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. This is known as the manufacturers standard. Standard gauges of sheet metal chart. There is no conversion formula due to the difference between ga.

The following sheet metal gauge size reference chart gives the weight and thickness of sheet metal given as a gauge sometimes spelled gage and indicates the standard thickness of sheet metal and wire for most materials as the gauge number increases the material thickness. Related product s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. 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. The comparison of different unit systems is shown in the table below. As the gauge number increases the material thickness decreases. In most of the world sheet metal thickness is consistently specified in millimeters.

The larger the number of gauge is the smaller the diameter is. Please note that astm states in specification astm a480 10a the use of gage number is discouraged as being an archaic term of limited usefulness not having general agreement on. 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.

Gague ga is a length measurement unit for diameters originating in north america and belongs to the browne sharpe metering system. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. It is also used to indicate thickness after promotion. The larger the gauge number the thinner the metal.
