Hot rolled steel refers to steel sheets that have been thinned up to 6 mm by heating, pressing, and extending semi-finished steel slabs made by processing molten metal from blast furnaces. Hot rolled products are widely used in different industries including automotive, structures and steel pipes for construction.

A cold rolled steel sheet is produced by pickling a hot coil and rolling it uniformly at an appropriated temperature to a thinner thickness. It has excellent surface configuration and superb mechanical properties for use in automobile and electronic appliance production.

Cold-rolled steel in the pickling process using hydrochloric acid to remove the surface scale products.

Thick plates normally stand for steel plates 6mm or thicker and are made by hot-rolling a semi product slab 200mm or thicker and then through follow-up processes such as cooling or heat treatment.

Zinc-coated sheet is cold-rolled sheet that has been covered on both sides with zinc to improve corrosion resistance.

By compressing the pattern on the surface of the steel sheet, it is used as a flooring material of the stairs and facilities for the slip.
