MATERIAL SPECIFICATION

2W/3W Composite Floor Decks are manufactured using BHP Z275 G300 galvanized steel sheets. Z275 refers to an average zinc coating of 275 g/m2 (total both sides, triple spot method), meeting the specifications of ASTM A525 G90; G300 to a minimum yield strength of 300 MPa, surpassing the specification of ASTM A446 Grade C. If new material specification numbers issued by the ASTM in 1994 for galvanized products are used, BHP Z275 G300 galvanized steel sheets meet or surpass ASTM A653 SQ Grade 40 (275) with coating G90.
