Product Positioning

Focused on medium-to-large steel arch bridges spanning deep valleys, navigable waterways, and urban landscape nodes, offering three structural systems: deck arch, through arch, and tied arch, suitable for different foundation conditions and clearance requirements.

Core Advantages

The combination of arch rib compression and high-strength steel properties enables long-span capabilities (60–200 meters) without piers below the bridge; using balanced cantilever or segmental erection construction, it can cross existing railways/highways without interrupting operations below.

Global Compliance

Strictly meets mainstream international standards including European standards (EN 1993-2 arch bridge stability and EN 1991-2 traffic loads), American standards (AASHTO LRFD in-plane/out-of-plane arch rib buckling and AWS D1.5 welding), and Australian standards (AS 5100.4 steel arch rules and AS 5100.7 hanger fatigue).

Service Guarantee

Provides full-cycle technical support from arch axis optimization (compression line fitting), nonlinear stability analysis (geometric and material nonlinearities), hanger tension sequence simulation, to balanced cantilever construction counterweight design and wind tunnel testing (if necessary).

As a classic structural bridge type, the steel arched bridge features high-strength steel components and an optimized arch structure, which delivers exceptional load-bearing performance, long service life and elegant appearance. It is widely applied in various traffic and landscape projects, serving as both a reliable transportation link and an eye-catching architectural landmark.

Steel arch bridge adopts curved steel arch stress structure, with outstanding large-span bearing performance, elegant overall shape and reliable structural safety. It is widely used in river crossing, urban landscape, mountain valley traffic engineering, integrating engineering durability, traffic practicality and architectural artistic beauty.

The steel arched bridge is a iconic civil engineering structure that combines high-strength steel with a scientific arch design. It boasts excellent load-bearing capacity, long-span performance and corrosion resistance, integrating practical transportation functions with unique architectural aesthetics, and becoming a vital link and landscape landmark in various scenarios.

Product Positioning:Specializing in medium-to-large steel arch bridges that span deep valleys, navigable waterways, and key urban landscape nodes, offering three structural types: deck arch, through arch, and tied arch, adaptable to different foundation conditions and clearance requirements.

Core Advantages:The combination of compressive arch ribs and high-strength steel properties enables long spans (60–200 meters) with no piers underneath; rotational or cantilever erection methods allow crossing existing railways or roads without interrupting operations below.
