Hot-dip galvanized pipe is a method that uses high-temperature steam heated to about 450°C to melt the surface of the base material and then immerses it in a galvanizing pool with a specified formula, thereby coating the surface of the steel pipe with a layer of zinc. Due to the large amount of heat generated during the high-temperature hot-dip galvanizing process, the applicable temperature of hot-dip galvanized pipes is much higher than that of electro-galvanized pipes, generally between -40°C and 200°C.
Hot-dip galvanized pipes have a wide range of applications, such as fire protection, electric power, highways, curtain walls, construction, machinery manufacturing, shipbuilding, solar power generation brackets, steel structure engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, etc. field.
