varying amounts. During processing, substances of varying chemical composition and quantity may be generated by the surface passivant. MSDS information regarding the surface passivant shall be supplied to the user upon request.
Carcinogenity:
Certain chromium and nickel compounds as well as organic compounds found in various coating materials have been listed as carcinogens by the NTP, IARC, or OSHA.
Medical Conditions Aggravated by Long Term Exposure:
Individuals with chronic respiratory disorders (i.e., asthma, chronic bronchitis, emphysema, etc.) may be adversely affected by any fume or airborne particulate matter exposure.
Chronic Effects:
Chronic inhalation concentrations of iron oxide fumes or dusts may lead to a benign pneumoconiosis (siderosis). Inhalation of high concentrations of ferric oxide may possibly enhance the risk of lung cancer development in workers exposed to pulmonary carcinogens. Chronic inhalation concentrations of aluminum fumes or dusts may lead to a fibrotic lung condition known as Shaver.s disease; however, evidence for this is not conclusive since affected workers were exposed to other substances (silica) as well. The inhalation of high concentrations of dust from manganese, copper, lead and/or zinc in the respirable particle size range can cause an influenza- like illness termed metal fume fever. Typical symptoms last 12 to 48 hours and are characterized by metallic taste in mouth, dryness and irritation of the throat, followed by weakness, muscle pain, fever and chills. Continuous exposures to high concentrations of manganese can cause central nervous system disorders and .manganese pneumonia.. Fibrosis of lung tissue from manganese exposure has also been reported for products containing manganese only. Overexposure to

aluminum dust can cause shortness of breath. Long term inhalation exposure to high concentrations (overexposure) to pneumoconiotic agents may act synergistically with inhalation of oxides, fumes or dusts of this product to cause toxic effects. Prolonged or repeated contact with unprotected skin may result in skin irritation. Torching or burning operations on steel products with oil or organic coating may produce emissions which can be irritating to the eyes and respiratory tract.
Precautionary Statement:
Inhalation of metal dust and fume may result from further processing by the user, particularly during welding, burning, grinding and machining activities. These potential health hazards should be evaluated by the user.

TECHNICAL BULLETIN

Do Not Mix Paint and Mill Applied Coating Systems

1 0 Introduction
Due to the chemical and physical variability within certain paint and coating systems and slight process equipment changes from one production run to another, there are some products whose appearance may not be the same from order to order. This technical bulletin describes those items Steelscape does not guarantee as reproducible and guidelines for avoiding mixed orders on jobsites.

1 1 Metallic/Mica Paints
The metallic/mica family of paints is inherently variable in appearance due to not only the physical shape of
the pigment particles but also their behavior during the application process. The individual pigment particles are flat in nature allowing for light to reflect from them at various angles. They are also typically larger in size than non-metallic pigments. The specific orientation of these pigment particles affects how
the final paint system appears visually to the human eye. The exact size and orientation of these pigment particles cannot be completely controlled during the paint manufacturing process, thus each paint batch of metallic/mica paint, even though the same color may have a slight visual difference.

When the paint is applied during the coil coating process, the final directional orientation of these pigments cannot be controlled. This results in slight visual variations from one production run to
another, even if the same batch of paint is used. This phenomenon is also responsible for the slight color shift observed when viewing a metallic/mica painted panel in the coil rolling direction versus perpendicular to coil rolling direction. Steelscape does not accept responsibility for material appearance when the architectural design requires panels to be offset (i.e. perpendicular) from adjoining panels, resulting in visual differential in color and or reflectivity.

It is important that the end user does not rotate panels in the cases of symmetrical roll form patterns to avoid obvious color and light differential within the structure. The use of directional arrow branding on the bottom side of metallic material is highly recommended.

1 2 Print-coat Paint Systems (including Steelscape Prints®)
Print-coat paint systems consist of a base coat color
and then a pattern coat of a different color over the top, which allows multiple colors to be visible on the finished product. Order to order variability in this process originates from several sources.

Print Roll Speed: The patterned roll used to create the print effect must be moving as close to the same speed at the coil strip during production. Although every measure is taken to align these two speeds there are slight differences from one production run to another which may result in slight pattern differences.

