Product introduction

 

Our comprehensive service integrates design R&D, production manufacturing, and on-site installation. We follow rigorous bridge design principles, applying Finite Element Analysis (FEA) and adhering to JTG D64-2015 standards. We utilize high-grade Q345 and Q420 bridge structural steel, processed on our advanced production lines, including steel plate pretreatment , CNC laser cutting , and U-Rib gantry welders. All critical components are welded by IGM intelligent robotic workstations  to ensure perfect alignment and structural integrity for both arch and truss elements.

 

Applications

 

  • Cross-River & Canal Steel Bridges
  • Heavy-Duty Steel Arch Bridges
  • Long-Span Steel Truss Bridges
  • Highway & Railway Waterway Crossings
  • Composite Arch-Truss Structures
  • Bridge Steel Structure
  • Steel Girder Systems for Highway Viaducts
  • High Volume Highway Bridge Manufacturing
