Steel structure highway

1. Core Product Positioning

The Steel Structure Expressway is a modern elevated road system that utilizes high-performance steel as the core load-bearing material. Specifically designed for urban viaducts, overpasses, interchanges, mountain expressways, and long-span bridges, it employs modular prefabrication, intelligent assembly, and full lifecycle management to construct a transportation backbone network with exceptional load-bearing capacity, rapid deployment capability, and superior durability.

2. Core Product Advantages

1. Leading Whole-Lifecycle Construction & Economic Efficiency

• Rapid Construction: With over 90% factory prefabrication for the main structure, on-site work primarily involves high-strength bolting, reducing bridge erection time by 50%-70% compared to traditional cast-in-place concrete, thereby minimizing disruption to existing traffic.

• Optimized Comprehensive Cost: Its light weight reduces piling and foundation costs by approximately 30%; the shortened timeline saves significant management and financial expenses; high steel recovery value at future renovation or demolition ensures outstanding whole-lifecycle economics.

• Long-Span & Lightweight Design: Enables easy achievement of column-free spans exceeding 60 meters, reducing pier footprint and optimizing route alignment; the light structure weight benefits seismic resistance (up to 9-degree fortification) and minimizes ground treatment.

• High Quality & Extended Lifespan: Intelligent factory production ensures millimeter-level precision, eliminating common concrete defects like cracking; coupled with a multi-layer anti-corrosion system (e.g., hot-dip galvanizing + heavy-duty coating), the design life can exceed 100 years with long maintenance intervals and low costs.

• Environmentally Friendly Construction: Primarily dry construction methods reduce construction waste by over 80%, with minimal on-site noise and dust pollution.

• Adaptability to Complex Scenarios: Particularly suitable for challenging terrains such as crossing rivers, valleys, and existing traffic lines, as well as emergency projects or municipal upgrades requiring rapid construction and traffic maintenance.

3. Product Technical System & Future Expansion

1. Core Technical Systems: Mainly include bridge structures such as steel box girders, steel truss girders, and steel-concrete composite girders, along with modular steel deck paving systems.

2. Intelligent & Resilient Integration: Facilitates the integration of smart systems like structural health monitoring, vehicle-infrastructure cooperation communication, photovoltaic noise barriers, and snow-melting/de-icing, enabling the development of intelligent, resilient corridors.

3. Sustainable Development Value: Its rapid construction capability allows early realization of the socio-economic benefits of the road network; the industrialized construction model and recyclability perfectly align with national strategies for green infrastructure and the circular economy.
