What is a Galvanized Steel Pipe?

A galvanized steel pipe is a carbon steel pipe coated with a protective zinc layer through galvanization, providing superior corrosion resistance and extended service life. Available in both Hot-Dip Galvanizing (HDG) for heavy-duty protection and Electro-Galvanizing (Cold Galvanizing) for precision applications.
