AISI updates CFS framing design standard

The American Iron and Steel Institute (AISI) has updated AISI S201, North American Standard for Cold-Formed Steel Framing – Product Data, it was announced today. AISI S201-17 supersedes the previous edition, AISI S201-12. The standard has been approved by the American National Standards Institute (ANSI) and is available for downloading free of charge at www.aisistandards.org.

“This new edition is largely the same as the 2012 edition; changes were simply made to update referenced documents and to make the scope of the standard consistent with other AISI cold-formed steel framing standards,” said Jay Larson, P.E., F.ASCE, Managing Director, Construction Technical Program. “The standard is intended to establish and encourage the production and use of standardized products in the United States, Canada and Mexico. The components covered in AISI S201-17 include C-shape studs, joists, track, U-channels, furring channels and angles.”
