Cold-rolled steel coils

Cold-rolled coils are a steel product produced by applying plastic deformation to hot-rolled steel on cold-rolling mills. With such processing, the product can have more accurate dimensional tolerances, better surface quality and improved mechanical properties as compared with hot-rolled coils. Cold rolling is also used to make thinner coils than hot-rolling mills can currently produce (less than 0.8-1.0 mm).

Galvanized steel coil is a kind of steel coil that immersed in the dissolved zinc bath to adhere to the surface with a layer of zinc. At present, the main method is to make galvanized steel coil be dipped in a bath with dissolved zinc.

Cold rolled coil could supply better control of thickness, shape, width, surface finish, and other special quality features that compliment the emerging need for highly engineered end uses. Take construction projets for example: steel sheds, industrial buildings, and garages.

SS400 zinc Cold Rolled Steel 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.

The hot plate is divided into the pickling plate and the unpickling plate. The surface of the pickling plate becomes the normal metal color because of pickling, but the surface of the unsold-rolled plate is not as high as that of the cold-rolled plate, or the existence of ferrosoferric oxide layer, colloquially it is fire-roasted, and if the storage environment is not good, usually with a little embroidery.

g20 65mm galvanized gi steel coil strips is mainly used in the construction of household appliances, automobile containers, especially steel structure building, automobile parts, steel plate warehouse manufacturing and other industries. Their characteristics are mainly: strong corrosion resistance, good surface quality, economic and practical.

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.

AISI coil rolled galvanized steel coil is also known as low or high carbon steel plate and stainless steel coil, characterized by complete specifications,diverse materials; High dimensional accuracy, up to ± 0.1mm;Excellent surface quality, good brightness; Strong corrosion resistance, high tensile strength and fatigue strength;

Cold-rolled sheet in coil form is produced by removing rust from hot-rolled sheet by “pickling” it in a weak acid solution, then washing, brushing, drying, oiling and unrolling the sheet and finally performing cold-rolling by passing the sheet through a reducing mill under pressure and winding it into a roll.

Galvanized 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.

The mechanical engineering workshops of our factory are all equipped with numerical central control ,Our factory has been constantly improving the platform construction, improving the quality of technical team, strengthening the invention of products category, formed complete R & D system and production quality management system, wined high reputation in the iron and steel industry.
