Product Description
This shop-fabricated Weather-Resistant AASHTO LRFD Steel Arch Bridge suits highway crossings demanding long service life and low upkeep. Built from ASTM A709 Grade 50W weathering steel, it creates a natural protective patina under atmospheric exposure without repeated painting. Designed to AASHTO LRFD and fabricated following AWS D1.5M, the closed-box arch system offers reliable spanning performance. Modular bolted assembly minimizes site work and satisfies North American engineering requirements.
Weathering Steel Advantages
• Forms dense self-protecting patina to resist corrosion- • Eliminates initial painting and periodic repainting, lowering lifecycle costs
- • Eco-friendly with no VOC emissions from coatings
- • Distinct natural brown appearance that harmonizes with surroundings
- • Proven 50+ years of successful global bridge applications
AASHTO LRFD Compliance
• Adopts LRFD design philosophy; all critical limit states verified- • Supports HL-93 highway live load
- • Steel design follows AASHTO LRFD Section 6
- • Material conforms to AASHTO M270
- • Compliant with AASHTO seismic requirements
- • 75 – 100+ years design life
AWS D1.5M Welding Standards
• Welding specifications optimized for weathering steel- • 100% UT inspection on all fracture-critical load-bearing welds
- • Work completed by AWS-certified welders under CWI supervision
- • Supplementary MT/PT testing implemented as required
