What is the average thickness of a sheet of steel?
Sheet metal thickness gauges for steel are based on a weight of 41.82 pounds per square foot per inch of thickness. This is known as the Manufacturers’ Standard Gage for Sheet Steel. For other materials, such as aluminum and brass, the thicknesses will be different.
Which is thicker 18 gauge steel or aluminum?
For example, in one gauge system, 18 gauge steel measures 0.0478 inches thick, but 18 gauge aluminum is 0.0403 inches thick. Because of the varying thicknesses, a gauge chart should be used to ensure the metal meets the required dimensions. History of the gauge system The gauge system has long history in metal fabrication.
