Imperial sheet metal thickness.

Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. Metal sheet thickness is measured in gauge. Gauges are used to specify the thickness of a sheet metal. Imperial equivalent in mm.

The corresponding galvanized steel thickness is 0 0366 inches 0 93mm and the corresponding aluminum thickness is 0 028 inches 0 71mm. This is known as the manufacturers standard gage for sheet steel. 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. Gauges are neither standard nor metric and the values are independent of those measurement systems.

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. 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. The table below provides conversion to inches. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

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. Unit 4 yakira buildings 83 sefton lane maghull liverpool l31 8bu. As the gauge number increases the material thickness decreases.

For other materials such as aluminum and brass the thicknesses will be different. 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. 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.
