Codes and Standards The mostly widely adopted model building code in North America is the International Building Code (IBC), available from the International Code Council Store. The primary requirements in the IBC that guide cold-formed steel design and construction have migrated from ASTM reference standards to standards developed and maintained by the American Iron and Steel Institute (AISI). As of the 2018 IBC, the AISI standards are now the primary standards of record for cold-formed steel. AISI Standards Through the end of 2023, AISI was an ANSI consensus standards-writing organization that produced a series of standards that govern cold-formed steel. At the end of 2023, AISI requested the withdrawal of its ANSI accreditation, and its sponsored American National Standards and registered projects were transferred to the Steel Deck Institute. Most notably, the standards produced by AISI include the following (scroll to bottom for free downloads link):
Download these and other cold-formed standards for free at www.buildusingsteel.org. They are available individually or as a bundle that includes all relevant standards for a given time frame. Prior versions are available for jurisdictions that have not yet updated to the 2018 International Building Code. |
AISI S100-16 (S2-20) 2020 edition: North American Specification for the Design of Cold-Formed Steel Structural Members, 2016 Edition with Supplement 1. This standard governs the engineering design of cold-formed steel structures.

AISI S240-20 Announcements
Press Release - June 1,2023
On May 1, 2023, the Cold-Formed Steel Engineers Institute (CFSEI), the steel framing industry’s leading professional design association, moved from its former home with the American Iron and Steel Institute to become part of the SFIA.
Tonnage Reports - 2022
These reports provides buyers and users of cold-formed steel framing in the United States with an industry-wide statistical summary of the volume of steel.
The increased use of wood framing in mid-rise buildings has been accompanied by a growing incidence of major fires that have destroyed these combustible structures both during construction.
SFIA Technical Guide - Release
Technical Guide for Cold‐Formed Steel Framing Products, provides with a comprehensive tool for designing with cold‐formed steel framing members.
