Pure zinc coating of hot dip galvanized steel pipe to improve corrosion resistance

　　Hot dip galvanized steel pipe is made on the basis of ordinary steel pipe. In addition, the zinc coating is well combined with the substrate. In this process, there are many processes and processes. The alloy layer and pure zinc layer on the surface can greatly improve the corrosion resistance of steel pipes.

　　First, the corrosion resistance of hot-dip galvanized steel pipe is relatively high. In humid environment, galvanized pipe must be corrosion resistant. The method of hot galvanizing is not only to improve the quality, but also to continuously strengthen the requirements for corrosivity, so it is more suitable for the construction process.

　　Second, the hot-dip galvanized steel pipe has high strength, good performance and light weight, which are the three advantages that need to be possessed in the construction process

　　Third, hot-dip galvanized steel pipe hot-dip galvanized material is mainly a new process used in steel processing. At present, in the promotion of processing technology, such steel will have good properties. The price in the market is reasonable, which is the key to recognition.
