What bar sizes are available?
U.S. mills produce stainless steel reinforcement for domestic purposes in the same imperial sizes as conventional black carbon bars -- #3, #4, #5, etc. The nominal bar dimensions presented in ASTM A955 are in imperial inch-pound units as well as the numerically equivalent SI units. The bar designation numbers in ASTM A955 are either labelled as the actual imperial size (#3, #4, #5, etc.) or the “soft metric” version (10M, 13M, 15M, etc.), which are not numerically equivalent but for convenience are rounded whole numbers.
Canadian metric sizes such as 10M, 15M, 20M, etc. that meet the specific CSA G30.18 dimensional requirements are also available from U. S. sources. Stainless steel reinforcement is also available from European mills in a range of sizes that meet the British Standard BS 6744. The British Standards dimensions differ from U.S. and Canadian sizes. Producers should be contacted for the exact sizes available.
