Galvanized Steel Pipe can be made into a strong plumbing or tubing material -- one that resists corrosion from exposure to water or the elements.BS1387 EN10255 ASTM A53 B Hot dipped Galvanized steel pipe, GI pipes has been used used for water-supply pipes or as a strong tubing for outdoor applications.

Galvanized Steel Pipe is most commonly used for outdoor construction like fences and handrails, or for some interior plumbing. BS1387 EN10255 ASTM A53 B Hot dipped Galvanized steel pipe, GI pipes 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.BS1387 EN10255 ASTM A53 B Hot dipped Galvanized steel pipe, GI pipes is covered with a zinc material to make the steel pipe more resistant to corrosion.
