a wide range of use Cold-rolled steel coil

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.

The DC04 galvanized sheet metal coil Cold Rolled steel coil is packed with PVC film or water-proof kraft in the first layer, the second layer is iron sheet package, then wrapped on the metal pallet or metal square tube with steel strip. It’s is water-proof and sea-worthy, and warmly welcomed by the customers. OEM accepted, besides, the pakage can also be according to your demands.

Cold Rolled zinc Steel Sheet steel coil Galvanized Steel Sheet is defined as a carbon steel sheet coated with zinc on both sides.

It is produced through a process of metal coating which involves passing cold rolled coils through a zinc pot. The process ensures the adherence of zinc to the surface of steel sheet.The zinc layer provides excellent corrosion resistance so that it can prolong the service life of the product.

Using hot-rolled steel coil as raw material, after pickling to remove oxide scale, cold continuous rolling is carried out, and the finished product is rolled hard coil. The cold work hardening caused by continuous cold deformation increases the strength, hardness and toughness and plastic index of rolled hard coil.

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.

cold rolled high quality Galvanized Steel Coil is also used to make wrought iron gates and other items,high tension electrical towers, protective gears, highway signs,make metal pails,build houses,etc.

Cold-rolled steel coil is better in surface quality (such as Surface roughness) than hot plate because it is obtained by cold rolling and some surface finishing is carried out at the same time. Therefore, if the product after the sequence of painting, such as coating quality, there are higher requirements, the general choice of the cold plate.
