Color steel plate, cold rolled steel

In industrial or coastal areas, due to the action of sulfur dioxide gas or salt in the air, the corrosion rate accelerates and the service life is affected. During the rainy season, coatings that are soaked in rainwater for a long time or are prone to condensation in areas with large temperature differences between day and night will quickly corrode and have a reduced service life. Buildings or factories made of colored coated steel plates often have a longer service life when washed by rainwater. Otherwise, their use may be affected by the effects of sulfur dioxide gas, salt, and dust. Therefore, in design, if the inclination of the roof is greater, it is less likely to accumulate dust and other pollutants, and the service life is longer; For areas or parts that are not frequently washed by rainwater, regular water flushing should be carried out.
