Gague ga is a length measurement unit for diameters originating in north america and belongs to the browne sharpe metering system.
12ga sheet metal thickness.
Working with sheet metal as shown in figure 1 gauge sizes can be confusing at the best of times.
Gague are used to specify the thickness of a metal sheet.
Hence 4 gauge material is thicker than 6 gauge material.
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.
A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material.
The gauge number 18 holds no relevance to the actual measurements.
As the gauge number increases the material thickness decreases.
For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
Sheet metal gauges work opposite to what one might consider the norm.

When working with sheet metal the term gauge is often used.
The following sheet metal gauge size reference chart gives the weight and thickness of sheet metal given as a gauge sometimes spelled gage and indicates the standard thickness of sheet metal and wire for most materials as the gauge number increases the material thickness decreases.
Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness.
