Cold Rolled Silicon Steel

ASTM Cold Rolled Dipped GI Galvanized Steel Coil GI Strip Coil is hot-rolled steel that has been cleaned of iron oxide scale (pickled) and reduced to a specific thickness through a series of rolling stands (tandem mill) or passed back and forth through a reversing rolling mill. The steel can be heated to controlled temperatures (annealing) depending on mechanical property requirements, and final rolled to the desired thickness.

Ral7016 Dx51d PPGI Gi cold rolled Steel Coil 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 has a wide range of applications, and its advantage is that it has a long anti-corrosion period. It is mainly used for home appliances, office panels, roof sheets, automotive panels, construction and substrate of prepainted steel coils.

Cold coil is made of hot rolled coil at room temperature and below the recrystallization temperature, including plate and coil, of which the sheet delivered is called steel plate, also known as box plate or plate; the long length and delivered in coil is called steel strip, also known as coil plate.

Cold-rolled steel is low-carbon hot-rolled steel that has been rolled at room temperature, below its recrystallization temperature. The steel is then cleaned of oxide scale and finished in a specific series of rolling to just over the desired thickness, heating to controlled temperatures, and final rolling to the desired thickness.

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.

For galvanized steel coils, the steel sheet is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate.

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).

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.
