Color coated plate is widely used for good corrosion resistance

The color coated board has light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed. It provides a new type of raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, electrical industry, etc. Wood, efficient construction, energy conservation, pollution prevention and other good results. The galvanized steel plate is used as the color-coated plate of the substrate. In addition to the zinc protection, the organic coating on the zinc layer serves as a covering effect to prevent the steel plate from rusting and has a longer service life than the galvanized steel plate. The service life is 50% longer than galvanized steel. However, in different regions and different parts of use, the use of the same galvanizing amount, the same coating, the same coating thickness of the color coated board, the service life will be very different. For example, in industrial areas or coastal areas, due to the action of sulfur dioxide gas or salt in the air, the corrosion rate is accelerated and the service life is affected. During the rainy season, the coating is wetted by rain for a long time, or it is corroded faster and the service life is reduced in the parts where the temperature difference between day and night is too high and condensation is formed. Buildings or buildings made of color-coated plates are often subjected to rainwater for a long service life, otherwise they are affected by the action of sulfur dioxide gas, salt and dust. Therefore, at the time of design, if the inclination of the roof is larger, the dirt is less likely to accumulate dirt and the like, and the service life is longer; for those areas or parts that are not washed frequently by rain, it should be washed regularly with water.
