Heavy Duty Welded Bent Metal Low Carbon Structure Transportation Project Steel Bridge
Key Features
50-Year Lifespan & Long-Term Durability
High-quality structural steel (Q355q, Q420q, EN S355/S420 series) with excellent toughness and anti-fatigue performance. Professional anti-corrosion treatment (hot-dip galvanizing + epoxy zinc-rich primer + fluorocarbon topcoat) per ISO 12944 standards, ensuring 50-year service life.
121+ Mph Wind Resistance
Optimized modular truss structure with triangular framework design effectively distributes wind load. Wind resistance reaches 121+ Mph (195+ km/h), meeting requirements for hurricane-prone areas with 1.2x safety factor.
Modern Design & Modular Prefabrication
Modern minimalist design with sleek appearance. Modular prefabrication enables factory standardized production (error ≤±1mm) and reduces construction period by 40%-60% compared to traditional methods.
High Efficiency & Cost-Saving
Modular design allows flexible combination and expansion, reducing material waste and transportation costs. Lightweight structure minimizes foundation investment and saves labor costs.
Core Technology
  • Modular Truss Structure Technology: Triangular truss framework evenly distributes tensile and compressive forces, suitable for spans up to 91 meters with standardized interfaces for seamless assembly.
  • Precision Prefabrication & Welding Technology: Advanced CNC equipment with welding compliant to EN ISO 15614 and AWS D1.5 standards. 100% welding qualification rate with component precision meeting EN 10210/EN 10219 standards.
  • Anti-Corrosion & Durability Enhancement: Three-layer anti-corrosion system (hot-dip galvanizing + epoxy zinc-rich primer + fluorocarbon topcoat) with ≥80μm galvanizing layer and Z-direction performance steel.
  • Wind Resistance Optimization: Streamline truss section and aerodynamic diversion device reduce wind resistance and vortex-induced vibration, ensuring safe operation under extreme conditions.

Manufacturing Process
  1. Processing follows international standards (AISC 360, Eurocode 3, EN 1090) ensuring structural stability
  2. Strict raw material inspection including material certificate verification, size measurement and appearance inspection
  3. Lofting, marking and cutting performed by numerical control equipment for precise dimensions
  4. Straightening and correction (thermal or mechanical) to ensure component flatness
  5. Drilling and punching processes to meet assembly requirements
  6. Professional welding (submerged arc welding, gas shielded welding) with UT/MT non-destructive testing
  7. Secondary straightening and grinding to correct deformation and remove burrs
  8. Shot blasting to Sa2.5 derusting grade for enhanced coating adhesion
  9. Clear component marking, proper packaging and factory delivery
