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

Explanation:
Steel. Black iron pipe is actually a type of steel pipe, and galvanized fittings are steel parts with a zinc coating to prevent corrosion. The term “iron” in the name is historical, but the material is steel for the strength and durability needed in these piping applications. Aluminum and copper are used in other plumbing applications, but not for black iron pipe or galvanized fittings.
