Galvanized Steel Pipe is most commonly used for outdoor construction like fences and handrails, or for some interior plumbing. Best quality hot dip galvanized steel pipe/HSS/rectangular tube is also sometimes called galvanized iron pipe. Galvanized steel pipe has been coated with a layer of zinc. The zinc provides a barrier against corrosion so that the pipe may be exposed to the outdoor environmental elements.Galvanized Steel Pipe The protective barrier proves equally effective against damage from indoor humidity.Best quality hot dip galvanized steel pipe/HSS/rectangular tube is covered with a zinc material to make the steel pipe more resistant to corrosion.