Paint Viscosity: The viscosity of the paint being used for the print portion of the order will vary slightly from order to order and paint batch to paint batch. The viscosity of the paint on the print roll will affect the look of the final pattern; often resulting in a “lighter” or “heavier” pattern.

Print Roll Pressure: For the pattern coat to transfer from the print roll to the coil strip pressure is applied between the two. The amount of pressure controls the amount of paint film applied to the strip as well as the look of the pattern. This pressure will fluctuate slightly between production runs resulting in slightly different pattern appearances.

1 3 Vintage® and Eternal Collection®
The Vintage and Eternal Collection are inherently variable in appearance due to the coatings’ composition and application process. The make- up of these specialized coatings, while guaranteed
within an approved color range, cannot be completely controlled during the paint manufacturing process. In addition, these coatings are semi-transparent and final appearance is influenced by the substrate surface, which can also vary between batches. As such, each coating batch may have a slight visual difference.

These slight visual variations from one production run to another can occur even if the same batch

of the coating is used. This phenomenon is also responsible for the slight color shift observed when viewing a coated panel in the coil rolling direction versus perpendicular to coil rolling direction (“flop”). Steelscape does not accept responsibility for material appearance when the architectural design requires panels to be offset (i.e. perpendicular) from adjoining panels, resulting in visual differential in color and or reflectivity.

It is important that the end user does not rotate panels in the cases of symmetrical roll form patterns to avoid obvious color and light differential within the structure.

1 4 Rawhide and Textured Paint Systems
The chemistry and ingredients that create the textured appearance in the Rawhide coating, and other textured paint systems, can vary between paint batches. In addition, the look and density of the textured surface is influenced by slight changes in the application process and film thickness. For these reasons care should be taken not to mix batches of Rawhide or other textured paint systems.

1 5 Visual Only Paint Colors
The color of some paint systems cannot be measured electronically due to pigmentation or gloss. These are often very bright, saturated colors or very high gloss paint systems. Metallics, micas and other special effect pigments would also be included in this category. When a color cannot be measured electronically against a standard it is assessed visually by a person using a color light booth. This human factor along with the nature of the paint formulation can result in batch to batch color variation and batches should not be mixed on jobsites.

1 6 ReziBond®, ZINCALUME® Plus, TruZinc® Plus and Other Mill Applied Resins and Coatings Resins and coating systems applied on the metallic coating mill have inherent batch to batch variability
for several reasons. The application process on the mill has limitations that can result in a wider range of coating weights and film thicknesses as compared to a paint line, this in turn can result in color and flow variation between production batches. Mill applied systems are not color controlled. The majority of mill

applied coatings and resins are either transparent, or semi-transparent and are therefore influenced by the appearance of the underlying metallic coated substrate, which can vary between batches.

2 0 Guidelines for Avoiding Mixed Orders on Jobs
Inventory and order size are critical for ensuring that mixed batches of variable painted and/or coated product do not get used at a jobsite. If the paint system or specialized coating is a standard or stock item, order large quantities at a time; this will allow for fewer batches in inventory and reduce the risk of mixed orders on a job.
If the item is a custom color or print requiring established minimum linear feet, order slightly more linear feet than the job requires. This will allow any damaged or defective material to be replaced from the same production run.

If it is necessary to use more than one order of a metallic/mica, print-coat or specialized coating on a job, compare the different available batches carefully; some batches may be a better match than others.
Also, using different batches on trim, accessories or on separated portions of a building may not be visually objectionable.

If a project cannot be completed without ordering additional material, it is imperative that Steelscape be notified of the situation and told which previous order needs to be matched. Although Steelscape will not guarantee a match on metallics/micas, print-coats or specialized coatings, every effort will be made to duplicate the desired color as closely as possible.

Steelscape strongly recommends the use of branded, directional arrows on metallic, micas, Vintage®, Eternal Collection® and TruzGuard® coated coils.

STEELSCAPE VALUE-ADD PROCESSES
Steelscape values innovation and progress. In every indus- try, there are vast opportunities for advancement, growth and overall improvement both in products and processes. However, in most cases, these opportunities do not come easily. It takes time, effort and dedication to find and devel- op these opportunities into something that is attainable and real. Steelscape, in an effort to lead the steel industry in this innovative quest, devotes resources to doing just that. And the result over the past several years has been a host of new products and processes that Steelscape is now offering to you.

