several commonly used cold steel coil

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.

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 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

This product is based on cold -rolled steel strip as substrate,after continuous hot-dip galvanizing process and produced products.It is an excellent resistance to atmospheric corrosion of coated steel,cold-rolled sheet coil after the galvanized can extend the service life for 15-20 years.

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).

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.

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.

Steel Coil Can be used for air conditioning equipment, HVAC ductwork, wood connectors, slot machine parts, computer cabinets, TV cable boxes, building panels, display cases, electronic equipment, garbage cans, guide rails, heating equipment, highway culverts, garage doors, motor housings, washing machines and dryers, home appliances, lighting fixtures, mailboxes, outdoor signs, refrigerators and freezers,roof flashing, decking, tool boxes, vending machines, framing studs, rain gutters and downspouts.

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.
