What is cold rolled steel?

Cold Rolled Steel is produced by the vertical compression of 'Hot Rolled Coil' to a desired thickness.

After the cold rolling process, the metal can be coated with zinc (Zn) by either hot-melt or electrolytic coating to be used as galvanized steel sheets or coils. Cold rolled steel can also be painted for various purposes.

Having a wide range of applications including cars, computer casing, home appliances and construction materials, cold rolled steel is one of the most common types of metal that we see in our daily lives.

HYUNDAI HYSCO's cold rolling mills produce both cold rolled coils and sheets. However, most of the cold rolled steel strips is coiled to an even length before being shipped out.
