Hot-rolled steel products include steel strips (coils) and steel sheets cut from them. The steel strip (roll) can be divided into straight hair rolls and finishing rolls (divided rolls, flat rolls and slit rolls).

Hot continuous rolling can be divided into ordinary carbon structural steel, low-alloy steel, and alloy steel according to its material and performance. According to their different uses, they can be divided into: cold forming steel, structural steel, automotive structural steel, corrosion-resistant structural steel, mechanical structural steel, welded gas cylinder and pressure vessel steel, pipeline steel, etc.
 

Hot-rolled steet/coil from finishing the last hot steel strip mill out through laminar flow cooling to the set temperature, which consists of the winder coil, steel coil after cooling, according to the different needs of users, with different finishing line (flat, straightening, transverse or longitudinal cutting, inspection, weighing, packaging and logo, etc.) and become a steel plate, flat roll and longitudinal cutting steel strip products. Because hot rolled steel products have high strength, good toughness, easy processing and good weldability and other excellent properties, it is widely used in shipbuilding, automobile, bridge, construction, machinery, pressure vessel and other manufacturing industries.

Carbon Structural Steel, it is a kind of carbon steel. The carbon content is about 0.05% ~ 0.70%, some may be as high as 0.90%. It can be divided into ordinary carbon structural steel and high quality carbon structural steel. Mainly used for railway, bridge, all kinds of construction engineering, the manufacture of various metal components bearing static load and mechanical parts and general welding parts which are not important and do not need heat treatment.
