Product Description
Precision Fabricated Steel Arch Bridge is a heavy-load modular bridge structure independently manufactured in our factory. The whole production chain from raw material procurement, digital forming, professional welding to surface anti-corrosion strictly enforces American authoritative industry codes including AASHTO LRFD20, AWS D1.5 and ASTM A709. Adopting segmented curved arch rib modular design and full off-site prefabrication, this steel arch structure delivers superior integral rigidity, remarkable long-span performance and stable load-bearing capacity. It has become a mainstream structural choice for urban viaducts, river-crossing traffic bridges and scenic landscape bridge projects across all global regions.

Core Material Standard
All primary load-bearing components are manufactured with ASTM A709 high-strength structural steel plate, featuring stable tensile strength, excellent toughness and fatigue resistance to adapt to long-term vehicle and natural environmental loads. Every batch of steel is accompanied by complete official mill test certificates, traceable material reports and chemical composition inspection documents, fully satisfying material acceptance criteria of North American bridge engineering projects and eliminating material quality risks for overseas owners.
Professional Fabrication & Welding Technology
Key components including arch ribs, curved I-girders and bridge deck panels undergo digital CNC cutting, precise cold bending and standardized workshop assembly to guarantee consistent dimensional accuracy. All load-critical welds are constructed in strict accordance with AWS D1.5 welding specification; full penetration butt joints and heavy fillet welds are 100% inspected via NDT non-destructive testing (UT/MT). Strict welding quality control eliminates internal defects, fundamentally securing long-term structural safety of the whole arch bridge.

AASHTO LRFD20 Compliance Design System
Our structural design team completes force calculation, live/dead load layout, seismic reinforcement and connection detailing fully following AASHTO LRFD20 highway bridge design specifications. Customized technical adjustment is available on demand: adjustable arch span, arch rise ratio, traffic load grade and lateral bracing layout based on clients’ construction drawings, site geological conditions and local infrastructure codes to achieve fully personalized AASHTO-standard arch bridge schemes.
Complete Prefabricated Component Supply
We provide one-stop full-set structural component supply for steel arch bridge projects, covering curved arch ribs, arch supporting girders, transverse cross bracings, secondary I-shaped beams and hot-dip galvanized bridge decking. Segmented prefabrication finishes over 85% of processing work inside the factory, drastically shortening on-site installation cycles, lowering field labor costs and minimizing weather-related construction delays for overseas engineering teams.

Anti-Corrosion Surface Treatment Option
Two mature anti-corrosion solutions are provided for all steel members: hot-dip galvanizing or high-performance multi-layer bridge anti-rust paint system. The dense protective layer effectively resists rain erosion, humid climate and coastal salt spray corrosion, stably extending the design service life of the entire steel arch bridge to more than 50 years under normal traffic operation environments.
Global Project Customization Service
Full customization support for international cross-border infrastructure projects, including adjustable overall dimensions, vehicle load grades, exterior decorative styles and supporting connection accessories. We can supply complete technical document packages required by foreign design institutes and general contractors, such as certified construction drawings, material inspection reports, welding NDT records and full standard certification files to accelerate local project approval progress.
