In rainy season, the surface of building hanging basket often corrodes. In this case, the customer's first reaction is that this is caused by the poor quality of the building hanging basket itself. In fact, the reason why the surface of the building hanging basket will be corroded is actually because the user's storage method is improper, and the other party must put the building hanging basket in a humid environment for a long time, which will lead to the pollution and corrosion of the paint on the outer layer of the building hanging basket. After a long time, the corrosion degree of building hanging baskets will become more and more serious, which will directly shorten the service life of building hanging baskets, especially for users in the north, who buy building hanging baskets in summer and put them on hold after use, and will be easily corroded in winter.
