Advantages
a. 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 pipes, galvanized steel round pipe corrodes much slower, extending the life of the pipes
b. Lower cost than stainless steel
c. Lowest long-term cost
d. Reliable performance
e. Excellent resistance to mechanical damage
