Carbon steel tubes, available in rectangular, square, and round shapes, are widely used in structural, industrial, and mechanical applications due to their strength, durability, and versatility. We stock these tubes in A513 andA500 grades, both of which are known for their excellent weldability, formability, and reliability in heavy-duty environments.A513 tubing is typically used for precision applications, offering high tensile strength and tight tolerances, while A500 tubing is ideal for structural applications, providing a solid foundation for frames, supports, and general construction purposes. These carbon steel tubes are perfect for everything from structural components and scaffolding to transportation and manufacturing equipment.
