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.

Galvanized steel coil refers to rolled coil steel product that has been cleansed and heated before it is dipped into molten zinc. The hot-rolled or cold-rolled steel strip, sheet, or slab can be coated with zinc and iron (GA) or zinc (GI).

Top quality JIS 0.45mm*1200mm galvanized steel coil can produce zero spangles, small spangles, ordinary spangles, etc. The thickness is from 0.125mm to 4.5mm, the width is from 500mm to 1250mm, the zinc coating is from 40-275 g/m², the surface is passivated and oil can be coated.

ASTM standard size cold rolled galvanised steel coil –Dip a sheet of zinc into a molten zinc bath so that galvanized steel coil’s surface adheres to a sheet of zinc.At present, galvanized steel coil’s main use of continuous galvanized process production, that is, the coil of steel plate continuously immersed in the melting zinc plating tank made of galvanized steel plate;Alloyed galvanized steel sheet.

Cold-rolled is processed from hot-rolled sheets at room temperature. Although the temperature of the steel sheet will be heated during the processing, it is still called cold-rolled. Due to the continuous cold deformation of hot rolling, the mechanical properties are relatively poor and the hardness is too high. It must be annealed to restore its mechanical properties, and those without annealing are called hard rolled coils. Hard-rolled coils are generally used to make products that do not require bending or stretching, and those with a thickness of less than 1.0 are rolled on both sides or four sides with good luck.

Cold Rolled Galvanized Steel Strip Coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry and fishery and commerce industries. Among them, the construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof grilles, etc.

The material composition of the product is mainly iron carbon alloy, generally containing a small amount of silicon,manganese, sulfur and phosphorus. Different brands correspond to different hardness, thermoplastic, plasticity and weldability. If you don’t understand, you can tell us your requirements.

High quality cold rolled steel coil full hard Galvanized steel coil is processed from hot-rolled sheets at room temperature. Although the temperature of the steel sheet will be heated during the processing, it is still called cold-rolled. Due to the continuous cold deformation of hot rolling, the mechanical properties are relatively poor and the hardness is too high.

Cold-rolled steel coils have good properties, and cold-rolled strips and steel sheets with thinner thickness and higher precision can be obtained by cold-rolling. High flatness, high surface finish, clean and bright surface of cold-rolled sheet. It is easy to be coated and processed and has the characteristics of high stamping performance and low yield point, so cold-rolled steel coil has a wide range of uses, mainly used in automobiles and building materials. At the same time, it is also the substrate for the production of galvanized steel sheets in coil and galvalume steel coil.
