    The application of pregalvanized square pipe and hot dipped galvanized square pipe

    Use of galvanized square tube Since the galvanized square tube is galvanized on the square tube, the application range of the galvanized square tube has been greatly expanded compared with the square tube. It is mainly used in curtain walls, construction, machinery manufacturing, steel construction projects, shipbuilding, solar power generation brackets, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, etc.

    What is the difference between hot dip galvanized pipe and pre-galvanized pipe

    pre-galvanized steel tube is a steel tube that is galvanized a steel strip before it is formed and welded into a tube, but pre-galvanized pipe are processed with galvanized steel strip for one-time forming, and the anti-corrosion time is not as long as that of hot-dip galvanizing, therefore, it is used indoors or in dry places.

    Hot-dip galvanized pipe is processed from black pipes,then go to galvanizing. After a high temperature of 1000 degrees, generally thin wall thicknesses are not hot-dip galvanized.Hold superior corrosion resistance strength.
