Product Description
Erw Galvanized Steel Pipe is a pipe coated with zinc. This coating can protect the galvanized pipe from corrosion and rust, so as to prolong the service life and improve the reliability of the galvanized tube. Zinc is used as a sacrificial layer, which will rust in front of the metal below it, keeping the integrity of the pipe longer than ordinary pipes. In addition, even if the zinc layer is scratched or damaged, it can still protect the metal under it. Hot dip galvanized steel pipes are widely used in construction, machinery, coal mining, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, exploration machinery, greenhouse construction and other manufacturing industries.
