Prepainted steel coils
|Product name||Prepainted steel coils|
|Material||galvanized steel coils, galvalume steel coils|
|Color||As per the RAL code or based on the sample|
Introduction: Color-coated coils are based on hot-dip galvanized sheets, hot-dip galvalume sheets, electro-galvanized sheets, etc. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or more layers of organic paint are applied to the surface, and then After baking and curing products. It is named after the colored steel coil coated with various organic coatings of different colors, referred to as color coated coil.
Coating type of pre-painted coil
Good adhesion, rich colors, wide range in formability and outdoor durability, moderate chemical resistance, and low cost.
Silicon modified polyester
That is (SMP), the hardness of the coating film, abrasion resistance and heat resistance are good, as well as good external durability and chalking resistance, gloss retention, flexibility, and medium cost.
High durability polyester
Namely (HDP), excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, good paint film adhesion, rich colors, and excellent cost performance.
Namely (PVDF), excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good moldability, dirt resistance, limited color and high cost.
1. The waterproof paper inside cover the steel coils
2. Then the waterproof film cover the steel coils
3. Cover the steel sheet in one roll
4. The protective sheet and steel guard ring protect the steel coils in two sections
5. Four pieces steel strips in vertical and three pieces steel strips in horizontal fasten the entire packages
6. There is the paper tube or steel tube core
Color-coated steel rolls have light weight, beautiful appearance and good corrosion resistance, and can be directly processed. The colors are generally divided into gray, sea blue and brick red. They are mainly used in advertising, construction, home appliances, electrical appliances, furniture, and transportation. industry.
