Imperial Sheet Metal Thickness

Gauges are used to specify the thickness of a sheet metal.

Imperial sheet metal thickness.

For example 18 gauge steel according to a gauge conversion chart is 0. Corresponds to the standard steel thickness of 0 0329 inches 0 84mm. Imperial equivalent in mm. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness.

Thus a 10 gauge steel sheet which has a thickness of 0 1345 inches will weigh 41 82 0 1345 5 625 pounds per square foot. 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. The table below provides conversion to inches. The corresponding galvanized steel thickness is 0 0366 inches 0 93mm and the corresponding aluminum thickness is 0 028 inches 0 71mm.

Metal sheet thickness is measured in gauge. Standard metric sheet in mm. The chart below shows the imperial standard sheet gauge definition with its metric equivalent and today s commercially available ferrous mild steel zintec galvanised steel stainless steel alloys and non ferrous aluminium alloys brass copper sheet. Gauge to thickness chart gauge stainless galvanized sheet steel aluminum fraction inches mm inches mm inches mm inches mm 30 0 0125 0 33 0 0157 0 40 0 0120 0 30 0 0100 0 25.

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. This is known as the manufacturers standard gage for sheet steel.

Gauges are neither standard nor metric and the values are independent of those measurement systems. As the gauge number increases the material thickness decreases. Wire conductor sizes are also measured in gauge and are equivalent to the non ferrous thicknesses listed below but we have an article specific to wire gauge. The story of gauge.
