A galvanized steel pipe is a steel tube coated with a protective layer

A galvanized steel pipe is a steel tube coated with a protective layer of zinc through“hot-dip galvanizing”or“electro-galvanizing”processes. The zinc coating prevents corrosion and rust, significantly extending the pipe’s lifespan. These pipes are widely used in environments exposed to moisture, chemicals, or outdoor weather conditions.
