How Is Sheet Metal Gauge Defined

So inversely the smaller the gauge number the thicker the metal.

How is sheet metal gauge defined.

To help this blog will explain the gauge system and features a sheet metal gauge chart. Sheet metal is available in flat pieces or coiled strips. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. This is a great time saver because it ensures that the solidworks designer will not inadvertently create a model with a bend radius that we cannot manufacture with available tooling.

As the gauge number increases the material thickness decreases. 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. When working with sheet metal the term gauge is often used.

Usually a bigger number means there s more of something but 18 gauge steel is thinner than 16ga not thicker. Metal decking is most commonly 16 18 20 and 22 gauge in thickness. The coils are formed by running a continuous sheet of metal through a roll slitter. Gague ga is a length measurement unit for diameters originating in north america and belongs to the browne sharpe metering system.

A measure of thickness for sheet metal. Then we use hands for horses and gauge written as ga for metal. Sheet metal is specified in gauge so rather than design. How gauge thickness works.

These choices will be defined in our sheet metal gauge table based on available tooling and material wall thickness. Why gauge thickness matters. Gauge is a dimensionless number sometimes spelled gage and confusingly it works backwards. The larger the gauge number the thinner the metal.

In most of the world sheet metal thickness is consistently specified in millimeters. When working with sheet metal it is common for the term gauge to be used someone unfamiliar with the gauge system may not understand what is meant by 18 gauge steel for example.
