Living Building Challenge Red List Chemicals

The Living Building Challenge (LBC) 3.1 standard contains seven imperatives for developing and constructing non-harmful, and ultimately regenerative, buildings and homes. One of these imperatives is “Materials” which in turn contains the “Red List”. Red List chemicals are defined by the LBC as worst in class materials prevalent in the building industry. The LBC requires declaration of Red List substances in concentrations of 100ppm or greater in a finished product.

Steelscape’s metallic coated products, namely ZINCALUME®, TruZinc®, ZINCALUME® Plus and TruZinc® Plus products, comply with the Living Building Challenge material Red List. Please note that while this material complies, it is the responsibility of end-product manufacturers (Steelscape customers) to obtain a Red List Free certification label.

The chemical composition of paint applied to Steelscape’s metallic coated products varies by paint system and manufacturer. For painted product Red List inquiries please contact the Steelscape technical resources team.

For certain projects, Steelscape may obtain high-recycled content feed material based upon customer request. High-recycled content products may contain unintentional trace amounts of Red List materials. However as per Declare Manufacturer’s Guidance, Appendix B: Clarifications, this material is still in adherence to the standard, as Steelscape confirms that for its high recycled content material, no Red List ingredients are intentionally added.

If you have any questions, please contact your Steelscape sales representative, or Steelscape directly at (888) 553-5521 or at productinfo@steelscape.com.

Sincerely,
