mechanical properties cold-rolled steel coils

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, 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.

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.

Galvanized steel coil, also known as galvanized coil, is a galvanized coil product. Galvanized coil, a steel material coated with zinc. The galvanized coil is the predecessor of the galvanized sheet. The galvanized coil is cut into sheets by equipment. The galvanized coil is placed on the shelf with a forklift or aerial crane, and then transferred, flattened and cut by the equipment.

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. , so the stamping performance will deteriorate and can only be used for parts with simple deformation.

Gnee is a leading supplier of galvanized steel sheet & coil. Galvanized steel is defined as a carbon steel sheet coated with zinc on both sides.

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.

Metal Cold Rolled Galvanized Steel Coil is essentially hot rolled steel that is further processed in cold reduction materials. Here, the material is cooled followed by annealing and/or tempers rolling. Steels of different grades and specifications can be either hot or cold rolled.
