Z120 Galvanized Pipe/Tube

Brief Introduction：

Galvanized steel pipe, also known as galvanized welded steel pipe, is made of hot-rolled or cold-rolled strip steel as the base material, which is bent and welded into a steel pipe, and then subjected to galvanizing treatment on the surface. According to the galvanizing process, it can be divided into hot-dip galvanized pipes and electroplated galvanized pipes. The hot-dip galvanized layer is thick and has strong corrosion resistance. It is widely used in fields such as construction, machinery manufacturing, chemical engineering, and power
