U.S.S. Gauge
A gauge system used for carbon steels but not appropriate for stainless steels where thickness is specified in decimals. However, salesperson should always question customer when unsure as to whether U.S.S. or decimal is being specified. For example, 16 gauge for U.S.S. is .058” not .016”. U.S.S. does not stand for Ulbrich Stainless Steel.
