The film-coated color steel plate realizes the combination of thermal insulation and long-lasting corrosion resistance. The sturdiness of the product also plays a role in heat insulation, lasting corrosion resistance and other properties, and can adapt to complex and harsh climate environments.
The corrosion time of color steel tiles in a long-term humid or corrosive environment will be greatly shortened. This is because from a microscopic level, there are many pinholes in the coating film of the color-coated board. Moisture, oxygen, corrosive ions, etc. pass through the pinholes to contact the substrate to form oxidative corrosion and electrochemical corrosion. It is especially obvious in corrosive environments, such as coastal environments, chemical plants, steel plants, pickling plants, casting plants, farms, etc., where the corrosion rate will be greatly accelerated. Most color steel tiles will rust and leak in 1-2 years.
