The manufacturers standard gage provides the thicknesses for standard steel galvanized steel and stainless steel.
For example one company might sell a product as being 24 gauge but in reality the thickness of the metal could vary from 0 018 to 0 0335 based upon exactly how that company looks at things and how big of a tolerance they allow for.
