The 2018 and 2021 IBC both reference AISI S240 and S220 for Structural and Nonstructural Cold-Formed Steel Framing. This specification currently references only ASTM C955 and C654 which have not been fully reference by the IBC since 2012. The intent of these revisions is to update the ASTM standard by adding AISI S240 and S220 to be in sync with the newest IBC versions, as they are now being used by the industry and have been adopted by many states and local municipalities.
