Galvanized pipe, also known as galvanized steel pipe, is a pipe product that is coated with a layer of metallic zinc on the surface of ordinary steel pipes.

The main purpose of galvanized pipe is to prevent corrosion and rust, thereby extending the service life of the steel pipe. Galvanized pipes are divided into two types: hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing has a thicker, uniform coating and strong adhesion, while electro-galvanizing has a lower cost and a smoother surface.
