Galvanized pipe is steel pipe that has been coated with a layer of zinc to protect it from corrosion. This process, called galvanization, involves immersing the steel pipe in molten zinc to create a durable and corrosion-resistant barrier. Galvanized pipes are commonly used in plumbing, water distribution, and gas supply systems, as well as for structural applications such as fences, handrails, and scaffolding. The zinc coating helps prevent rust and corrosion, extending the lifespan of the pipe.