The following pages outline some of the many additional processes that Steelscape has to offer. While not every new de- velopment is listed in the section, it should provide you with a brief look at some of the work Steelscape has been doing over the past few years. We highlight our value-add processes such as slitting, embossing, cut-to-length and mill applied coatings.

To learn more about Steelscape’s value-added processes, contact a Steelscape Sales Representative. And, as always, any suggestions for new products or processes are always welcome!

PRODUCT OPTIONS
Skin Passing
Skin-passing is a critical step to achieving superior surface quality, especially for painted steel products. It is important to define whether a product should be skin-passed when placing an order.

Recommendations for skin-passing are as follows:
All painted products must be skin-passed. Any question as to skin-passing necessity should be referred to our Sales or Technical Sales Dept. prior to placing an order.
Resin coated products should not be skin-passed as it is very difficult to measure the resin coating thickness
Skin-passing produces an extra smooth bare product and is especially beneficial for painted products.
Chemical-Treatment & Oiling
Chemical-treatment and oiling are also critical steps in the metallic coating process. Both processes lengthen finished product shelf life and help to prevent field rejections due to rust. Oil is important in cases where resin is not available and self-lubricating surface characteristics are desired. It is important to specify whether a product should be chemically- treated and/or oiled when placing an order.

Recommendations when chem-treating or oiling are as follows:
Any questions regarding oiling or chemical-treatment necessity including RoHs compliances should be referred to our Technical Sales Department. We have several options available.
All resin-coated products (TruZinc® Plus and ZINCALUME® Plus) should not be oiled. Oiling is unnecessary and makes the resin-coated surface too slick.
Some bare, chemically-treated (non-resin) products require light to medium oiling so adequate lubricating properties are achieved for downstream processing.
Bare, paint line feed product not painting at Steelscape, may require chemical-treatment to prevent storage and transportation corrosion, consult with our Technical Sales Department.
All other bare products should be chemically-treated.

Theoretical Minimum Weight
Steelscape provides ZINCALUME® and TruZinc® Steel products on both an actual weight and TMW (theoretical minimum weight) basis. Many of our customers sell their products on a lineal footage basis and it makes sense to purchase the same way. TMW pricing permits customers to pay for the lineal feet of coated steel in a particular coil (or order). If the steel is slightly thicker than the minimum dimensions ordered customers do not pay for the excess. Customers are charged only for the lineal feet received.
There is a small extra charge for the added feature of TMW pricing and customers should contact your Steelscape Sales Representative for details.

For customers buying and selling steel on an actual weight basis our standard pricing uses the actual weight of each

coil (or order) to calculate the invoiced price. Steelscape calculates the price of TMW products as follows:

TruZinc® Steel
ρst = density of steel and zinc coating = 0.2833 lb/in3
χ = ordered width of steel (inches)
τ = ordered thickness of steel (inches)
δ = actual lineal feet of steel (feet)
Theoretical Minimum Weight (lb) = ρst • χ• τ• δ• 12 Gauge x Width x 12 x .2833 = TMW
Example: ordered width = 48", ordered thickness = 0.019", actual lineal feet in coil = 5,500
TMW = 0.2833 • 48 • 0.019 • 5500 • 12 = 17,052.4 lb

ZINCALUME® Steel
ρst = density of steel = 0.2833 lb/in3
ρZINCALUME = density of zinc-aluminum coating = 0.1355 lb/in3
β = thickness of ZINCALUME AZ50 coating = 0.0016"
χ = ordered width of steel (inches)
τ = ordered thickness of steel (inches)
δ = actual lineal feet of steel (feet)
Theoretical Minimum Weight (lbs) = [ρst • (τ - β) + (β•
ρZINCALUME)] • χ• δ• 12
example: ordered width = 48", ordered thickness = 0.019", actual lineal feet in coil = 5,500
TMW = [0.2833 • (0.019 - 0.0016) + (0.0016 • 0.1355)] • 48 •
5500 • 12 = 16,293 lb

Resin Coating
Steelscape offers a clear resin coating on ZINCALUME® Steel product called ZINCALUME® Plus Steel. We also offer a resin coated TruZinc® Steel, TruZinc® Plus. The resin coating is water-based and is 0.031 to 0.060 mils thick.
The resin coating is applied in-line to both top and bottom surface. It is formulated to resist finger printing and scuffing during product handling in addition to improving resistance to wet-stack stains occurring during transport and storage.
ZINCALUME Plus and TruZinc Plus Steel virtually eliminates the need for roll forming lubricants.

