Product Description
Steel coil, also known as coil steel. The steel is rolled by hot and cold pressing. It has high strength and toughness, and is easy to process and weld, so it is widely used in construction, manufacturing, chemical industry and other fields. Carbon steel coils can be used as structural materials for the construction of bridges, tunnels, high-rise buildings and other buildings, and can also be used to manufacture a variety of automobiles, electrical appliances, machinery and other products, in addition, carbon steel coils can also be applied to aviation, energy, chemical and other fields, used to manufacture aircraft parts, engine parts and oil pipelines. In general, the higher the carbon content of carbon steel, the greater its hardness and strength.
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.
