The specific service life of color-coated steel plate has a great relationship with the material itself, such as zinc layer on the surface, paint type and paint coating thickness.

Its topcoat coating classification mainly includes PE polyester color plate (service life is 5-10 years, characterized by good adhesion, wide range in formability and outdoor durability, and medium chemical resistance).

PVDF fluorocarbon color plate (used for more than 20 years, characterized by extraordinary stability, can maintain the stability of various properties in acid, alkali and polluted environment; Excellent durability, fluorocarbon color plate can still maintain good color and luster outdoors for 20 years; Excellent processability, the painted color plate has high flexibility and impact resistance, and can also be post-embossed)

HDP high weather-resistant polyester color plate (the service life is 10-15 years, which is characterized by the different resin molecular structure between high-performance polyester and ordinary polyester, and the high-performance polyester has better performance of resisting ultraviolet destructive power and better durability, and its main performance is between polyester and fluorocarbon).

SMP silicon modified color plate (the service life is 10-15 years, which is characterized by good hardness, wear resistance and heat resistance of the coating film, good external durability and non-pulverization, but limited gloss retention and flexibility), and the specific service life of the silicon modified color plate is also closely related to the service environment.
