Product Description
Our AWS D1.5 Compliant Curved Steel Arch Bridge is a complete heavy-load long-span traffic bridge solution tailored for American standard infrastructure projects. All structural design, steel material selection, integral forming and welding construction strictly execute U.S. unified industry standards. Adopting modular workshop prefabrication mode and equipped with diversified high-strength steel options, this curved steel arch bridge delivers stable bearing capacity, long service life and full code compliance, widely adopted in urban viaducts, cross-river bridges and large landscape traffic engineering across North America.
Diversified ASTM A709 Steel Grades & Comprehensive Material Inspection Items
• Available steel grades: Grade 36, Grade 50, weather-resistant Grade 50W, high-performance HPS 50W and HPS 70W, yield strength ranges from 36 ksi to 100 ksi
• Weathering steel advantages: W-series steel forms a natural anti-rust protective patina in atmospheric environment, greatly reducing later maintenance and renovation costs
• Batch mandatory inspection: Raw material chemical composition heat analysis, tensile & yield strength mechanical test, Charpy V-notch low-temperature impact test
• Structural performance: Thickened high-strength steel main arch body adapts to heavy truck loads, ultra-long span layout and complex geological site conditions
Full-Set AWS D1.5 Certified Welding & Fracture Risk Control System
- • All main force-bearing welds of the whole arch bridge strictly abide by AASHTO/AWS D1.5M/D1.5:2025 Bridge Welding Code, recognized by U.S. DOT and professional design firms
- • Our factory holds valid AWS fabricator certification; all welding procedures and operating staff pass official qualification review and filing
- • Complete Fracture Control Plan is implemented for Fracture-Critical Members per AWS D1.5 Clause 12 to eliminate potential structural safety hazards
- • Full penetration butt welds and heavy fillet welds on main arch ribs receive 100% NDT nondestructive testing to remove internal welding defects
High-Precision Curved Arch Forming & Modular Prefabrication Merits
Supported by integrated CAD & CAM digital intelligent processing equipment, we realize precise customization of any curved arch radian with strict dimensional tolerances. The full-shop prefabrication mode brings multiple prominent advantages for global bridge construction projects:
- 1.Greatly reduce on-site welding workload and shorten overall construction erection cycle
- 2.Closed factory production avoids quality instability caused by outdoor wind, rain and temperature changes
- 3.Complete integral assembly and fitting inspection before delivery to ensure seamless splicing during field installation
- 4.Segmented separate shipment optimizes container loading plan and cuts cross-border logistics transportation expenses