Steelscape requests that customers notify them if any adhesion properties are required of either ZINCALUME Plus or TruZinc Plus steel products at the time of placing an order. Depending on the adhesion properties required, a different resin system may need to be applied.

Several other, specialty resins are available, including tinted products. Please inquire with your Steelscape Sales Representative for additional information.

Fluting vs. Non-Fluting Steel

APRIL 2015 I Rev 1

TECHNICAL BULLETIN

Guidelines for clarification on fluting vs non-fluting steel

1 0 Introduction 
The terms fluting, non-fluting, or fluting hazard are properties often used when discussing steel sheet. This technical bulletin will define fluting and explain why it occurs and the processing capabilities of Steelscape.

1 1 Definition
Fluting can be defined as follows:

Visible line markings that run perpendicular to the forming direction and sometimes appear on the surface of flat rolled low carbon steel products during forming of cylindrical parts:

Fluting lines in formed sample

It is a naturally occurring characteristic of annealed low-carbon steel and is influenced by the steel chemistry, cold-reduction practices and annealing cycles. It is associated with material that has an upper and lower yield point, or yield point elongation (YPE) and may also be referred to as Luder Lines, stretcher strain, or discontinuous/non-uniform yielding.

Product that does not exhibit these lines when formed is usually called non-fluting and is likely related to tension-leveling and/or temper passing practices after annealing.

1 2 Controlling Fluting During Coil Production Fluting can be eliminated or minimized depending on steel chemistry and processing equipment capability. Production lines with high load temper rolling or stretcher/tension leveling capabilities can produce
a non-fluting material. However, the elimination of fluting is often only temporary, and will re-appear as the steel ages.

Steelscape has the ability to skin pass product on both the TruZinc® and ZINCALUME® lines. If the skin pass mill is used the resulting product will be non-fluting for a period of time. All paint line feed coils are skin passed for surface smoothness, but the paint line process accelerates the aging of the steel and therefore
fluting may return. For this reason, Steelscape CANNOT guarantee non-fluting on painted product. The only remedy available at Steelscape is to tension level the painted product after painting. However, like using the skin pass mill, the non-fluting characteristic is temporary.

1 3 How to Order Fluting/Non-Fluting Product While skin passing of non-painted, bare material is not standard, it can be requested if non-fluting is required. There are several end uses that automatically trigger this process. It is important when non-fluting material is required for bare product that it be included on the purchase order and, where applicable, one of the end uses below be designated;
HVAC
Cornerbead-Bullnose
Cornerbead
Piping-Spiral
Piping-Chimney
Piping-Furnace
Track-Garage Door
Flashing-Bird stop (curved)
Rainwater Goods
Ductwork-Die stamped

As already mentioned, Steelscape cannot guarantee non-fluting on painted product without the additional tension leveling or extension process, which is only offered on the slitter at the Rancho Cucamonga, CA location. If painted, non-fluting material is required, the requirement MUST be included on the purchase order and reviewed with both the Steelscape Sales Representative and Technical Services. Additional processing charges may be incurred.

Bare product ordered as non-fluting or painted product subsequently tension leveled for non-fluting should be formed into final parts within 90 days of receipt

FINISHED MATERIAL - RECEIPT & INSPECTION
Once received, the customer is responsible for unloading all material delivered from Steelscape and inspecting the
material for visible damage. The material needs to be stored in a covered/enclosed space to protect the metal from inclement weather, water damage and/or condensation.

Prior to unloading any material with visible damage, the customer must notify the carrier’s representative of the damage and note the damage as such on the delivery receipt.

If the material received does not meet the specifications on the packing list, the customer must notify the Steelscape Customer Service Representative immediately. At such time, the issue can be investigated and remedied.

If the quantity of material received by the customer is less than the quantity invoiced or if material received appears damaged in transit, the customer shall give written notice to the agent of the delivering carrier for verification of the
shortage or damage. The customer will send copy of the same to Steelscape in addition to the receiving records.

