Product Positioning

Focused on small- and medium-span (20–50 meters) highway bridges, railway bridges, and pedestrian overpasses, providing welded I-girder sections, supporting both non-composite and composite deck modes, compatible with precast concrete slabs or cast-in-place decks.

Core Advantages

Using web openings or corrugated webs to reduce steel usage, variable-height beams to optimize material distribution; the combination of shear stud groups and precast concrete slabs shortens on-site construction time to one-third of traditional solutions.

Global Compliance

Strictly meets mainstream international standards such as 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 mixed-beam flange width-to-thickness ratio 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 Assurance

Provides full-cycle technical support from web stiffener spacing optimization, composite beam shear connector slip checks, steel beam stability verification during the construction phase (before concrete hardening), to on-site joint design and fatigue detail management.

Product Positioning

Focused on complex urban viaducts and interchange bridges with wide decks, small-radius curves, and bifurcated 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.

Global Compliance

Strictly meets mainstream international standards including European Standards (EN 1993-1-5 Plate Buckling and EN 1993-2 Steel Box Beam 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 Assurance

Product Positioning

Focused on steel truss bridges for heavy-duty railways, mining passages, and long-span highway bridges, offering three types of web member arrangements: Warren, Pratt, and Double Diagonal, suitable for spans ranging from 30–150 meters, supporting both welded joints and fully bolted connections.

Core Advantages

Members mainly bear 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).

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).

Product Positioning

Specifically designed to provide high-load-bearing, corrosion-resistant steel pile products for deep bridge foundations, high seismic zones, and marine environments. It covers three main series: open-ended steel pipe piles (soil plug effect), closed-ended steel pipe piles (end bearing), and H-shaped steel piles (penetrating hard layers).

Core Advantages

Uses double-wall isolation layer anti-corrosion (outer pipe, inner pipe, interlayer grouting) or sacrificial anode cathodic protection, with a design life of up to 100 years; construction employs hydraulic static pile driving machines, with noise below 65dB, suitable for urban areas and nighttime operations.

Global Compliance

Strictly meets mainstream international standards such as European standards (EN 1997-1 for pile foundation design and EN 1993-5 for steel pile corrosion allowance), American standards (ASTM A572/A690 for pile materials and AASHTO LRFD Chapter 10 for pile group efficiency reduction), and Australian standards (AS 2159 for pile drivability analysis and AS 5100.3 for negative skin friction calculation).

Service Guarantee

Provides full-cycle technical support from pre-analysis of pile drivability using wave equation (WEAP), calculation of pile group efficiency factors, design of sacrificial anode cathodic protection life, to high-strain dynamic measurement signal matching (CAPWAP) and static load test schemes.

Product Positioning

Specializing in lightweight scenic pedestrian bridges that span streams, ravines, and urban greenways, offering three structural forms: truss, slab, and arch bridges, suitable for deck widths of 1.5–3.0 meters and spans of 6–40 meters.

Core Advantages

Utilizes prefabricated concrete-steel composite decks to reduce live load vibration; railings integrate LED linear lighting and an emergency broadcast system, with a wet-state deck friction coefficient ≥0.7.

Global Compliance

Strictly meets mainstream standards including European norms (EN 1990-2 for pedestrian comfort and EN 1993-2 for steel bridge fatigue), American standards (AASHTO LRFD Section 3 for pedestrian loads and ADA Accessibility Guidelines), and Australian standards (AS 5100.2 pedestrian live load factor and DDA accessibility standards).

Premium welded steel plate girder bridge, featured with reasonable stress distribution, convenient construction and long service life, widely applied in municipal roads, highway crossings and small & medium span bridge projects.

Product Positioning

Focused on enclosed or open pedestrian corridors connecting two buildings, spanning city roads or scenic water bodies, offering two options: detachable modules and on-site welding, suitable for both indoor constant temperature and outdoor extreme cold environments.

Core Advantages

Universal sliding bearings are installed at both ends of the corridor to absorb independent settlements of the two buildings and seismic movements in different phases; the bridge deck uses hollow laminated glass with an anti-slip coating, providing both light transmittance and slip resistance.

High-strength integrated steel plate girder bridge, optimized stress structure, convenient prefabricated construction, strong weather resistance and long-term stable operation for highway and municipal traffic infrastructure.

Our steel plate girder bridge is a hot-rolled & welded steel girder structure specially developed for highway railway crossing engineering. It integrates large-span bearing capacity, stable structural performance and fast construction efficiency, fully adapts to complex river valley, mountain road and urban traffic bridge projects, meets international mainstream design specifications, and provides safe and durable long-span bridge solutions worldwide.

Product Positioning:Designed specifically for cast-in-place bridge decks and bridge deck maintenance projects, providing reusable or permanent steel formwork systems.
