Standard Thickness Steel Sheet

Gague are used to specify the thickness of a metal sheet.

Standard thickness steel sheet.

Standard steel in galvanized steel in stainless steel in aluminum brass. The chart below can be used to determine the equivalent sheet thickness in inches or millimeters for a gauge number from the selected gauge size standard. For other materials such as aluminum and brass the thicknesses will be different. Number of gauge approximate thickness in fractions of an inch.

Manufacturers standard gauge for sheet steel is based on an average density of 41 82 lb per square foot per inch thick equivalent to 501 84 pounds per cubic foot 8 038 7 kg m 3.

Inches mm inches mm 26. Gauge is defined differently for ferrous iron based and non ferrous metals e g. Gague ga is a length measurement unit for diameters originating in north america and belongs to the browne sharpe metering system. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.

For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. Thus a 10 gauge steel sheet which has a thickness of 0 1345 inches will weigh 41 82 0 1345 5 625 pounds per square foot. Lastly a standard exists for zinc in which a higher gauge number indicates a thicker sheet. 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.

The gauge number 18 holds no relevance to the actual measurements. As the gauge number increases the material thickness decreases. We stock steel sheet and plate in 36 48 and 60 widths and in 96 120 and 144 lengths. Standard practice for using hand micrometers to measure the thickness of uncoated steel sheet and nonmetallic and metallic coated steel sheet a1087 a1087m 16 standard practice for using hand calipers to measure the width of steel sheet.
