Understanding the Buy Clean California requirements is crucial when furnishing or specifying structural steel for projects. Familiarizing yourself with these standards ensures compliance and supports sustainable practices in construction.

STI Industry-average Non-fabricated EPD


On behalf of our member producers, STI developed an Industry-Average Environmental Product Declaration (EPD) for Unfabricated HSS and related products, as well as partnered with AISC in developing an Industry-Average Fabricated HSS EPD. Both the Unfabricated and Fabricated EPDs can be found below.

View the ASTM standards these industry-average EPDs cover.


STI Member Producers’ Facility-Specific EPDs offer unmatched transparency that sets apart STI member producers’ products from others. Review STI producer members’ complete sustainability story within the facility-specific EPDs below.
