Sets out requirements for the design of cold-formed stainless steel structural members. Steels for use with this Standard include those specified by a wide range of international Standards. Members may be shaped from annealed or temper-rolled sheet, strip, plate or flat bar.

This Standard sets out minimum requirements for the design of stainless steel structural members cold-formed to shape from annealed or temper-rolled sheet, strip, plate or flat bar stainless steels used for load-carrying purposes in buildings. It may also be used for structures other than buildings provided appropriate allowances are made for dynamic effects.For the purpose of this Standard, steels with at least 10.5% chromium and up to 1.2% carbon are considered as stainless steels.
