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.

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.

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).

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.

Product Positioning:Specially designed steel pile products for deep bridge foundations, hydraulic cofferdams, and bridge piers in high seismic zones, providing high load-bearing capacity and impact resistance. The range includes H-shaped steel piles, open and closed steel pipe piles, suitable for permanent or temporary support structures.

Core Advantages:High bending stiffness and excellent hammering toughness, capable of meeting ultra-long designed pile lengths through on-site splicing; fast construction speed, low soil displacement rate, no concrete curing waiting period, and temporary piles can be fully recovered and reused.

Global Compliance:Strictly meets mainstream international standards including European standards (EN 1997 geotechnical design and EN 10248 steel sheet piles), American standards (ASTM A572/A690 pile materials and AASHTO LRFD Chapter 10 Foundations), and Australian standards (AS 2159 pile foundation design and construction and AS 5100 bridge foundations).

Service Guarantee:Provides full-process technical support from geotechnical parameter verification, pile drivability analysis (WEAP wave dynamics simulation), pile type optimization, welding process evaluation to on-site high-strain dynamic monitoring and static load testing.
