The hot dip galvanized square pipe is a square steel tube with a surface galvanized. The square tube made by welding the steel plate or steel strip after being crimped and formed is formed in a hot-dip galvanizing bath through a series of chemical reactions. The production process of the tube is simple, the production efficiency is high, and the variety specifications are many, but the general strength is lower than the seamless square tube.

The hot dip galvanized square pipe has good process properties such as strength, toughness, plasticity and welding and has good ductility. Since the alloy layer and the steel base are firmly attached, it can perform various forming processes such as cold punching, rolling, drawing, and bending without damaging the galvanized layer. This square pipe is very suitable for general processing such as drilling, cutting, welding, cold bending and other processes. And the surface of the product after hot-dip galvanizing is bright and beautiful, and can be directly used for engineering according to requirements.
Hot dip galvanized square pipes are often used in glass curtain walls, power towers, communication grids, water and gas transmission, wire casings, houses, bridges, metal structures, power transmission, etc. due to their excellent performance.
Galvanized has strong protection and strong corrosion resistance. The entire structure consists of zinc, forming a dense quaternary crystal that forms a barrier on the steel sheet, thus effectively preventing the penetration of corrosion factors. When zinc is sacrificed in trimming, scratching, and scratching of the coating, zinc forms an insoluble oxide layer that acts as a barrier.
