Product Positioning:Specially designed for new bridge construction and old bridge renovation projects, providing steel bridge decks that can be quickly installed. The range includes orthotropic steel decks (long lifespan), steel-concrete composite decks (high stiffness), and temporary steel grating decks (recyclable), suitable for different traffic volumes and construction schedules.

Core Advantages:Using closed U-ribs and high-strength steel top plates, fatigue resistance is improved by 50% compared to traditional open ribs; the waterproof layer and paving are pre-installed in the factory, allowing the bridge deck system to be completed immediately on site.

Global Compliance:Strictly compliant with mainstream international standards including European standards (EN 1993-1-5 local buckling of orthotropic decks and EN 1991-2 wheel load distribution), American standards (AASHTO LRFD Appendix B fatigue details and AWS D1.5 U-rib to top plate welds), and Australian standards (AS 5100.6 composite decks and AS 4100 thin plate stability).

Service Assurance:Provides full-cycle technical support, from fatigue grade verification of U-rib to top plate welds, analysis of collaborative deformation between paving layer and steel plate, integrated design of expansion joint slots, to on-site welding procedure evaluation and nondestructive testing solutions.

Our Steel Truss Bridge adopts high-strength hot-dip galvanized steel truss system, professionally designed for highway, pedestrian, railway and municipal crossing engineering. It integrates excellent load-bearing performance, lightweight structure and fast construction, perfectly adapts to river crossing, valley spanning, urban interchange and traffic reconstruction projects. The optimized open truss structure realizes reasonable stress distribution, matches diversified span layout, and maintains stable structural safety under complex natural environments.

Product Positioning:Focused on small- and medium-span (20–50 meters) highway bridges, railway bridges, and pedestrian bridges, offering welded I-girder sections, supporting both non-composite and composite deck configurations, compatible with prefabricated concrete slabs or cast-in-place decks.

Core Advantages:Utilizes web openings or corrugated webs to reduce steel consumption, variable-height beams to optimize material distribution; shear stud groups in combination with prefabricated concrete slabs shorten on-site construction time to one-third of conventional methods.

Global Compliance:Strictly complies with major international standards, including European standards (EN 1993-1-5 for post-buckling strength of plates and EN 1994 for composite beam shear connections), American standards (AASHTO LRFD for flange width-to-thickness ratio of composite beams and AWS D1.5 for fillet welds), and Australian standards (AS 5100.4 for I-girder web height-to-thickness ratio and AS 1554 for welding).

Service Guarantee:Provides full-cycle technical support, from optimizing the spacing of web stiffeners, verifying the slip of composite beam shear connectors, checking steel beam stability during construction (prior to concrete hardening), to designing on-site splicing joints and managing fatigue details.

Our Box Girder Steel Bridge delivers exceptional structural rigidity, long-term durability, and low-maintenance performance for permanent highway, railway, and urban crossings. Engineered for heavy loads and long spans, it is the ideal choice for high-traffic routes and challenging environments.

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.

Product Positioning:Focused on steel truss bridges for heavy-duty railways, mining area passages, and long-span highway bridges, offering Warren, Pratt, and Double-diagonal truss configurations. Suitable for spans ranging from 30 to 150 meters, supporting both welded connections and fully bolted connections.

Core Advantages:Members are primarily subjected to axial forces, resulting in high material efficiency; employing segmental prefabrication, overall lifting, or cantilever assembly methods, no support is needed under the bridge, allowing it to cross deep valleys and existing lines without interrupting operations.

Global Compliance:Strictly meets mainstream international standards including European standards (EN 1993-1-8 node plate buckling and EN 1993-2 truss fatigue), American standards (AASHTO LRFD truss slenderness limit and AWS D1.5 welding), and Australian standards (AS 5100.4 truss members and AS 4100 compression member stability).

Service Assurance:Provides full-cycle technical support from node plate Whitmore section verification, member slenderness optimization, fatigue detail classification control to pre-assembly schemes and segmented transportation design.

Product Positioning:Focused on urban elevated highways and interchange bridges with complex alignments such as wide bridge decks, small-radius curves, and branching sections, offering two cross-section configurations: single-box multi-cell and multi-box single-cell, suitable for bridge widths of 12–25 meters and spans of 40–120 meters.

Core Advantages:Closed-section cross-sections have extremely high torsional stiffness, so curved bridges require no additional torsional structures; construction can use the push-launching method or assembly on scaffolds, allowing it to span busy roads below without affecting existing traffic operations.

Global Compliance:Strictly meets major international standards, including European standards (EN 1993-1-5 thin plate buckling and EN 1993-2 steel box girder distortion), American standards (AASHTO LRFD Appendix B orthotropic plate fatigue and AWS D1.5 welding), and Australian standards (AS 5100.4 box girder flange width-thickness ratio and AS 5100.6 composite deck).

Service Guarantee:Provides full-cycle technical support from distortion buckling analysis, diaphragms spacing optimization, push-launching construction simulation, to orthotropic plate U-rib-to-deck weld fatigue checks and on-site circumferential weld solutions.

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.

Global Compliance:Strictly compliant with major international standards, including European standards (EN 1993-2 arch 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 regulations and AS 5100.7 hanger fatigue).

Service Guarantee:Provides full-cycle technical support, from optimizing arch axis lines (pressure line fitting), nonlinear stability analysis (geometric and material nonlinearities), hanger tension sequence simulation, to counterweight design for rotational construction and wind tunnel testing (if necessary).
