aisi-s201-17New Version Of AISI S201 Supersedes 2012 Edition

Washington, DC - The American Iron and Steel Institute (AISI) has updated AISI S201, North American Standard for Cold-Formed Steel Framing – Product Data. 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

“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.”

AISI’s codes and standards work is conducted under the Construction Market Council of the Steel Market Development Institute (SMDI), a business unit of AISI, which oversees the industry’s investment in advancing the competitive use of steel by meeting the demands of the marketplace.
