Cold rolling is done when the metal is able to form "new grains" as the old ones are deformed by rolling and bending the metal. Typically, mills take hot rolled steel after it's mostly or completely cooled and work it to its final dimension by either rolling it, extruding it, or drawing the metal over a mandrel.
