H-beam welding lines are used to assemble and weld steel plates into H-beams for heavy steel structure production. From assembly to welding, flipping, transfer, and straightening, each step follows the next in sequence until the H-beam is completed. After years of refinement and use in real production settings, these structural steel processing lines have become a widely used solution in steel structure fabrication and are now operating in more than 1,000 customer facilities worldwide.

As a newer generation of structural steel welding lines independently developed by Yangtong, H-beam welding lines are available in three standard sizes based on the maximum H-beam height: 1.5 m, 1.8 m, and 2.0 m. Among them, the 2.0 m version is a mature standard configuration and is used here as the reference for a more detailed introduction.
