Expanded Metals
Expanded metal is used primarily for grating, filtration media, and fencing. Carbon and stainless steels can be perforated with holes or expanded to a diamond shaped pattern, which reduces the surface area.

Tapered Rolling
Another purpose of reducing is to make tapered material. As an example, knives are made from high carbon steel that is heated up red hot and reduced from a thickness of approximately 3/16” to 1/16” by 10” to 48” long.
4-High Rolling Mills
Four-high rolling mills can be put in tandem, two to seven stands, instead of a reversing mill. They can be equipped with load cells to tell the separating force and hydraulic or mechanical screw downs, depending if it is hot or cold rolling. Sometimes mechanical screw downs are preferred when there is a risk of fire.
What Is A Rolling Mill?
In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.
