2. Hot Rolling: The steel is rolled at high temperatures to achieve the desired slab thickness.
3. Cold Rolling: The hot-rolled coils are further rolled at room temperature to refine the thickness, surface finish, and mechanical properties.
4. Annealing: The material is heat-treated to relieve internal stresses and restore ductility.
5. Surface Treatment: Depending on the application, the strips may undergo polishing, bright annealing, or pickling.
6. Slitting and Finishing: The final coils are slit into narrow strips according to customer specifications and quality-checked for thickness, flatness, and edge precision.

The result is a high-performance steel strip with exceptional surface uniformity, mechanical consistency, and corrosion resistance.
