Color-coated steel plate is also known as color-coated steel plate and color-coated steel plate. Color-coated steel plate is a kind of color-coated steel plate. The paint is coated by roller coating method, and the product is made by baking and cooling after conversion treatment. The substrates of color-coated plates include cold-rolled substrates, hot-dip galvanized substrates, electro-galvanized substrates, and aluminized zinc substrates. The types of topcoat coating of color-coated plates can be divided into polyester, silicon-modified polyester, vinylidene fluoride, high weather-resistant polyester, etc. The production process has been developed from one coating and one baking to two coating and two baking. There is also a three-coating and three-baking process. There are many colors of color-coated boards, such as white gray, sea blue, orange, sky blue, crimson, brick red, ivory white, porcelain blue, etc. The surface state of color-coated boards can be divided into ordinary coated boards, embossed boards and printed boards. The market uses of color-coated boards are mainly divided into construction, home appliances and transportation.

The color-coated steel plate has beautiful appearance, light weight, good corrosion resistance, and can be directly processed, providing a new type of steel instead of wood, which has the advantages of high construction efficiency, energy saving and pollution prevention.

1. Color-coated boards are widely used and have the characteristics of no pollution, weather resistance, corrosion resistance and high processability. Color-coated boards are generally widely used in industry, construction, home appliances, packaging, machinery and other fields. Involving processing, transportation, interior decoration, medical and automotive industries.

2. The utilization rate of color-coated panels in home appliances is 31%, while the use in construction accounts for 63%, which is indispensable in the construction industry. Other aspects are less used, about 6%. The coated plate with galvanized steel plate as the substrate has the function of protection and isolation, which can not only prevent the steel plate from rusting, but also extend the service life by 50% compared with before, and has a stronger protective effect.

3. Different regions and use parts, even if the same number of galvanized, painted and color-coated sheets with the same coating thickness are used, their service life is more different. In industrial areas and coastal areas, due to exposure to sulfur dioxide gas or salt in the air, the corrosion rate will be accelerated, thereby affecting the service life. In the rainy season, the coating will quickly corrode after being wetted by rainwater for a long time, thereby reducing the service life.

4. Buildings and workshops with color-coated panels can prolong their service life if they are often initialized by rain. Otherwise, they will be more susceptible to sulfur dioxide, salt and dust. Therefore, when designing, the inclination of the roof should be increased. The larger, the less dirt such as dust accumulates, and the longer the service life. For parts and areas that are not often initialized by rain, they should be cleaned regularly.
