Difference Between Hot and Cold Rolled Steel | Metal ...
Hot Rolled Steel. Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel's recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes. ...

Hot Forming Vs. Cold Roll Forming: What's the Difference?
Structural shapes like I-beams are usually hot rolled. The formula of steel used for I beams is different than used in cold forming. It's less ductile and harder, which makes it tougher to bend cold, hence the use for structural shapes that carry a lot of weight! Cold roll forming has many commercial and industrial uses.
