Zinc-Coated Steel Dx51 Grade a Coil 1.0mm Thickness Galvanized Coil

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

The cold plate is a hot-rolled steel strip of ordinary carbon structural steel, which is further cold-rolled into a steel plate with a thickness of less than 4mm. Due to rolling at room temperature, no scale is produced, therefore, the cold plate has good surface quality and high dimensional accuracy, coupled with annealing treatment, its mechanical properties and process properties are better than hot-rolled steel sheets, in many fields, especially In the field of home appliance manufacturing, it has gradually replaced hot-rolled sheet steel

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.

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.

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 is produced through applying Zn coat on both faces by hot dip process. It enjoys both the physical protective feature and the electrochemical protective property of Zn.

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. The hot plate is divided into the pickling plate and the unpickling plate.

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.

High quality cold rolled steel coil full hard Galvanized steel coil is processed from hot-rolled sheets at room temperature. Although the temperature of the steel sheet will be heated during the processing, it is still called cold-rolled. Due to the continuous cold deformation of hot rolling, the mechanical properties are relatively poor and the hardness is too high.

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 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.

Cold-rolled steel coils are made of hot-rolled coils and rolled at room temperature below the recrystallization temperature. Cold-rolled steel has good performance. That is, cold-rolled steel can be thinner and more precise.

Top quality JIS 0.45mm*1200mm galvanized steel coil can produce zero spangles, small spangles, ordinary spangles, etc. The thickness is from 0.125mm to 4.5mm, the width is from 500mm to 1250mm, the zinc coating is from 40-275 g/m², the surface is passivated and oil can be coated.

Cold-rolled is processed from hot-rolled sheets at room temperature. Although the temperature of the steel sheet will be heated during the processing, it is still called cold-rolled. Due to the continuous cold deformation of hot rolling, the mechanical properties are relatively poor and the hardness is too high.
