Galvanized square pipe is a hollow square section steel pipe with a square section shape and size made of hot-rolled or cold-rolled galvanized steel strip or galvanized coil as a blank, cold-bent and formed by high-frequency welding. , Or a galvanized rectangular tube made of cold-formed hollow steel pipe prepared in advance and then processed by hot-dip galvanizing.
Galvanizing has stronger protective effect and strong corrosion resistance. The entire structure is made of zinc to form dense quaternary crystals, which form a barrier on the steel plate, thus 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 for sacrificial protection on the cut edges, scratches and scratches of the coating, zinc forms an insoluble oxide layer and exerts a barrier protection function.
