SC2 cold rolled steel

Cold-rolled strips are widely used, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, canned food, etc. Cold-rolled sheet is the abbreviation of ordinary carbon structural steel cold-rolled sheet, also known as cold-rolled sheet, commonly known as cold-rolled sheet, and sometimes mistakenly written as cold-rolled sheet.

Cold-rolled sheet coil has good properties, that is, cold-rolled strip and steel sheet with thinner thickness and higher precision can be obtained by cold-rolling, with high flatness, high surface finish, clean and bright surface of cold-rolled sheet, and easy to be coated. It has a wide range of processing and varieties, and has a wide range of uses.

Galvanized Steel Coil (GI) is produced by passing the Full Hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc’s characteristics. Usually, hot-dipped galvanized steel sheet and galvanized steel coil process and specifications are basically the same.

Cold-rolled coil refers to a steel strip that is directly rolled into a certain thickness with a roll at room temperature and rolled into a whole coil with a coiler. Compared with hot-rolled coils, cold-rolled coils have a brighter surface and higher finish, but will generate more internal stress and are often annealed after cold-rolling.

Compared with hot rolled steel plate, Galvanized steel Ss400 cold rolled steel coil thickness is more accurate, and the surface is smooth, beautiful, but also has a variety of superior mechanical properties, especially machining performance.

Coils are divided into chilled coils and cold rolled coils. The difference between the two is that in appearance, the general chilled coil is slightly black; the surface quality, structure, and dimensional accuracy of the cold-rolled sheet are better than that of the chilled coil; in terms of performance, because the hot-rolled coil goes through the cold rolling process The directly obtained chilled coils undergo work hardening during cold rolling, resulting in an increase in yield strength and some residual internal stress, and the external performance is relatively “hard”, so it is called chilled coils.

g20 cold rolled high quality Galvanized Steel Coil composition by weight ratio of 55% aluminum,43.4% zinc,1.6% silicon, at high temperature 600 high temperature solidification and aluminized zinc plate surface is a unique smooth flat gorgeous star flower, the base color is silver white special coating structure makes it has excellent corrosion resistance

Galvanized coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery, commerce and other industries. The construction industry is mainly used to manufacture anti-corrosion roof panels and roof grilles of industrial and civil buildings

Cold rolled steel coil is a type of steel coil product developed from hot rolled steel coil and sheet, surface quality and dimension precision are quite low after hot rolling process, it can’t be used where surface quality and dimensions are required. Until now, cold rolled coils have been available and successfully used for a variety of applications.
