Sheet Metal Gauge Thickness Chart

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

Sheet metal gauge thickness chart.

Gauge and weight chart for sheet steel galvanized steel stainless steel aluminum and strip tubing. Sheet metal gauge thickness chart. Processing may include polishing or the applying of protective plastics which will decrease or increase a sheet s thickness respectively. Sheet metal gauge thickness chart 2019 10 24t01 36 33 00 00.

Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. Sheet metal thickness is denoted by gauge sometimes spelled gage which indicates a standard thickness before processing. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. The comparison of different unit systems is shown in the table below.

There is no conversion formula due to the difference between ga. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. When working with sheet metal the term gauge is often used. The larger the number of gauge is the smaller the diameter is.

In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. 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. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Gague are used to specify the thickness of a metal sheet.

The larger the gauge number the thinner the metal. As the gauge number increases the material thickness decreases. A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material. It is also used to indicate thickness after promotion.

Wire gauge is a measure for the size of a wire either in diameter or in cross sectional area. In most of the world sheet metal thickness is consistently specified in millimeters. Gague ga is a length measurement unit for diameters originating in north america and belongs to the browne sharpe metering system.
