Product Description
Heavy Steel Arch Bridge Engineered Fully to US AASHTO LRFD20 AISC303 & AWS D1.5 Welding Standards is a robust long-span steel arch structural solution developed for North American and cross-border highway, municipal and river-crossing bridge projects. Every link covering structural calculation, steel material selection, component fabrication and welding execution strictly complies with three mainstream US authoritative standards: AASHTO LRFD20 highway load design specification, AISC303 structural steel manufacturing code and AWS D1.5 bridge welding standard. All heavy load-bearing arch components are completely prefabricated in our standardized workshop with precise size control and multi-round quality inspection, presenting exceptional structural stiffness, outstanding spanning capability and long-term durability for heavy traffic and complex natural environments.
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.
High-Grade Heavy Structural Steel Materials
All primary force-bearing parts such as thick arch ribs and main curved girders adopt high-strength thick steel plates that satisfy US bridge material requirements. Complete mill test certificates are supplied for every batch of raw steel to verify mechanical performance and chemical composition. Thickened steel configuration greatly improves overall structural rigidity, adapting to heavy vehicle loads, ultra-long span construction and complicated geological site conditions.
Standardized Heavy Fabrication & Certified Welding Process
Massive steel components are processed via CNC precision cutting, heavy tonnage bending and fixed fixture assembly to maintain stable dimensional accuracy. Vital full penetration butt welds and heavy fillet welds are constructed under standardized AWS D1.5 operating procedures. All welders hold corresponding qualification certificates, and key welding joints undergo 100% NDT non-destructive testing to eliminate internal welding defects and secure long-term structural safety under heavy loads.
Complete Modular Prefabricated Arch Components Supply
We deliver a full set of matched heavy arch bridge structural accessories, including thick curved arch ribs, main arch girders, transverse bracing frames, stiffener plates and hot-dip galvanized bridge decking. More than 85% cutting, forming and welding work is finished in factory modules. Segmented separate delivery largely reduces field welding workload, shortens overall construction schedule and lowers outdoor construction risks for overseas construction teams.
Customized Structural Design Optimization Service
Our professional structural engineering team adjusts arch span, arch rise ratio, traffic load grade and bracing layout according to clients’ construction drawings and actual site geological conditions. We optimize heavy arch structure schemes to balance spanning demand, project budget and regional climate characteristics, while permanently keeping full compliance with AASHTO LRFD20, AISC303 and AWS D1.5 without sacrificing structural safety margin.
Multi-Layer Protective Anti-Corrosion Treatment
Two mature long-lasting anti-corrosion solutions are available for all heavy steel arch members: hot-dip galvanizing treatment or multi-layer heavy-duty bridge anti-rust paint coating. The dense protective layer isolates the steel substrate from rain, humid air and coastal salt spray erosion, extending the designed service life of this heavy steel arch bridge to over 50 years under normal traffic operation conditions.
