AISC Certification Certified Companies

Industry standard quality certification for structural steel fabricators and erectors.

89 certified companies

AISC certification is the gold standard for structural steel fabrication quality in the United States. The certification program verifies that a fabricator has implemented a comprehensive quality management system covering personnel qualifications, welding procedures, material control, shop practices, inspection, and documentation. AISC offers multiple certification categories reflecting different levels of structural complexity: Standard for Building Structures (SBR) covers most commercial and industrial buildings; Intermediate Bridge (IBR) and Advanced Bridge (ABR) cover highway bridge fabrication; Complex Steel Bridge (CPT) addresses the most demanding bridge structures; and Metal Building Systems (MBS) covers pre-engineered metal building fabrication. Specifying an AISC-certified fabricator provides assurance that the shop has been independently audited by AISC Quality Management Company (QMC) and demonstrated compliance with quality standards. You can verify any fabricator's current AISC certification status through the AISC Certified Fabricator search on their website.

AISC Certification FAQ

What are the AISC certification categories?

Key categories include Standard for Building Structures (SBR), Intermediate Bridge (IBR), Advanced Bridge (ABR), Complex Steel Bridge (CPT), Metal Building Systems (MBS), and Steel Erector. Each has progressively more stringent requirements for quality systems, personnel, and capabilities.

Is AISC certification required?

While not legally mandated everywhere, many state DOTs, federal agencies, and project specifications require AISC certification. The International Building Code (IBC) references AISC 360 for structural steel design, and most engineers specify AISC-certified fabricators.
