2023-12-19

Q345 Galvanized Square Steel Pipe is made of hot-rolled or cold-rolled Galvanized Steel strip or galvanized coil welded by high-frequency cold bending. , or a galvanized square steel tubes made by hot-dip galvanizing the pre-cold bent hollow steel tubes.
Galvanized square pipes use
Since the galvanized square steel tube is galvanized on the square steel pipes, the application range of the galvanized square tube has been greatly expanded compared with the square tube. Mainly used in curtain wall, construction, machinery manufacturing, steel structure engineering, shipbuilding, solar power generation support, steel structure engineering, electric power engineering, power plant, agricultural chemical machinery, glass curtain wall, automobile chassis, airport, etc.

Galvanized for greater protection and greater corrosion resistance. The entire structure is composed of zinc, which forms dense quaternary ammonium salt crystals and forms a barrier on the Steel Plate, thereby effectively preventing the penetration of corrosion factors. Corrosion resistance is due to the strong protective function of the zinc barrier. When zinc is used for sacrificial protection of cut edges, scratches and coating scratches, zinc forms an insoluble oxide layer that acts as a barrier protection
