Color-coated coil has light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed. The color is generally divided into gray white, sea blue, brick red, mainly used in advertising industry, construction industry, home appliance industry, electrical industry, furniture industry and transportation. The coating used for color-coated coils selects appropriate resins according to the application environment, such as polyester silicon modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride, etc. The user can choose according to the use.

When it comes to the classification of pressure-type color-coated rolls, many friends only know the tile type classification or thickness classification or color classification, but if it is more professional to talk about the paint film coating classification of pressure-type color-coated rolls, I estimate that a large number of friends will I scratched my head, because the term paint film coating is relatively unfamiliar to everyone, but the paint film coating is one of the key factors related to the quality of the embossed color-coated roll, and it is also one of the key factors in determining the project selection.

At present, many manufacturers selling pressure-type color-coated coils in the market take advantage of the fact that many customers are not very clear about the classification of pressure-type color-coated coils. Shaped color-coated rolls, he provides ordinary stamped color-coated rolls, and the service life of such stamped color-coated rolls will not be very long. When customers react to problems with stamped color-coated rolls, it may have been a year or two. , it is not easy to find after-sales service, only to be dumb, so the editor said here that the classification of the paint film coating of the pressure-type color-coated roll is very important.

The paint film coating of the embossed color coating roll is divided into four kinds: ① polyester coating (PE) color coating; ② high durability coating (HDP) color coating; ③ silicon modified coating (SMP) color coating board; ④ fluorocarbon coating (PVDF) color-coated board;

1. Ester coating (PE) color coated board
 PE polyester color-coated sheet has good adhesion, rich color, wide range in formability and outdoor durability, medium chemical resistance, and low cost. The advantages of PE polyester color-coated board are mainly cost-effective, and it is recommended to use PE polyester color-coated board in a relatively friendly environment;

2. High weather resistance coating (HDP) color coated board;
 HDP high weathering color coated board has excellent color retention and anti-ultraviolet performance, excellent outdoor durability and chalk resistance, good paint film coating adhesion, rich colors, and excellent cost performance. The most suitable environment for high-weather-resistant HDP pressure-type color-coated rolls is harsh weather environments, such as plateaus and other areas with strong ultraviolet rays, we will recommend the use of HDP high-weather-resistant pressure-type color-coated rolls;

3. Silicon modified coating (SMP) color coated board;
 The hardness, abrasion resistance and heat resistance of the SMP silicon-modified polyester color-coated sheet are good; as well as good external durability, chalk resistance, gloss retention, general flexibility, and moderate cost. The most suitable environment for SMP silicon-modified polyester embossed color-coated coils is high-temperature workshops. For example, steel mills and other environments with high indoor temperatures are generally recommended to use SMP silicon-modified polyester embossed color-coated coils;

4. Fluorocarbon coating (PVDF) color coated board;
PVDF Fluorocarbon Color Coated Sheet has excellent color retention and UV resistance, excellent outdoor durability and chalk resistance, excellent solvent resistance, good formability, dirt resistance, limited color, and high cost. The high corrosion resistance of PVDF profiled color-coated coils. Many workshops with strong corrosive environments will choose PVDF profiled color-coated coils, and there are often humid sea breezes at the seaside, which are more corrosive.

Our company produces high quality color coated steel, and imposes strict quality control over the prepainted steel coils. We use good quality hot-dip galvanized steel coil or Alu-Zinc coated steel coils as base sheet and strictly select coated paints, which have won public praise in China. Moreover, we have attained ISO9001 certification, which gives quality promise to customers and competitive advantage for our company.
