During hot rolling the microstructure and mechanical properties of the material change with its thermomechanical state, determined by composition, percent reduction, strip thickness, strip speed, and heat transfer. For steels, hot rolling is generally conducted at 850–1200 °C, in the austenite phase, while for aluminum it is conducted at 350–500 °C.

A Steckel mill, also known as a reversible finishing mill, [citation needed] is similar to a reversing rolling mill except two coilers are used to feed the material through the mill. One coiler is on the entrance side and the other on the exit side. The coilers pull the material through the mill, therefore the process is more similar to drawing than rolling.
