Cold Rolled Galvanized Aluminum Galvanized DC01 G550 G90 SGCC Galvanized Steel Coil

Coils are divided into chilled coils and cold rolled coils. The difference between the two is that in appearance, the general chilled coil is slightly black; the surface quality, structure, and dimensional accuracy of the cold-rolled sheet are better than that of the chilled coil; in terms of performance, because the hot-rolled coil goes through the cold rolling process The directly obtained chilled coils undergo work hardening during cold rolling, resulting in an increase in yield strength and some residual internal stress, and the external performance is relatively “hard”, so it is called chilled coils.

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.

Galvanized steel coil, also known as galvanized coil, is a galvanized coil product. Galvanized coil, a steel material coated with zinc. The galvanized coil is the predecessor of the galvanized sheet. The galvanized coil is cut into sheets by equipment. The galvanized coil is placed on the shelf with a forklift or aerial crane, and then transferred, flattened and cut by the equipment.

Cold-rolled coil refers to a steel strip that is directly rolled into a certain thickness with a roll at room temperature and rolled into a whole coil with a coiler. Compared with hot-rolled coils, cold-rolled coils have a brighter surface and higher finish, but will generate more internal stress and are often annealed after cold-rolling.

SS400 zinc Cold Rolled Steel Coil refers to a steel strip that is directly rolled into a certain thickness with a roll at room temperature and rolled into a whole coil with a coiler. Compared with hot-rolled coils, cold-rolled coils have a brighter surface and higher finish, but will generate more internal stress and are often annealed after cold-rolling.

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.

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.

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.

Factory Direct Sale Cold Rolled Zinc Coated Galvanized Steel Coils 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.

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.

Galvanized steel coil is a kind of steel coil that immersed in the dissolved zinc bath to adhere to the surface with a layer of zinc. At present, the main method is to make galvanized steel coil be dipped in a bath with dissolved zinc.

Galvanized steel cold rolled coil has a wide range of uses, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, food cans, etc., industrial panels, roofing and siding for painting, etc.
