Thickness Expectations in Sheet Products

But "cold rolled strip" is rolled in "strip mills" that are narrow cold mills. The raw material for it is generally "hot rolled sheet" that has been pickled and slit into narrow widths. The end product has thickness variation which is less than sheet mill industry tolerances and is often produced to custom characteristics.

Rolling of Metals: Process and Principles (With Diagram)

In rolling, the metal is plastically deformed by passing it between rollers rotating in opposite direction. The main objective of rolling is to decrease the thickness of the metal. Ordinarily, there is negligible increase in width, so that the decrease in thickness results in an increase in length. ADVERTISEMENTS:
