Standard specification for steel sheet hot rolled carbon commercial structural and high strength low alloy and ultra high strength produced by twin roll casting process.

Standard thickness steel sheet.

Lastly a standard exists for zinc in which a higher gauge number indicates a thicker sheet. Gauges are neither standard nor metric and the values are independent of those measurement systems. For other materials such as aluminum and brass the thicknesses will be different. A1039 a1039m 20.

Sheets ordered by gauge weight or thickness are subject to standard thickness and weight tolerances. Heavier or 0037 inch thicker than the weight or thickness of the corresponding u s. Standard specification for steel sheet and strip heavy thickness coils alloy drawing steel and structural steel hot rolled. For the purpose of securing uniformity the following is established as the only standard gauge for sheet and plate iron and steel in the united states of america namely.

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. This is known as the manufacturers standard gage for sheet steel. For example 18 gauge steel according to a gauge conversion chart is 0. Thus a 10 gauge steel sheet which has a thickness of 0 1345 inches will weigh.

When working with sheet metal the term gauge is often used. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. Standard gauge number regardless. Cold rolled steel sheet is essentially hot rolled steel that has been further processed to increase its strength and strength to weight ratio.
