Galvanized square pipe is a kind of hollow square section steel pipe made of hot rolled or cold rolled galvanized strip steel or galvanized coil steel as blank by cold bending forming and then by high-frequency welding made of square section shape size; Or the cold-formed hollow steel tube made in advance and then processed by hot dip galvanized galvanized square pipe.
Galvanized its protective effect is stronger, strong corrosion resistance. The entire structure is made of zinc, forming dense tetrad crystals that form a barrier on the steel plate, thus effectively preventing corrosion agents from penetrating. Corrosion resistance from zinc barrier layer protection. When zinc sacrificial protection on cut edges, scratches and coating abrades, zinc forms an insoluble oxide layer and acts as a barrier protection.
Galvanized square pipe use
Mainly used in curtain wall, construction, machinery manufacturing, steel construction projects, shipbuilding, solar power generation support, steel structure engineering, power engineering, power plant, agricultural and chemical machinery, glass curtain wall, car chassis, airport and so on.