Should the customer fail to notify Steelscape promptly of any issues related to damage upon receipt and/or non-
conformance of the material, the material will be considered to have been received in good condition and as ordered. The material will also be considered delivered in accordance with the packing list/shipping documents.

Table 1: Claims Reasons and Claim Limitations

* See following details for specific limitations

Specific Claim Reasons:
Underweight coils – Steelscape’s definition of coil weights is as follows:
Underweight coils shall not comprise more than 20% of an order without customer approval. If Steelscape ships underweight coils in excess of 20% of an order, a claim for underweight coils may be considered.
For Bare Product, where no minimum coil weight is specified, underweight coils are those coils weighing less than 75% of the specified maximum coil weight. Coils weighing more than 75% of the specified maximum coil weight will be considered fit for purpose.
For Painted Product, where no minimum coil weight is specified, underweight coils are those coils weighing less than 50% of the specified maximum coil weight. Coils weighing greater than 50% of the specified maximum coil weight will be considered fit for purpose.

Embossed Coils
Steelscape will not accept claims for embossed difference in appearance when material is mixed by customer.

Steelscape embossed stucco pattern creates peaks and valleys on the embossed strip. The standard orientation for Steelscape embossed product is peaks up on the topside of the strip. There will be differences in appearance in bare embossed panels when viewing two panels side by side, with opposite sides showing (peaks up/top vs. peaks down/
bottom). Steelscape will not accept claims for this difference in the appearance when panels are processed or installed with panels’ peaks up vs. peaks down by customer.

Painted embossed material can show color variation in the panels if the directionality is reversed panel to panel. This is due to the way light reflects off the peaks and valleys of the embossed surface. This is especially common on higher
gloss paint systems. Steelscape will not accept claims where the panels have been processed or installed reverse direction panel to panel by customer.

Steelscape guarantees all embossed product supplied will not have edge wave greater than fifteen (15) I units. When customer requirements are more stringent than fifteen (15) I units, Steelscape will provide product, as agreed. This agreement must be in writing and must be obtained prior to the order acceptance. When Steelscape provides a product that exhibits edge wave greater than either the agreed
standard or (15) I units, and the product is unsuitable for the designated end use, Steelscape will consider claims for edge wave.

Water Damage
Steelscape will consider claims for water damage when the claims are submitted within thirty (30) days of receipt of product. Any material received wet upon delivery MUST be noted on the receiver documents and acknowledged by the delivering agent. This must be submitted immediately to Steelscape for review. Any material not noted as damaged or wet, will be considered accepted as prime. Examples
of water damage may include; wet cores, visible water or condensation on the inside of packaging, positive moisture tag indicator, visible corrosion (white or black rust on bare product), raised or rough texture of painted surface, and water staining (including yellowish discoloration on resin product).

Storing coils or panels in a manner where they become unprotected from water ingress and condensation will negate Steelscape’s responsibility with respect to water damage claims. Where customers order packaging options that Steelscape considers inadequate for the product, and Steelscape forewarns said customer in writing to that end, Steelscape’s liability for water damage will be negated.

Surface Condition
The production of coil by the hot dip, metal coating process naturally leads to the formation of some surface imperfections on the product. These imperfections, while not adversely affecting product life, may cause problems
when the material is to be post-painted on a coil coating line. Therefore, Steelscape does not recommend the use of non skin-passed product in coil painting applications.

Where skin-passed product is ordered, Steelscape will consider claims for surface imperfections that render the product unsuitable for organic coil coating processes. If coil is ordered as non skin-passed, and subsequently used in organic coil coating, Steelscape will not accept claims for surface imperfections that could reasonably be considered to be removed by the skin-passing operation.

Steelscape will not accept claim for bare or painted hot dip coils with light surface dross as this is a normal part of the metallic coating process.

Flatness
Steelscape will provide material conforming to ASTM standard A924/A924M. When customer requirements demand a product that exceeds these standards, Steelscape must agree, in writing, to provide the material to the customer requirements. Where product does not meet either the ASTM standard or the written undertaking of Steelscape, claims for shape defects will be considered.

