The coating or plating of ordinary roof tiles generally has no protection and is susceptible to wear and tear. Therefore, the steel plate will be exposed to moisture, acidic or alkaline environments for a long time, and will be easily affected by corrosive substances such as salts and acids, resulting in oxidation reactions on the surface of the steel plate. , forming rust and corrosion, affecting lifespan.
In order to solve this problem, Himei waterproof tiles add anti-corrosion layers to both the front and back of the steel plate during production. The anti-corrosion ability exceeds 25 years, providing a good solution for roof anti-corrosion.
