Color steel sheet is a product made of strip steel that is continuously subjected to surface degreasing and phosphating and other chemical transfer treatments on the production line, and then coated with organic paint and baked. It not only has the mechanical strength and easy forming performance of steel plate, but also has good decoration and corrosion resistance of organic materials.

Structure of Prepainted Galvanized Steel Coils:
1. Topcoat (finishing) which provides color, pleasing appearance and appearance, and a barrier film to enhance long-term durability.
2. Primer coat to prevent undercutting of paint and enhance corrosion resistance.
3. Pretreatment layer applied for good adhesion and to enhance corrosion resistance.
4. Base steel sheet.
Bright Color Category： Featured for bright and color diversity.
Excellent performance category：
Including PVDF,SMP,energy-saving color steel,self-cleaning color steel,anti-static color steel,antibiosis color steel etc..with excellent functional performance.They are used for large industrial plants and public buildings.
Developed by a special process and special paint. Product of originality category has special surface effects such as wrinkled plates, wooden grain plates, etc, which can meet the customized requirements.
The main material of color paint coating is PE paint, which has the characteristics of low price, various colors, and high-temperature resistance. The corrugated color-coated sheets coating is a product obtained by subjecting a galvanized steel sheet or galvalume steel sheet to a surface chemical treatment (roll coating) or a composite organic coating (such as a PVC coating) and then baking and curing.
Type of paint :
Good adhesion, rich colors, wide range in formability and outdoor durability, medium chemical resistance and low cost.
Silicon modified polyester
That is (SMP), the hardness, wear resistance and heat resistance of the film are good, as well as good external durability and pulverization resistance, gloss retention, general flexibility and medium cost.
High durability polyester
Namely (HDP), excellent color retention and UV resistance, excellent outdoor durability and pulverization resistance, good film adhesion, rich colors and excellent cost performance.
Namely (PVDF), excellent color retention and UV resistance, excellent outdoor durability and pulverization resistance, excellent solvent resistance, good formability, dirt resistance, limited color and high cost.
It has strong durability, corrosion resistance, decoration, and formability. widely used in construction, household appliances, solar energy, transportation and other industries.
