The difference between hot-rolling mills and cold-rolling mills comes down to the required temperature when forming the steel. Cold-rolled steel products usually have higher precision, strength, and surface finishes. Hot-rolling is less expensive, provides better workability, and adds little to no internal stress as the steel cools gradually.
