slightly malleable cold rolled coil

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.

Galvanized strip steel is a cold-rolled or hot-rolled, long and narrow strip of steel that is plated with a layer of raw materials called (zinc, aluminum) to varying degrees. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

Galvanized steel coil, immersing the thin steel plate in the molten zinc bath, and adhering a layer of zinc thin steel plate on the surface. It is mainly produced by the continuous galvanizing process, that is, the coiled steel plate is continuously immersed in the zinc-melted plating tank to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also made by the hot-dip method, but it is heated to about 500 °C immediately after exiting the tank to form an alloy film of zinc and iron. This galvanized steel coil has good paint adhesion and weldability.

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.

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.

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–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.
