Common Sheet Metal Thickneeses

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

Common sheet metal thickneeses.

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. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. 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.

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

16 ga crs is 2 5 pounds per square foot. The larger the gauge number the thinner the metal. This is known as the manufacturers standard gage for sheet steel. Gauge to thickness chart click here for a printable pdf chart gauge.

Millimetres mils gauge foils sheets and plates are pretty much the same with the only difference being in 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. Sheet metal is any metal that has a thickness in between 0 5 6 millimetres. 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.

For other materials such as aluminum and brass the thicknesses will be different. There are other measurement units used to categorise metals by thickness though. The two most common metals used for ductwork are aluminum and galvanized steel and the requirements for both are listed in the international mechanical code book. The gauge number 18 holds no relevance to the actual measurements.

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. A aluminium sheets metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material. But this subchapter shall not be construed to increase duties upon any articles which may be imported. Sheet metal is one of the shapes and forms metal can be bought in.

For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
