They are the approximate minimum thicknesses and are based on the following references: Carbon Sheet Steel Thickness 0.071 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 0.071 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. 2013 CALIFORNIA MECHANICAL CODE 343
