Environmental Product Declarations
Industry-Wide Environmental Product Declarations for Metal Building Systems Products
Environmental Product Declarations (EPDs) disclose the environmental impacts of a product based on the results of a Life Cycle Assessment (LCA), in addition to other useful information. The MBMA EPDs are third-party validated and are ISO compliant. These EPDs can be used by the design community when specifying the use of MBMA Member structural steel and metal panel products.
Primary Structural Steel Frame Components EPD: An assemblage of rigidly connected rafters and columns that support secondary framing members and metal roof and wall panels. Primary frames are built-up using three welded steel plates to form an "I" section. Primary frames may be tapered or straight columns, depending on project needs.
Secondary Structural Steel Frame Components EPD: Cold-formed steel "cee" and "zee" shaped purlins and girts used to span the distance between the primary structural steel framing members to support metal wall and roof panels.
Roll Formed Metal Wall and Roof Panels EPD: Single-skin roll formed metal wall panels (through fastened) and roof panels (standing seam and through fastened). Metal panels formed from aluminum/zinc coated or hot-dip galvanized coils and may be bare steel or painted steel.
