Cold Rolled Steel Sheet Standard Thickness

Mill limits cold rolled steels are available in thicknesses from 0 015 0 135 in.

Cold rolled steel sheet standard thickness.

The gauge number 18 holds no relevance to the actual measurements. The metal is rolled to the thickness of 0 5 3 mm in case of mild steel and 0 5 5 mm in case of stainless steel. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. Mm 0 4 0 5 0 6 0 7 0 8 0 9 1 0 1 2 1 4 standard thickness 1 6 1 8 2 0 2 3 2 5 2 6 2 8 2 9 3 2.

The half products are then fed to cold reduction mills. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.

We work with nominal thicknesses so it s important to know the thickness tolerance on the material you chose in order to know if the final product will be suitable for your application. The material is cooled by the use of oil which also acts as a lubricant during the rolling process. The standard coil inner diameter is 24 in. As the metal sheet gets thinner between the rolls its speed increases.
