Published by the CISC since 1967, the Handbook of Steel Construction is the standard reference for the design and detailing of structural steel in Canada. The 12th Edition has been updated to reflect changes to CSA S16:19, Design of steel structures, and the steel section data. It is intended to be used in conjunction with the National Building Code of Canada (NBCC) 2020. Member design tables are based on steel grades ASTM A992, A572 Grade 50, A913 Grade 65, A500 Grade C and CSA G40.21-350W.
