Short answer: Hot rolling forms metal above its recrystallisation temperature, giving faster, cheaper production of coil, plate and structural sections with a scaled surface and looser tolerances; cold rolling reduces already-hot-rolled stock at room temperature for tight dimensions, a smooth bright finish and higher strength from work hardening. Choose hot rolling for structural and thick sections where cost and formability win, and cold rolling for sheet, strip and components needing precise gauge, flatness and surface.
