Color-coated coils are known to everyone in the construction industry, and the demand for color steel coils in the market is also increasing. The service life of a product is one of the most important reasons for consumers to choose a product, so how long is the service life of the color-coated coil?
Due to the different uses and use environmental conditions of color-coated coils, there are many factors that affect their service life. According to the use function, the service life of color-coated coils can be divided into the following types:
1) The service life of coating refurbishment: about 12-20 years, which refers to the use time for most of the defects such as delamination and rust on the surface of the color-coated coil, which causes further corrosion of the substrate.
2) Ultimate service life: about 20 years, refers to the long-term use of color-coated coils without refurbishment until serious corrosion occurs and they can no longer be used.
3) Decorative service life: about 8-12 years, referring to the subjective fading, chalking, cracking, and partial peeling of the coating on the surface of the color-coated coil. It has an impact on the image and aesthetics of the building, but it has not yet reached the point where the coating has lost its protective effect.
