GALVANIzED SHEET DECIMAL AND NOMINAL THICKNESS EQUIVALENT (inch) RECOMMENDED MINIMUM THICKNESS EQUIVALENT* (inch) For SI units: 1 inch = 25.4 mm * The thickness of the sheets set forth in the code correspond to the thickness shown under these columns. They are the approximate minimum thicknesses and are based on the following references: Carbon Sheet Steel Thickness inch (1.803 mm) and over: ASTM A 568, Table 3, Thickness Tolerances of Hot-Rolled Sheet (Carbon Steel). Carbon Sheet Steel Thickness less than inch (1.803 mm): ASTM A 568, Table 23, Thickness Tolerances of Cold-Rolled Sheet (Carbon and High-Strength Low Alloy). Galvanized Sheet Steel All thicknesses: ASTM A 653, Table 4, Thickness Tolerances of Hot-Dip Galvanized Sheet. Minimum thickness is the difference between the thickness equivalent of each gauge and the maximum negative tolerance for the widest rolled width CALIFORNIA MECHANICAL CODE 343
