Cold Rolled steel
Cold rolled steel is made by removing the oxide layer of hot rolled steel through acid pickling and rolling it at room temperature. Compared with hot rolled steel, its thickness is more even, and its surface is smoother. It is glossy and sufficiently withstands pressure. It can be processed even though it is long. Its universality is good. It is used to manufacture automobile bodies, electronic equipment, home appliances, architecture, and office supplies.
General cold rolled steel
This steel is generally used for refrigerator doors, drums, and furniture. For automobiles, cold rolled steel is used for its roof, fender, hood, quarter, oil pan, and spring house.
Steel for general structure
This steel is not processed, but it is used for steel structures.
Steel for enamel
Its uses are classified into deep processing, processing, and general use according to the manufacturing method and its final use. For deep processing and processing, this steel is used for bathtubs, dehydrators, and general home appliance parts. For general use, it is not processed much, but it is used for kitchen containers.
Its uses are classified into deep processing, processing, general use, and TRIP-type high-strength steel according to the manufacturing method and its final use. This steel is generally used for automobile seats, rail levers, and parking brakes. For processing, it is used for the floor center and bracket. For deep processing, it is used for the main outer body such as the fender and the hood. The TRIP-type high-strength steel is used for the stiffener such as the door and the bumper.
