16 ga crs is 2 5 pounds per square foot.

Common sheet metal gauges.

The corresponding galvanized steel thickness is 0 0366 inches 0 93mm and the corresponding aluminum thickness is 0 028 inches 0 71mm. 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. 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. In the uk the birmingham gage bg is used for a variety of metals and should not be confused with the birmingham wire gage bwg which is used for wires.

The thickness of sheet metal starts from 0 5 mm and goes up to 6 mm. Metal gauges below you ll find the info you need with our sheet steel stainless steel and aluminum sheet metal charts. Anything above that is a metal plate. Approximate thickness in decimal parts of an inch.

For other materials such as aluminum and brass the thicknesses will be different. The thickness of foil is usually up to 0 2 mm. Metal foil is especially common with aluminium often referred to as tinfoil. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.

Approximate thickness in fractions of an inch. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. For 18 ga crs the weight is 2 0 pounds per square foot. Sheet metal is the next in line.

Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel. Corresponds to the standard steel thickness of 0 0329 inches 0 84mm. Lastly a standard exists for zinc in which a higher gauge number indicates a thicker sheet. 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.
