cold rolled galvanized steel thickness 3.0 mm Coil weight 6-9MTS

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.

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.

Cold-rolled steel coils have good properties, and cold-rolled strips and steel sheets with thinner thickness and higher precision can be obtained by cold-rolling. High flatness, high surface finish, clean and bright surface of cold-rolled sheet. It is easy to be coated and processed and has the characteristics of high stamping performance and low yield point, so cold-rolled steel coil has a wide range of uses, mainly used in automobiles and building materials. At the same time, it is also the substrate for the production of galvanized steel sheets in coil and galvalume steel coil.

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. It must be annealed to restore its mechanical properties, and those without annealing are called hard rolled coils.

It must be annealed to restore its mechanical properties, and those without annealing are called hard rolled coils. Hard-rolled coils are generally used to make products that do not require bending or stretching, and those with a thickness of less than 1.0 are rolled on both sides or four sides with good luck.

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.

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).

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.
