Steel Sheet Thickness Tolerances. ASTM International Committees A01 on Steel, Stainless Steel and Related Alloys and A05 on Metallic-Coated Iron and Steel Products recently approved revisions to two standards that clarify the thickness tolerances for both uncoated and coated steel sheet products.
One specific problem with this code requirement is the indication of "(No. 26 galvanized steel)." If using the U.S. Standard Gauge to determine metal gauge from metal thicknesses, 0.019 inch correlates to a 26-gauge metal thickness. However, if using B & S (Brown and Sharpe) gauge conversions, 26 gauge only is 0.0159 of an inch thick.
