Standard Sheet Metal Thickness

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

Standard sheet metal thickness.

Sheet metal is any metal that has a thickness in between 0 5 6 millimetres. Millimetres mils gauge. 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 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.

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. Approximate thickness in decimal parts of an inch. Gauges are neither standard nor metric and the values are independent of those measurement systems. Gauges are used to specify the thickness of a sheet metal.

The standard thickness of sheet metal depends on the gauge and the type of metal. There are other measurement units used to categorise metals by thickness though. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. Foils sheets and plates are pretty much the same with the only difference being in thickness.

Thicknesses can vary significantly. A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material. 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. Standard gauge for sheet and plate iron and steel.

As the gauge number increases the material thickness decreases. Approximate thickness in fractions of an inch. Sheet metal is one of the shapes and forms metal can be bought in. Extremely thin sheets are considered foil or leaf and pieces thicker than 6 mm 0 25 in are considered.

For example 3 gauge steel is 0 2391 inches thick while a sheet of 3 gauge zinc is 0 006 inches thick.
