Color coated galvanized sheet has been widely used in daily life. The service life of color galvanized sheet with the same amount of zinc plating will be very different in different regions and different parts of use. Therefore, according to different situations, it is also different when it is handled. So what is the reason? Let's learn about it next.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 its service life will be reduced if it is soaked by rain for a long time, or where the temperature difference between day and night is too large and easy to condense. Buildings or plants made of color coated galvanized sheet often have a long service life when washed by rain. Otherwise, they will be affected by sulfur dioxide gas, salt and dust. Therefore, in the design, the greater the inclination of the roof, the less likely it is to accumulate dust and other dirt, and the longer the service life; Areas or parts that are not frequently washed by rainwater shall be washed with water regularly. It shall be stored in a clean environment. In order to avoid corrosive intervention, the ground of the storage site shall be flat and have sufficient bearing capacity. Except for some different types of color coated galvanized sheet, it is not suitable to put it directly on the ground, but on the rubber pad or bracket device. The storage place must be dry and ventilated. When it is placed again, the position should be selected to reduce movement as much as possible.
