carbon steel pipe

Carbon steel pipes  are used in the most critical engineering applications and also in certain applications in the automotive sector. In addition, some of the value-added Carbon Steel products include steel for LPG cylinders, API grade, corrosion resistant steel, critical structural application steel, boiler quality, auto grades, precision tubes and medium/high carbon grades, among others.
