Products Description
The base body of the galvanized square pipe and the molten weld metal directly form a corrosion-resistant structural tight layer. Since the existence of this structural tight layer can effectively prevent the molten weld metal from intergranular corrosion (near the welding heat affected zone), therefore It has good resistance to atmospheric corrosion and high temperature oxidation resistance; at the same time, due to the protective effect of the galvanized layer, the surface of the component has a very smooth, dense and strong protective film, which greatly improves the adhesion of the coating; in addition, it is moisture-proof and anti-corrosion properties.Don't miss this opportunity!
