How this directory is built. Every listing is compiled from the fabricator’s own public website (or claimed by the company itself) and links back to it. We do not republish AISC’s Find-a-Certified-Company database or any other protected directory, and this site is not endorsed by or affiliated with AISC. Where a company states a certification on its own site we note it, but certification status changes — verify current AISC certification, capabilities, and contact details directly with the company and with AISC before you rely on it. Reference aid, not procurement advice.