Edge Wave
Steelscape guarantees all product supplied will have edge wave less than fifteen (15) I units as defined by ASTM standard A924/A924M. When customer requirements are more stringent than the aforementioned standard, Steelscape will provide product, as agreed. This agreement must be in

writing and must be obtained prior to the order acceptance. When Steelscape provides a product that exhibits edge wave greater than either the agreed standard or A924/A924M, and the product is unsuitable for the designated end use, Steelscape will consider claims for edge wave.

Transport Damage
Claims for transit damage on rail car shipments will only be considered if submitted within fourteen (14) days of the material being available for unloading. Full details of the damage and photographs of the material in the rail cars, along with the rail car number, must be provided with the claim submission. Claims for transit damage on material received by truck should be forwarded to Steelscape immediately upon receipt of the product. All other claims
for transit damage will be accepted within thirty (30) days of receipt of the material.

Handling Damage
Claims for a product that exhibits handling damage will be accepted for up to thirty (30) days from receipt of the
material. Claims must be accompanied by photographs of the damaged product with the Steelscape packaging in place.

Paint Attributes
Steelscape’s painted products will be supplied free from defects or imperfections that detract from the performance or aesthetic value of the product. Painted products will comply with the following standards:

Gloss	To paint vendor’s specification	
Hardness	To paint vendor’s specification	
Film Thickness	To paint vendor’s specification	
Reverse impact	To paint vendor’s specification	
Color	No more than ± 0.5 units on L, A, or B scales from the supplied standard.	
Steelscape may supply product within tighter specifications, but only when there is prior written agreement from Steelscape to provide such a product. Claims regarding quality concerns with painted products will be accepted
for consideration only when the product falls outside these parameters.

Width
Our products will be within width tolerances as defined in ASTM standard A924/A924M.

Thickness
Steelscape’s products will be within the ASTM Full Restricted Tolerances - 1" Minimum Edge Distance, as defined
in ASTM standard A924/A924M (table shown below). However, Steelscape will provide our product to a tighter thickness tolerance if agreement to provide this product is acknowledged in writing prior to order acceptance by a Steelscape Technical Service Engineer.

	Thickness (Inches)	
Width (Inches)	.010 - .023	>.023 - .045	
MINIMUM	Minimum Tolerances - All Plus	
> 0 - 32	0.003	0.004	
> 32 - 40	0.003	0.004	
> 40 - 54	0.003	0.004	
NOMINAL	Nominal Tolerances - Plus and Minus	
> 0 - 32	0.002	0.002	
> 32 - 40	0.002	0.002	
> 40 - 54	0.002	0.002	

Thickness is measured on the coated sheet and includes the metallic- coating thickness. Thickness is measured at any point on the sheet not less than 1 inch from a side edge, per ASTM 924-16a, Table 2.

Customers should inquire about any application requiring improved (tighter) tolerances for performance reasons.

Processing Charges
Steelscape’s liability shall be limited to the purchase price of the defective material. No other costs associated with the defect will be reimbursed by Steelscape.

Field Failure Claims
Steelscape will consider each field failure claim on an individual basis. Where the product failure is clearly caused by product defects, Steelscape will, at its own option, replace or repair defective product where failure occurs after installation. Replacement cost will be limited to the value of the material only. Any other costs or contingencies will not be considered. This includes, but is not limited to, transport fees, material forming, job installation, removal of defective product, late charges for the job, equipment rental, idle person-hours, or other installation or administrative costs.

Secondary Product
All secondary products sold by Steelscape are sold on an “as is” basis, with no warranty expressed or implied. No quality claims will be accepted on secondary product.

Other Claim Reasons
Steelscape will consider other reasons for quality concerns on an individual basis. Should these occur, the customer must contact either their Account Manager, Customer Service Representative or Technical Services.

Steelscape Claim Responses
Steelscape will respond to the customer within thirty (30) calendar days from the date complete claims information is provided by the customer to the Steelscape Technical Service Engineer. Steelscape’s response may include one of the following:
Acceptance of the rejection and instructions for material disposition.
Denial of the rejection with adequate explanation for the

denial.
Recommendations for further processing at the customer’s facility for purposes of working through the defective material.
Instructions for the return of the material in question to Steelscape. Some material may be usable with additional processing. Once the material has been reprocessed
and the issue resolved, the material will be returned to the customer. Authorized returns to Steelscape must be completed within 120 days of claim acceptance.
Request for an extension if acceptance or denial cannot be determined within the thirty (30) calendar days. A request for extension will include a reason and the specific timeline for a final response.

