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 covering and isolation function, which can prevent the steel plate from rusting, and has a longer service life than galvanized steel. According to the introduction, the coating The service life of the steel plate is 50% longer than that of the galvanized steel plate. However, in different regions and different parts of use, the service life of color coated plates with the same galvanizing amount, the same kind of paint, and the same coating thickness will be very different. For example, in industrial areas or coastal areas, due to the effect 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 wetted by rain for a long time, or where the temperature difference between day and night is too large and easy to condense. Buildings or workshops made of color-coated steel plates often have a long service life when they are washed by rain, otherwise they will be affected by the effects of sulfur dioxide gas, salt and dust. Therefore, when designing, if the slope of the roof is larger, it will be less likely to accumulate dust and other dirt, and the service life will be longer; those areas or parts that are not frequently washed by rain should be washed regularly with water.

Color steel plates are widely used. It has the characteristics of non-polluting, excellent weather resistance, corrosion resistance and high processing. Color steel plates are widely used in construction, home appliances, transportation, packaging, mechanical processing, interior decoration, medical treatment, automobile industry, etc.
