Product use of color-coated board

The color-coated steel plate using galvanized steel plate as the substrate, in addition to zinc protection, the organic coating on the zinc layer plays a role of covering and isolation, which can prevent the steel plate from rusting and has a longer service life than the galvanized steel plate. According to reports, the coating The service life of steel plate is 50% longer than that of galvanized steel plate. However, in different regions and different parts of use, the service life of color-coated boards with the same amount of galvanizing, the same coating, and the same coating thickness 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. In the rainy season, the coating will be corroded quickly and the service life will be reduced if the coating is soaked by rain for a long time, or the parts where the temperature difference between day and night is too large and easy to condense. Buildings or workshops made of color-coated steel plates have a long service life when they are often washed by rainwater, otherwise, they will be affected by the action of sulfur dioxide gas, salt and dust. Therefore, when designing, if the inclination of the roof is greater, it is less likely to accumulate dust and other dirt, and the service life will be longer; for those areas or parts that are not frequently washed by rainwater, they should be washed with water regularly.
