  • Hot Rolled Steel

    Hot rolled steel products are divided into two groups: hot rolled coils produced through hot rolling and hot rolled steel plates, which are made by cutting material from hot rolled coils. Slabs produced from a continuous casting system are rolled, cooled and coiled into the sizes required by the customers.
    • Steel for Cold Rolled Steel
    • Mild Steel
    • High Strength Steel
    • Advanced High Strength Steel
    • Post Heat Treatment Steel
    • High Carbon Steel
    • Steel for Structure
    • Weather Resistance Steel
    • Steel for Pipe and Tube
    • Steel for Oil Well Pipe
    • Steel for Linepipe
    • Steel for Gas Cylinder


  • Steel Plate

    Steel plates are hot rolled products that have a relatively high thickness. Products having a thickness of over 4.5 mm are classified as steel plates, and those having a thickness of over 100 mm are called thick steel plates. Slabs of steel plates made through continuous casting are tailored to the dimensions specified by the customer through rolling and cooling before being cut into their final sizes.

    • Low Carbon Steel

  • Cold Rolled Steel

    Cold rolled steel is made using hot rolled steel through pickling, cold rolling and heat treatment. It is relatively thin with a thickness of 0.2 mm to 2.0 mm. Cold rolled steel is highly aesthetic and easily machinable, thus widely used for premium applications in modern society. We are increasingly focused on offering value-added products as demand for highly functional, cold rolled products is rising.
