Manufacture Process

Benefits of galvanized pipe
Because the pipes are galvanized, it is protected from rust and corrosion. Steel rusts after interacting with water or moisture in the air over time. By adding a coating of zinc to the tubing, galvanized steel round tubing corrodes much slower, extending the life of your tubing.
