Galvanized square pipe is a hollow square section steel pipe made of hot-rolled or cold-rolled galvanized strip steel or galvanized coil steel, which is formed by cold bending processing and then high-frequency welding, or a galvanized square pipe made of pre made cold bending hollow steel pipe and then hot-dip galvanizing processing.
Galvanized square pipes are divided into hot dip galvanized square pipes and cold dip galvanized square pipes in terms of production technology. It is precisely because the processing of these two types of galvanized square pipes is different that they have many different physical and chemical properties. Overall, they have many differences in strength, toughness, and mechanical properties.
Galvanizing has a stronger protective effect and strong corrosion resistance. The entire structure is composed of zinc, forming a dense quaternary crystal, which forms a barrier on the steel plate, effectively preventing corrosion factors from penetrating. The corrosion resistance comes from the strong protective function of the barrier layer of zinc. When zinc is used as sacrificial protection in areas such as cuts, scratches, and coating scratches, it forms an insoluble oxide layer that serves as a barrier protection function.
