Gauge Definition Sheet Metal

Metal decking is most commonly 16 18 20 and 22 gauge in thickness.

Gauge definition sheet metal. So inversely the smaller the gauge number the thicker the metal. The larger the gauge number the thinner the metal. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. Unit of thickness of a metal sheet or wire.

As the gauge number increases the thickness drops by 10 percent for example a 12 gauge sheet is 2 732 millimeters thick and a 13 gauge sheet is 2 391 millimeters thick. The larger the gauge number the thinner the metal. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material.

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. How gauge thickness works. As the gauge number increases the material thickness decreases. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

A measure of thickness for sheet metal. In most of the world sheet metal thickness is consistently specified in millimeters. Why gauge thickness matters. 1 for sheet metal a retrogressive scale higher numbers mean lower thickness that starts with 10 gauge representing a thickness of 3 416 millimeters or 0 1345 inches.
