AISI Design Standards
The American Iron and Steel Institute represents the North American steel industry and is an ANSI accredited standards writing organization. AISI has two committees working on developing design documents for the sheet steel industry. The Committee on Specifications (COS) is responsible for AISI S100 North American Specification for the Design of Cold-Formed Steel Structural Members. This same document is published for use in Canada as CSA-S136 by the Canadian Standards Association. The other group is the Committee on Framing Standards (COFS) who develop design standards that are more for structural systems incorporating cold-formed steel framing members. Many of the COFS standards have been adopted for use in Canada by reference in CSA-S136.
