Galvanized square and rectangular tube is a square section steel tube that has been hot-dip galvanised. A galvanized layer on the surface of the galvanized square and rectangular tube effectively prevents oxidation on the inner and outer surface of the tube, thus improving the corrosion resistance of the tube. This makes the galvanized square and rectangular tube a long service life. Secondly, the welding properties of galvanized square and rectangular tube are not significantly affected by the hot-dip galvanizing treatment. Therefore, it can be easily welded with other steels and is suitable for various welding processes. In addition, galvanized square and rectangular tube has high strength and wear resistance as it is formed by processing steel, and can withstand large external forces and pressures. In addition, the surface of galvanized square and rectangular tube is covered with a uniform, smooth and bright galvanized layer, which has good decorative and aesthetic properties. And galvanized square and rectangular tube can be bent and processed according to the need, with high plasticity.
