Cold rolled steel coil JISG3141-2005

Galvanized refers to a surface treatment technology that coats a layer of zinc on the surface of metals, alloys or other materials for aesthetics and rust prevention. The main methods used are hot-dip galvanizing and electro-galvanizing. It prevents corrosion of steel, and its protective performance is closely related to the thickness of the coating.

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.

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.

We are the professional galvanized steel products supplier in China. The company focus on galvanized production for 7 years, we have our own production line, supply galvanized coil, galvanized sheet, galvanized pipe and coating products. Our company has 200 people and a monthly output of 6,000 tons.

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.

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 refers to a surface treatment technology that coats a layer of zinc on the surface of metals, alloys or other materials for aesthetics and rust prevention. The main methods used are hot-dip galvanizing and electro-galvanizing. It prevents corrosion of steel, and its protective performance is closely related to the thickness of the coating.

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.

Good Quality Cold Rolled Steel zinc Coil 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.
