G550 Az150 Aluzinc Steel Coil 0.40mm Thickness1200mm Width Galvalume Steel Coil
The surface coating of aluminized zinc coil is composed of 55% aluminum, 43.5% zinc and a small amount of other elements. The surface of the aluminized zinc coating is a honeycomb structure under the microscopic view. In this case, although the aluminum-zinc coating also plays the role of anode protection, on the one hand, due to the reduction of zinc content, on the other hand, the zinc material is wrapped in aluminum and is not easy to electrolyze, so the role of anode protection is greatly reduced. Therefore, once the galvalume steel coil is cut, and it will rust soon when the cut edge is basically lost and protected. Therefore, the galvalume steel coil should be cut as little as possible. Once cut, the edge can be protected by applying anti-rust paint or zinc-rich paint. The service life of the galvalume steel coil is prolonged.
Galvanized coil thickness: 1.2-2.0 (mm) Width: 1250 (mm) Product name: galvanized coil
Performance: mainly used low carbon steel, requires good cold bending and welding performance, as well as certain stamping performance. Cold rolled strip is widely used, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, canned food and so on.
Cold rolled thin steel plate is short for common carbon structural steel cold rolled plate, also known as cold rolled plate, commonly known as cold plate, sometimes mistakenly written in cold tie plate. Cold plate is made of ordinary carbon structural steel hot rolled steel strip, after further cold rolled into less than 4mm thickness of steel plate. Due to rolling at room temperature, no oxide sheet, therefore, the surface quality of cold plate is good, high dimensional accuracy, coupled with annealing treatment, its mechanical properties and technological properties are better than hot rolled thin steel plate, in many fields, especially in the field of household appliances manufacturing, has gradually replaced the hot rolled thin steel plate with it.
