Black iron and galvanized pipe and fittings are made from which material?

Explanation:
These pipes are steel. The term “black iron” refers to a steel pipe with a dark, oxide finish, and galvanized pipe is steel coated with zinc to prevent corrosion. Copper and aluminum are different metals used for other plumbing systems, but the base material for both black iron and galvanized pipes and fittings is steel.
