AISI is an accredited consensus organization by the American National Standards Institute (ANSI) for developing American National Standards (ANS). The AISI Committee on Specifications and the Committee on Framing Standards are the consensus committees that follow the American Iron and Steel Institute Procedures for ANSI-Approved Standards for Cold-Formed Steel Design and Construction. The committees welcome any interested groups to participate in their activities. For further information, please contact Helen Chen.
