Gauge Definition Sheet Metal

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.

Gauge definition sheet metal.

So inversely the smaller the gauge number the thicker the metal. How gauge thickness works. Why gauge thickness matters. A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material.

The larger the gauge number the thinner the metal. Sheet metal gauge size chart gauge or gage sizes are numbers that indicate the thickness of a piece of sheet metal with a higher number referring to a thinner sheet. Metal decking is most commonly 16 18 20 and 22 gauge in thickness. A measure of thickness for sheet metal.

The larger the gauge number the thinner the metal. In most of the world sheet metal thickness is consistently specified in millimeters. 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. Unit of thickness of a metal sheet or wire.

Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. 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.
