Standard Sheet Metal Thickness

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

Standard sheet metal thickness.

Gauges are used to specify the thickness of a sheet metal. There are other measurement units used to categorise metals by thickness though. Extremely thin sheets are considered foil or leaf and pieces thicker than 6 mm 0 25 in are considered. A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material.

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 is any metal that has a thickness in between 0 5 6 millimetres. As the gauge number increases the material thickness decreases. Thicknesses can vary significantly.

Approximate thickness in decimal parts of an inch. Sheet metal is one of the shapes and forms metal can be bought in. Standard gauge for sheet and plate iron and steel. For example 18 gauge steel according to a gauge conversion chart is 0.

Gauges are neither standard nor metric and the values are independent of those measurement systems. Standard gauge for sheet and plate iron and steel in the united states of america namely. Millimetres mils gauge. Approximate thickness in fractions of an inch.

Sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes countless everyday objects are fabricated from sheet metal. For example 3 gauge steel is 0 2391 inches thick while a sheet of 3 gauge zinc is 0 006 inches thick. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. Sheet metal is metal formed by an industrial process into thin flat pieces.

The standard thickness of sheet metal depends on the gauge and the type of metal.
