Color aluminum plate life type

Due to the different uses and environmental conditions of the color aluminum plate, there are many factors affecting its service life. According to the function of use, the service life of the color coated plate can be divided into the following types:
(1) Decorative service life refers to defects such as subjective fading, chalking, cracking, and partial peeling of the surface of the color coated board. It affects the image and aesthetics of the building, but it has not yet reached the extent that the coated piece loses its protective effect.
(2) The service life of the coating renovation refers to the occurrence of most delamination, rust spots and other defects on the surface of the color steel plate, resulting in the use of the substrate for further corrosion.
