Standard steel sheet thickness.

Number of gauge approximate thickness in fractions of an inch. 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. 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. 16 ga crs is 2 5 pounds per square foot.

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. Gauge differs between ferrous iron based metals and nonferrous metals such as aluminum or copper. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.

Offers hot and cold rolled steel sheet and hot and cold rolled steel plate in a broad range of lengths widths gauges alloys and specifications to meet your material requirements. For other materials such as aluminum and brass the thicknesses will be different. 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.
