What is Black Steel Pipe?
Black steel pipe is made from the hot-rolled or cold-rolled coil that has been treated with a pickling solution to remove rust and oil, then heated and coated with zinc to protect it from corrosion and oxidation. It's a common material used in industrial applications such as plumbing, heating and cooling systems, machinery parts, construction projects, electrical conduit systems, and sprinkler systems.
