Both galvanized square tube and galvanized rectangular pipe are cold-formed hollow steel, and the surface is coated with hot-dip galvanized layer or electro-galvanized layer, which can increase the corrosion resistance of galvanized steel pipe and prolong
Galvanized square tube: hot-rolled or cold-rolled galvanized steel strip or galvanized coil as the blank, cold-formed and high-frequency welded, hollow square steel with square cross-sectional shape and size. Or a galvanized square tube made by hot-dip galvanizing the pre-cold bent hollow steel tube.
Galvanized rectangular pipe: It is a name for square pipe and rectangular pipe; it is a galvanized steel pipe with the same side length; it is a square pipe made of galvanized steel strip after processing. Generally, the galvanized steel strip is welded to form a round tube through a series of processes such as unpacking, flattening, and crimping, and then rolled into a rectangular tube from the round tube, and then cut to the required length. Galvanized rectangular pipes are generally 50 pieces per package.
Galvanized square tube and galvanized rectangular pipes are also known as square and rectangular cold-formed hollow sections, referred to as square tubes and rectangular tubes.
Both the galvanized square tube and the galvanized rectangular pipe have been galvanized on the tube, so their application range 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.
