　　Galvanized steel pipes are usually red, some are yellow, but some customers reported to us galvanized steel pipes after a period of time will change color, generally white. This is because the composition of the Hot Dipped Galvanized Steel Pipe is determined by its chemical properties, galvanized steel pipe is mainly composed of zinc, it is easy to react with oxygen in the air, thereby oxidizing into thin films.

　　In order to prevent this from happening, we must keep it well and keep it as dry and ventilated as possible. How to maintain the galvanized steel pipe?

　　The galvanized steel pipe should pay attention to ventilation and drying when stacking products, should be amphoteric zinc metal, more active, so it is easier to corrosion in general humid environment, because slight corrosion of the galvanized steel pipe will also occur larger color difference, affecting the appearance of the product. As long as good ventilation can be guaranteed, even if it rains, but timely drying, galvanized products will not have much impact.

　　No acid, alkali, salt, cement and other corrosive substances should be stacked in the storehouse. Different types of galvanized steel pipe should be stacked separately to prevent confusion and contact corruption, and can be placed in a well-ventilated shed, but must be uprooted and laid underneath; Warehouses should be selected according to geographical conditions, generally using ordinary closed warehouses, that is, warehouses with roof walls, doors and windows tightened, ventilation devices; warehouses on sunny days to be necessary. Please note that ventilation should be closed and wet weather should be closed.

　　Galvanized steel pipe to prevent oxidation discoloration, once the discoloration occurs, there may be chemical changes, many properties are easy to lose, it is recommended that we should still galvanized steel pipe properly preserved.
