Bridges & Traffic Engineering
Prefabricated steel bridges are modular infrastructure systems designed for rapid construction and reliable load performance. These bridge systems are widely used in highway networks, railway crossings, pedestrian bridges, and urban overpass projects where construction speed and structural stability are critical requirements.
Compared with conventional cast-in-place bridges, prefabricated steel bridge systems significantly reduce on-site construction complexity through factory manufacturing and modular assembly methods.
Span range: typically 10–100+ meters depending on structural type
Design load standard: highway load models such as HL-93 or equivalent regional codes
Deflection control: generally limited to L/800–L/1000 span ratio
Wind load resistance: approximately 0.5–2.0 kN/m² depending on location and elevation
Seismic design level: suitable for moderate to high seismic zones
Service life: typically 50–75+ years with proper corrosion protection systems
As a prefabricated steel bridge solution provider, we deliver integrated engineering, manufacturing, and construction support for infrastructure projects ranging from highway crossings to large-span bridge systems.
We provide full-cycle engineering design support based on project requirements and international bridge standards:
Structural system design for plate girder, truss, box girder, and modular bridge systems
Load analysis based on highway traffic models such as HL-93 or equivalent standards
Span optimization from 10 meters to over 100 meters depending on project conditions
Wind, seismic, and fatigue performance calculation for long-term structural safety
BIM-based design coordination for multi-discipline integration
CNC cutting, drilling, and automated welding of steel components
Factory prefabrication rate up to 80%–95% depending on bridge type
Modular segment assembly and trial fitting before shipment
Anti-corrosion systems including galvanizing and multi-layer protective coatings
Strict dimensional tolerance control for on-site assembly accuracy
We provide engineering support during on-site bridge installation:
Modular installation planning and erection sequence optimization
High-strength bolted connection or welded joint assembly systems
Rapid installation methods reducing construction time by 30%–70%
Traffic interruption minimization strategies for urban and highway projects
Technical guidance for lifting, alignment, and final structural adjustment
We support full project execution from design to delivery:
Integrated design–manufacturing–installation coordination
Logistics planning for large steel bridge components
On-site technical supervision and installation support
Quality inspection and structural verification before handover
Compliance with international bridge engineering standards
