This is known as the manufacturers standard.
How thick is 16 gauge aluminum sheet metal.
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.
Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel.
Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge.
A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material.
Gauge sheet steel.

For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick.
Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness.
As the gauge number increases the material thickness decreases.
The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
