PART 3 EXECUTION

FABRICATION
Fabricate components in accordance with manufacturer’s instructions.

EXAMINATION
Do not begin installation until substrates have been properly prepared.

If substrate preparation is the responsibility of another installer, notify architect of unsatisfactory preparation before proceeding.
STORAGE
Stack the product on wood or metal skids so the product is 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 or between nested panels.
Use under-roof storage whenever possible. If the product must be stored in the open on bare ground, a plastic ground cover should be used under the product to minimize condensation on the sheets from moisture in the soil.
Remove plastic or paper packaging upon arrival, if 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.
Avoid using plastic material for covering. Non-breathing materials should not be used to shroud product because they tend to trap moisture. Use only dry, untreated lumber spacers for block stacking.
Store product at an even temperature above the dew point with adequate air circulation to prevent condensation problems.
INSTALLATION
Install in accordance with manufacturer’s instructions.
General 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 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.
Laying: Sheets should be installed with overlaps away from the weather. End laps on profiled metal roofing should be avoided where possible. End lap of metallic coated 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 metallic coated steel or paint coating. Remove all debris and metal filings as soon as possible.
Fasteners: Placement, Size, Type, Life Expectancy and Compatibility: Responsibility for selection of suitable long-lasting fasteners and sealants rests solely with the Buyer.
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.
Larger 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 Metallic Coated Steel and have a life expectancy comparable with the Metallic Coated Steel panel. Refer to the Galvanic Series to ensure compatibility.
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 metallic coated steel. This may cause and increased rate of corrosion of the steel around the fasteners. Screw manufacturers/suppliers and metallic coated steel manufacturer should be consulted to ensure correct usage.
A clear or tinted clear strippable vinyl film may be applied to the coated metal surface prior to roll forming or fabrication. This protective film should remain on the panel through forming and transit, to be removed immediately before or after installation.
Contact with wet cement should be avoided.
Compatibility of Accessories Including Flashing and Sealants: The mix of dissimilar metals or materials will significantly affect service life. Sealants containing amine or acetic acid should never be used. High quality sealants, such as neutral cure silicones, provide good performance in most applications. Responsibility for selection of suitable long-lasting fasteners and sealants rests solely with the Buyer.
Maintenance Procedures to Contribute to Long Life:
The following roof maintenance should be performed regularly or per warranty requirements:
Check panels, rain gutters, and downspouts to ensure they are clear and allow free drainage of rainwater from the roof. Valley gutters and grates should also be cleaned.
Inspect and clean areas under eaves and wall/soffit areas under overhangs that are not washed by rain.
Remove accumulations of leaves, branches and other debris at ridge caps and in corners.
Check the condition of auxiliary equipment such as air conditioner supports, drains and housings. Any exposed metal susceptible to rust or that which has rusted should be painted with a rust inhibiting coating.
Remove trash thrown on the roof likely to clog drains or cause silt buildup.
Regular cleaning of surfaces, and the removal of accumulated debris such as leaves, dirt, pollution fallout, etc., will help prevent the setting up of localized areas where accelerated corrosion might occur.
Corrosive environments, such as close proximity to saltwater, can be particularly aggressive to metallic coated products. More frequent cleaning and maintenance is required.
CLEAN-UP
After erection, 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 cutting roof and wall sheeting to size with discs, or drilling to fix with fasteners, can create debris which is unsightly and can create localized corrosion and shorten the service life.

Mud and dirt tracked onto the roof panels, and greasy hand and foot prints, can be removed by washing with a cleaner consisting of 1/3 cup mild detergent (e.g. Tide) in one gallon of water applied with a mop or soft broom. The roof should be then 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.
PROTECTION
Protect installed products until completion of project.
Touch-up, repair or replace damaged products before Substantial Completion.
