Common Sheet Metal Thickneeses

The larger the gauge number the thinner the metal.

Common sheet metal thickneeses.

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. Approximate thickness in fractions of an inch. Approximate thickness in decimal parts of an inch. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge.

There are other measurement units used to categorise metals by thickness though. For other materials such as aluminum and brass the thicknesses will be different. As the gauge number increases the material thickness decreases. Haomei common used aluminum sheet thickness 0 3mm 0 5mm 0 8mm 1mm 1 2mm 1 5mm 2mm 2 5mm 3mm 4mm 5mm and above.

Gauge differs between ferrous iron based metals and nonferrous metals such as aluminum or copper. The standard thickness increases for larger dimensions of piping made from sheet metal so it can withstand the stresses of greater length and diameter without buckling under its own weight. For 18 ga crs the weight is 2 0 pounds per square foot and for 20 ga crs the weight is 1 5 pounds per square foot. The gauge number 18 holds no relevance to the actual measurements.

16 ga crs is 2 5 pounds per square foot. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. Sheet metal is one of the shapes and forms metal can be bought in. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.

But this subchapter shall not be construed to increase duties upon any articles which may be imported. Millimetres mils gauge foils sheets and plates are pretty much the same with the only difference being in thickness. Sheet metal is any metal that has a thickness in between 0 5 6 millimetres.

A aluminium sheets metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. The same and no other shall be used in determining duties and taxes levied by the united states of america on sheet and plate iron and steel. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge.

This is known as the manufacturers standard gage for sheet steel.
