Good Quality Cold Rolled Steel zinc Coil

The steel coil is a product of rolling and winding a piece of steel strip or steel sheet. The width of a steel coil is larger compared to its thickness. The method of producing steel coil is based on how it should be classified, whether as a cold-rolled, galvanized or hot rolled steel coil.

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.

Galvanised steel is represented by cold- and hot-rolled coils with a zinc coating, which helps to protect the steel against atmospheric corrosion. Galvanised steel coils are successfully used in industries with stringent requirements for corrosion resistance, durability, strength and appearance, and can be formed or have various coatings applied.

Galvanized Steel Sheet in Coil (GI) is produced by passing the Full Hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc’s characteristics.

g20 65mm galvanized gi steel coil strips is mainly used in the construction of household appliances, automobile containers, especially steel structure building, automobile parts, steel plate warehouse manufacturing and other industries. Their characteristics are mainly: strong corrosion resistance, good surface quality, economic and practical.

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 an emerging galvanized and galvalume steel, tinplate sheet, PPGI Cold Rolled Ss340 Steel Material Metal Galvanized Steel Coil,hot and cold rolled sheet, ppgi ppgl company integrating production, supply, sales and export. After years of development and improvement, has become the large international steel companies. It is a large-scale PPGI,Galvanized steel ,Carbon steel industry group integrating smelting, processing, domestic trade, import and export.

Cold rolled steel coil is rolled at room temperature and then rolled again below its recrystallization temperature. This process enables better control over finished product shape, thickness, dimensions, and a more consistent finish.

The material composition of the product is mainly iron carbon alloy, generally containing a small amount of silicon,manganese, sulfur and phosphorus. Different brands correspond to different hardness, thermoplastic, plasticity and weldability. If you don’t understand, you can tell us your requirements.

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.

The hot plate is divided into the pickling plate and the unpickling plate. The surface of the pickling plate becomes the normal metal color because of pickling, but the surface of the unsold-rolled plate is not as high as that of the cold-rolled plate, or the existence of ferrosoferric oxide layer, colloquially it is fire-roasted, and if the storage environment is not good, usually with a little embroidery.

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 steel 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.

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.
