Difference between cold-galvanized steel pipe and hot-dip galvanized steel pipe Galvanized steel pipe types Galvanized steel pipe include two kinds: 1. Hot dipped galvanized steel pipe. 2. Cold galvanized pipe, also called electric galvanized pipe. Galvanized steel pipe sizes and specifications Nominal diameter (inch): 1/2~4 Nominal wall thickne...

Cold galvanized steel pipe 1.“Cold plated” or “plating”, ie the zinc salt solution by electrolysis, to the plating on the coating, generally do not have heating, small amount of zinc, the wet environment is very easy to fall off. 2. Cold galvanizing is the physical address, just brush the surface layer of zinc, the zinc layer is easy to fall off...
