Low Carbon Steel Sheet HRC Mild MS Iron Black A36 SS400 0.30-3.5mm Thickness Hot Rolled Cold Rolled Steel Coil
Our low carbon steel sheets and coils are manufactured using advanced cold-rolling processes, delivering exceptional surface quality and dimensional precision for demanding industrial applications.
Cold-rolled steel production begins with hot-rolled coils as raw material, progressing through multiple precision stages:
- Pickling to remove surface scale
- Cold rolling for dimensional accuracy
- Degreasing to eliminate lubricants
- Annealing for material softening
- Leveling for flatness control
- Shearing to final dimensions
