The galvanized square pipe is a hollow square section steel pipe with a square section shape and size, which is made of hot-rolled or cold-rolled galvanized strip or galvanized coil as a blank, cold-formed, and high-frequency welded. Cold-formed hollow steel pipe, galvanized rectangular pipe processed by hot-dip galvanizing.

Galvanized for greater protection and greater corrosion resistance. The entire structure is made of zinc, which forms dense quaternary crystals that form a barrier on the steel plate, thus effectively preventing the penetration of corrosive factors. Corrosion resistance comes from the strong protective function of the barrier layer of zinc. When zinc is used for the sacrificial protection of cut edges, nicks and nicks in the coating, zinc forms an insoluble oxide layer that acts as a barrier protection.

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. Mainly used in construction, curtain wall, steel structure engineering, machinery manufacturing, solar power generation bracket, steel structure engineering, electric power engineering, shipbuilding, power plant, automobile chassis, glass curtain wall, agricultural chemical machinery, airport, etc.
