According to the shape, it can be divided into galvanized square tube and galvanized round tube. It has high production efficiency, light weight, high degree of automation, easy to implement mechanized and automated operating procedures, and product quality is stable and reliable.

Galvanizing has stronger protective effect and strong corrosion resistance. The entire structure is made of zinc, forming a dense quaternary crystal. This crystal forms a barrier on the steel plate, thus effectively preventing corrosion factors from penetrating. Corrosion resistance comes from the strong protective barrier layer of zinc. When zinc provides sacrificial protection on trimmed edges, scratches, and scratched parts of the coating, the zinc forms an insoluble oxide layer and plays a barrier protective function.

Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, and as oil heaters and condensators in chemical coking equipment. Pipes for coolers, coal distillate wash oil exchangers, pipes for trestle pipe piles, and support frames for mine tunnels, etc. Hot-dip galvanized steel pipes are widely used in construction, machinery, coal mines, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, greenhouse construction and other manufacturing industries.
