Galvanized tubes, also known as galvanized steel tubes, are mainly divided into two types: hot-dip galvanizing and electro-galvanizing (cold-dip galvanizing). Hot-dip galvanizing is a process in which a steel pipe substrate undergoes a complex physical and chemical reaction with the molten plating solution to form a corrosion-resistant, tightly structured zinc-iron alloy layer with strong corrosion resistance. The commonly used specifications are +12.5~+102mm2. In contrast, the amount of galvanizing in electro-galvanizing (cold-dip galvanizing) is less, only 10-50g/m², and its corrosion resistance is much worse than that of hot-dip galvanized pipes.
