_{Cold Rolled Carbon Steel} 

Remove contaminants from surface of cold rolled steel at electrolytic cleaning line and give heating to maintain 600~800℃ for specific time and get process-ability and improve surface grind and shape by skin pass rolling to make use of it for automobiles, home appliance, furniture, office supplies and architecture.

High Tensile Steel

The steel with tensile strength of 50 kgf/mm2 stronger than common type of steel has been made of carbon steel with 0.2% carbon, silicon, manganese, nickel, chrome and copper to have better performance. Thinner high tensile steel plate can satisfy safety standards more than common steel plate can do, so that it can meet requirements of light weight of automobile business
