AISI | Steel Specifications, Codes and Standards

Codes and standards are a core competency of AISI's Construction Market Program.

AISI Standards have been adopted by ICC International Building Code 2006 and NFPA 2005-2006 Building Codes:

Supplement 2 to AISI S214-07 (North American Standard for Cold-Formed Steel Framing – Truss Design, 2007 Edition).This supplement was issued in June 2008. It completely replaces Supplement 1 to AISI S214-07, and revises and clarifies provisions related to design responsibilities, loading, quality criteria and bracing for greater consistency with building codes and industry practice. Specifically, the purpose of this supplement is to better harmonize with the provisions desired by involved industry groups, including NCSEA and WTCA, which were initially documented in IBC Proposal S209-07/08.
