Common Sheet Metal Gauges

Metal gauges below you ll find the info you need with our sheet steel stainless steel and aluminum sheet metal charts.

Common sheet metal gauges.

For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. Sheet metal manufacturing and services the following sheet metal gauge size reference chart gives the weight and thickness of sheet metal given as a gauge sometimes spelled gage and indicates the standard thickness of sheet metal and wire for most materials as the gauge number increases the material thickness decreases. Approximate thickness in decimal parts of an inch. The thickness of sheet metal starts from 0 5 mm and goes up to 6 mm.

Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel. Sheet metal is the next in line. 16 ga crs is 2 5 pounds per square foot. Lastly a standard exists for zinc in which a higher gauge number indicates a thicker sheet.

This is known as the manufacturers standard gage for sheet steel. Metal foil is especially common with aluminium often referred to as tinfoil. The story of gauge. The thickness of foil is usually up to 0 2 mm.

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. The corresponding galvanized steel thickness is 0 0366 inches 0 93mm and the corresponding aluminum thickness is 0 028 inches 0 71mm. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. The brown and sharpe gage also known as the american wire gage awg is used for most non ferrous metals such as aluminum and brass.

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. Anything above that is a metal plate. For 18 ga crs the weight is 2 0 pounds per square foot. Approximate thickness in fractions of an inch.

For the purpose of securing uniformity the following is established as the only standard gauge for sheet and plate iron and steel in the united states of america namely.