The customer will have the opportunity to appeal any denied claim for fourteen (14) calendar days after written denial
is provided by Steelscape. All accounting transactions related to the claim will be held until such time that the final disposition of the claim has been made and agreed to by both parties.

Tagged Defect
Steelscape’s products may contain a tagged or marked defect. The tags define the start and end point of such a defect. Steelscape will not accept claims on this material when the defect falls within the boundaries of the tags. This defective material can be included in scrap reconciliation with Steelscape or reduced from the price of the coil prior to invoicing. Consideration will be given to any defects outside

the tagged area.
Running Minimum Amount of Defect
Wherever possible and practical Steelscape requests that the customer try to process a minimum of 200 ft. of the product before filing a claim. This is due to the fact that some defects may clear up within 200 ft. However, where the defect is obviously evident throughout the coil, no such processing is required.

Segregation and Protection of Claim Coils
Steelscape requires customers to have the defective coils readily available for inspection at a mutually arranged time. The coils may require an inspection on a recoiler unit or rolled out in a safe manner to be inspected by Steelscape representatives. Steelscape requires customers to provide adequate protection of all claim coils to prevent generation of further defects. Steelscape may reduce the claim amount by the amount of any additional induced losses due to inadequate protection.

NOTE: Any unauthorized or unidentified deductions taken by a customer before a claim is disposed of, approved by Steelscape, and settled shall constitute nonpayment with subsequent consequences.
Consequences may include, but not limited to, implementation by Steelscape of a credit hold, shipping hold, and/or loss of discount privileges.

TMW (Theoretical Minimum Weight): Pricing practice that effectively charges per square or lineal foot of material as opposed to by weight. This practice is particularly useful for customers that sell products by the lineal foot and are concerned about yield loss due to variation in the gauge (thickness) of purchased steel. Refer to the SOM section for a complete commercial definition of Steelscape’s TMW price policy.

Toll Processed Steel (Also Customer-Owned or Double Bill): Steel that is provided by customers to Steelscape for processing. Offer includes painting, slitting, embossing or cut-to-length. This is a core business for Steelscape.

Transit Damage: Damage incurred to a coil during loading, unloading, and/or transport.

Underweight Coil: A coil that fails to meet the customer’s minimum weight requirements.

Urethane Paint: Urethane is the term for the chemical linkage between an isocyanate and a hydroxyl group. A urethane can be a polyester urethane (polyurethane), an acrylic urethane or an epoxy urethane. Most coil urethanes are polyester urethanes usually used in primer applications. Urethanes are characterized by having a good flexibility to hardness ratio and a good chemical resistance.

Ultimate Tensile Strength: Typically, the breaking strength or highest strength achieved for materials.

Yield Strength: Yield strength represents the stress at which materials transition from elastic to plastic deformation.
Once a material has been loaded past its yield point, it is permanently deformed.

Water Damage: Corrosion of the product due to the ingress of water or moisture.

ASTM SPECIFICATIONS
Organized in 1898, ASTM has grown into one of the largest voluntary standards development systems in the world.
ASTM is a not-for-profit organization which provides a forum for producers, users, ultimate consumers, and those
having a general interest (representatives of government and academia) to meet on common ground and write standards for materials, products, systems and services.

ASTM standards are developed and used voluntarily. Standards become legally binding only when a government body references them in regulations, or when they are cited in a contract. Any item that is produced and marked as conforming to an ASTM standard must meet all applicable requirements of that standard.

ASTM standards are used by thousands of individuals, companies and agencies. Purchasers and sellers incorporate standards into contracts architects and designers use them in plans; government agencies reference them in codes, regulations and laws; and many others refer to the standards for guidance. Steelscape products are manufactured in accordance with the most recent versions of the respective ASTM standards as listed below:

ZINCALUME® products ASTM A792 TruZinc® products ASTM A653
Cold Rolled ASTM A568
Metallic Coated Steel Sheet ASTM A924

Steelscape produces to many other ASTM standards as required by end use or customer request. For more information, please contact your Steelscape Sales Representative.

Due to ASTM membership requirements and copyright law, Steelscape may not provide copies of ASTM standards.
