Product Positioning

Focused on complex urban viaducts and interchange bridges with wide decks, small-radius curves, and bifurcated sections, offering two cross-section configurations: single-box multi-cell and multi-box single-cell, suitable for bridge widths of 12–25 meters and spans of 40–120 meters.

Core Advantages

Closed-section cross-sections have extremely high torsional stiffness, so curved bridges require no additional torsional structures; construction can use the push-launching method or assembly on scaffolds, allowing it to span busy roads below without affecting existing traffic.

Global Compliance

Strictly meets mainstream international standards including European Standards (EN 1993-1-5 Plate Buckling and EN 1993-2 Steel Box Beam Distortion), American Standards (AASHTO LRFD Appendix B Orthotropic Plate Fatigue and AWS D1.5 Welding), and Australian Standards (AS 5100.4 Box Girder Flange Width-Thickness Ratio and AS 5100.6 Composite Deck).

Service Assurance

Provides full-cycle technical support from distortion buckling analysis, cross-frame spacing optimization, push-launching construction simulation, to orthotropic plate U-rib-to-deck weld fatigue verification and on-site circumferential welding solutions.
