Standard Sheet Metal Thickness

As the gauge number increases the material thickness decreases.

Standard sheet metal thickness.

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. Millimetres mils gauge. Standard gauge for sheet and plate iron and steel. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

Approximate thickness in decimal parts of an inch. Standard gauge for sheet and plate iron and steel in the united states of america namely. The standard thickness of sheet metal depends on the gauge and the type of metal. 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.

Gauges are used to specify the thickness of a sheet metal. Sheet metal is any metal that has a thickness in between 0 5 6 millimetres. Extremely thin sheets are considered foil or leaf and pieces thicker than 6 mm 0 25 in are considered. Sheet metal is metal formed by an industrial process into thin flat pieces.

Gauges are neither standard nor metric and the values are independent of those measurement systems. Thicknesses can vary significantly. Sheet metal is one of the shapes and forms metal can be bought in. Foils sheets and plates are pretty much the same with the only difference being in thickness.

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. Approximate thickness in fractions of an inch. There are other measurement units used to categorise metals by thickness though.

For example 18 gauge steel according to a gauge conversion chart is 0.
