Round Black Steel Pipe

Round Black Steel Pipe is a high-quality carbon steel pipe with a black surface finish, manufactured through welding processes such as ERW (Electric Resistance Welding). It is widely used in construction, structural engineering, machinery manufacturing, transportation systems and industrial applications. As a professional black steel pipe manufacturer and supplier, we provide ERW black round steel pipes in various outer diameters, wall thicknesses and lengths. Our products are available in different steel grades, including Q195, Q235, Q345, ASTM A53 Grade A/B, API 5L Grade B, S235JR, S355JR and other equivalent materials. The pipes are manufactured according to international standards such as ASTM, EN, DIN, JIS, GB, ISO and BS. Black round steel pipes feature high strength, good weldability, accurate dimensions and reliable mechanical performance. Compared with galvanized pipes, black steel pipes have a natural mill finish and are commonly used in applications where surface coating is not required or additional painting and coating will be applied after installation. Our ERW black steel pipes are widely used for steel structures, scaffolding, mechanical equipment, agricultural facilities, water and gas transportation, fencing, and general industrial projects. We offer customized solutions with different specifications, surface conditions and packaging options according to customer requirements. With strict quality control, advanced production facilities and professional export experience, we supply reliable black round steel pipe products to customers worldwide.
