There are two types of rolling. With hot rolling, heated metal goes through a rolling machine where it is worked into a sheet or bar. With cold rolling, sheet steel is made thinner at normal temperatures, and its surface is made smooth and uniform. Tsubaki products are used in both hot and cold rolling.
