Professional explanation of color coated steel coil

Color-coated steel coil, collectively referred to as color-coated steel coil in the industry, adopts advanced composite technology to highly integrate steel with bright and rich peritoneal membrane, which has the good performance of various materials, greatly improves the chemical stability of materials, and has more effective anti-rust and anti-corrosion properties. Color steel not only has the excellent quality of steel in terms of flexibility, plasticity, pressure resistance, wear resistance, heat dissipation and high temperature resistance, but also outstanding in terms of color, finish, and hand feel. It is worth mentioning that all the raw materials used in the production of color steel are non-polluting, pollution-free and environmentally friendly materials, and the production process is completely dust-free. Both production and later use have extremely high environmental protection characteristics.

Color steel materials are divided into five categories: packaging, home appliances, building materials, optical materials and decorative materials. Among them, the color steel materials for home appliances are the best and the most refined, and the production requirements are high.

Classification of color steel coil substrates: 1. Cold-rolled substrates have the processing properties of cold-rolled sheets; however, any small scratches on the surface coating will expose the cold-rolled substrates to the air, which will quickly cause red rust on the exposed iron. 2. Galvanized substrate, now the main method of surface galvanizing of steel plate is hot-dip galvanizing. Hot-dip galvanizing is developed from the older hot-dip galvanizing method. It is characterized by smooth appearance, no zinc bumps and burrs, and the thickness is controllable. It can ensure that the mechanical properties of the material remain unchanged, the corrosion resistance is good, and the neutral salt spray test can reach 240 hours.

Color steel coils for construction generally use hot-dip galvanized steel sheets and hot-dip galvanized steel sheets as substrates, and are mainly processed into corrugated sheets or composite sandwich panels with polyurethane, which are used to build steel structure workshops, airports, warehouses, freezers and other industrial and Roofs, walls, doors of commercial buildings.

Home appliance color plates are generally based on electro-galvanized and cold plates, and are used in the production of refrigerators and large air-conditioning systems, freezers, bread machines, and furniture.

In the transportation industry, electro-galvanized and cold plates are generally used as substrates, which are mainly used for oil pans, automotive interior parts, etc.
