The primary function of hot rolling mills is to use steel billets to create steel and stainless steel crosssections in various diameters. Steel heated in rolling mills is often used throughout the whole manufacturing process. The rotating rolls continue to move as they shape the steel sections and reduce the thickness of the steel.

Hotrolled steel is mainly produced at rolling mills consisting of stands. For example, hotstrip mills can consist of up to 15 "quarto" stands (, each stand is complete with two pairs of rolls) and edgers to form the strip edges. Hotrolled plate production using slabs includes the following steps: Feeding slabs into reheating furnaces.
