We provide turnkey solutions from concept to maintenance, meeting technical and code requirements of global markets:
We specialize in the design, fabrication, and installation of prefabricated steel highway bridges, providing high-strength, highly durable, and rapid-construction solutions for crossing rivers, gorges, roads, and obstacles on global highways, railways, and heavy haul routes. Our all-steel bridges employ modular design, suitable for new construction, replacement, and emergency repair projects, serving as a modern, efficient alternative to traditional concrete bridges.
Features & Core Advantages
Rapid Construction, Minimized Traffic Disruption
Major components are highly prefabricated in the factory, requiring only rapid lifting and bolting on-site, reducing construction time by 50%-70% compared to cast-in-place concrete. Ideal for bridge replacement on busy routes and post-disaster emergency projects.
Superior Economy & Lifecycle Value
Lightweight steel reduces demands and costs for foundations and substructures. Excellent durability, maintainability, and modular replaceability result in lower total lifecycle cost than conventional bridges.
Outstanding Structural Performance & Design Flexibility
Steel's high strength-to-weight ratio makes it ideal for long spans and heavy loads. Flexible design accommodates curves, variable sections, and complex geometries for diverse aesthetic and functional needs.
Superior Sustainability & Environmental Friendliness
Steel is 100% recyclable. On-site work requires no formwork, no curing, and minimal wet work, drastically reducing noise, dust, and waste. Factory precision minimizes material waste, making it a truly green solution.
Safe, Reliable, and Quality-Controlled
All components are produced in a controlled factory environment with strict NDT (UT, RT) and quality management (ISO 3834, EN 1090), ensuring superior, consistent quality and long-term safety over on-site construction.
Our Customization & Service Scope
We provide turnkey solutions from concept to maintenance, meeting technical and code requirements of global markets:
Feasibility Study & Conceptual Design
Provide multiple concept comparisons (structure type, materials, construction method) and lifecycle cost analysis based on site surveys, geotechnical reports, and functional needs.
Detailed Design & Calculation Certification
Perform detailed structural analysis and simulation using MIDAS/STAAD, delivering full calculation reports and drawings compliant with AASHTO, Eurocode, or client standards. Assist with third-party review and authority approvals.
Specialized Design & Fabrication
Special Bridges: Steel girders/towers for cable-stayed/arch bridges, movable bridge mechanisms, and weathering steel (unpainted) bridge design.
Special Treatments: Fatigue-resistant detailing, coating systems for marine/de-icing salt environments, and integration of seismic/isolation devices.
Global Logistics & Site Support
Provide modular shipping plans to optimize costs and risks. Dispatch senior welding/erection engineers for site guidance, bolt torque control, and critical process inspection.
