Cold Rolled Steel Manufacturing Process
Cold rolled steel is produced by:
- Pickling hot rolled coils
- Cold reduction rolling
- Annealing to restore ductility
- Skin-pass rolling for surface and flatness control
This process results in steel with excellent surface appearance and tight thickness tolerances.
