Selecting A Cold Rolled Steel Sheet With The Right Surface
The surface finish for steel can affect how resistant the steel is to corrosion. For example, a coarse polished finish will have grooves that allow for the gradual accumulation of chloride ions. This can lead to corrosion. The importance of surface finish is determined by a variety of factors, including whether the steel will be used in a corrosive environment, like a coastal location. Usually, the process of creating cold rolled sheet metal will produce steel that has a better surface than hot rolled steel, but there are several methods that can be used to further improve the surface.
