The durability of the color coated steel plate is the time before the coating get hardened and powdered, that is mean that the coating do not cracked and fall off. The main influencing factors are the environment of the color steel plate and the paint and technology of the painting. Therefore, Using different types of paint, it’s life is also different. According to reports, which is used on outdoor, due to the pollution and the chance of climate conditions, when the organic coating long-term exposure to sunlight lead to hardening and powder, also because of moisture lead to bulging and get loose,ultimately gradually lostthe protective effect of the coating, Then need to re-paint maintenance treatment. The use of time before processing as a service life is another concept of service life. According to this concept, for the level of coating development , that it is possible to determine that the service life of the PVDF paint plate coating in heavily polluted climatic environment is around 20 years, rural areas for 30 to 40 years.
