Welded Carbon Black Structure Transportation Steel Pipe Tube

Black steel is the uncoated steel. When steel pipe is forged, a black oxide scale forms on its surface to give it the finish which is seen on this type of pipe. Because black steel is subject to rust and corrosion, the factory also coats it with protective oil. Those black steel are used for manufacturing pipe and tube, which will not rust for a long time and requires very little maintenance.

Surface treatment: Galvanized, oil coating, lacquering
