This is known as the manufacturers standard gage for sheet steel.
Carbon steel sheet metal thickness.
As a registered iso 9001 2015 company rolled steel products state of the art equipment meets virtually any requirement in panel flat quality leveling precision slitting close tolerance sheet blanking strip quality edge conditioning precision shearing and complete cold reducing capabilities.
A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
16 ga crs is 2 5 pounds per square foot.
For other materials such as aluminum and brass the thicknesses will be different.
Mesteel steel thickness conversion tables tables.
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 example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
