Heating
In the case of hot-rolled coils, the steel is heated above its recrystallization temperature, making it easier to shape. Cold-rolled coils, on the other hand, undergo a cooling process to achieve the desired properties.
Rolling
The heated or cooled steel is passed through rollers to reduce its thickness and shape it into a coil.
Annealing
In some cases, the coils undergo an annealing process to improve their ductility and eliminate internal stresses.
Surface Treatment
Depending on the application, the steel coils may undergo additional processes like galvanization or coating to enhance their corrosion resistance and appearance.
Cutting and Packaging
The coils are cut into specific lengths and packaged for transportation and storage.
