What is black steel?

Black steel is made of steel that has not been galvanized. Its name comes from the scaly, dark-colored iron oxide coating on its surface. Since it has a dark color surface that is form by iron oxide during the manufacturing process, it is called black steel pipe.

Does galvanized steel rust?

Galvanized steel takes a long time to rust, but it will eventually rust. This type is carbon steel that has been galvanized, or coated, with a thin layer of zinc. Like aluminum, zinc is highly reactive to oxygen in the presence of moisture, and the coating prevents the iron in the steel from further oxidation.

What is black steel pipe made of?

Black steel pipe is made of steel that has not been galvanized. Its name comes from the scaly, dark-colored iron oxide coating on its surface. It’s used in applications that don’t require galvanized steel.

Can you mix galvanized and black pipe?
