As a new type of raw material, the appearance of color coated sheet has brought many conveniences to construction, vehicle manufacturing, private, electrical and construction industries. It can not only replace wood with steel, but also save energy, improve construction efficiency and avoid environmental pollution.

But we should try our best to avoid such mistakes as scratches in the production process. Once we find such a situation, how can we repair it? Due to the doubts about the resin material of the paint, the primer is not well connected with the passivation layer. Till both ends of the steel plate are fixed. A simple and effective method is to use a pair of clamps to clamp the overlapping steel plates at the place of residence. Dust will affect the surface quality of finished color coated sheets, especially the quality defect of aging explosive paint of color coated sheets

Classified color coated panels should be placed on rubber pads, pads, brackets and other devices, and the strap lock should be upward, not directly on the ground or on the means of transport. If the color steel plate is scratched and installed, it may lack aesthetics, which may have a corresponding impact on the continuous use of the color steel plate, especially in some acid-base, salt fog environment. Therefore, when we encounter such a problem, we first need to solve such a problem.

If the scratched area of the color steel plate is not large, it can be stored with the rust-proof oil after lightly throwing the cloth wheel, and then proceed to a subsequent painting process. In addition, the painting of the color steel plate also needs to be degreased. If the stained steel plate has deep rust spots and large area of injury after scratching, then we must first deal with the surface of the stained steel plate, and then repair it.
