Sheet metal gauge thickness chart.
Sheet metal gauge size chart gauge or gage sizes are numbers that indicate the thickness of a piece of sheet metal with a higher number referring to a thinner sheet.
As the gauge number increases the material thickness decreases.
The larger the gauge number the thinner the metal.
For a more comprehensive gauge chart you can check out our sheet metal gauge chart here.
It is also used to indicate thickness after promotion.
This chart covers the common and uncommon sheet metal sizes for steel aluminum and galvanized steel.
The larger the number of gauge is the smaller the diameter is.
Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge.

In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge.
This is known as the manufacturers standard.
Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness.
A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
