How Thick Is 20 Gauge Sheet Metal

A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material.

How thick is 20 gauge sheet metal. In most of the world sheet metal thickness is consistently specified in millimeters. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. This is known as the manufacturers standard. Gague are used to specify the thickness of a metal sheet.

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. The larger the gauge number the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.

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. As the gauge number increases the material thickness decreases. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge.
