Hot-dip Galvanized square steel pipe is made of steel plate or steel strip after curling molding of the square tube in the hot-dip galvanizing pool through a series of chemical reaction molding of the square tube, can also be through hot-rolled or cold-rolled galvanized steel belt through cold bending, and then high-frequency welding of a hollow square section steel pipe. Pipe production process is simple, high production efficiency, variety specifications, less equipment, but the general strength is lower than seamless square tube.
