Color-coated coils use hot-dip galvanized sheets, hot-dip galvalume sheets, electro-galvanized sheets, etc. as substrates. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic coatings are coated on the surface, and then A product that is baked and solidified.
Colored steel coils are named after being coated with organic coatings of various colors, referred to as color-coated coils.
Manufacturing process
1. Substrate preparation: The substrate is usually cold-rolled or hot-rolled steel coils or plates, which are cleaned and pretreated to ensure that the surface is free of contaminants.
2. Coating treatment: The surface of the substrate is coated with one or more layers of coatings of specific colors and types, usually including primers, coatings and protective films. These coatings can provide anti-corrosion, anti-oxidation, weather resistance, wear resistance and other properties.
3. Processing and shaping: The coated steel coils are processed into the required coils or plates through rolling, cutting and other processes.
Coating type
1. Polyester coating (PE): Usually used in general building materials and home appliance manufacturing to provide good weather resistance and decorative properties.
2. Silicon modified polyester (SMP): It has good weather resistance and heat resistance, and is suitable for harsh environmental conditions.
3. Fluorocarbon coating (PVDF): It has excellent weather resistance, chemical resistance and wear resistance, and is often used in high-end construction and automobile manufacturing and other fields.
Application areas
1. Building materials: Used to manufacture roof panels, wall panels, doors and windows, etc., to increase the decoration and durability of buildings.
2. Home appliance manufacturing: Used to manufacture casings and components of home appliances such as refrigerators and washing machines to increase the appearance appeal and durability of the product.
3. Automobile manufacturing: Used in automobile shells, body panels and other components to provide vehicle decoration and anti-corrosion properties.
Color-coated steel coils have the advantages of strong decoration, good weather resistance, and convenient construction. They are suitable for a variety of fields that require aesthetics and durability. Choose from different types of coatings and textures to meet the needs of different application scenarios.
