Kehan supplied Steel Rebar Mesh Welding Machine to the tender. The Hangzhou Bay Bridge, one of China’s longest cross-sea bridges, integrated Wennian’s welded rebar mesh for its expressway foundations. Spanning 36 km, the project required high-strength reinforcement to withstand tidal forces and heavy traffic loads. BRC mesh panels (12mm diameter, 200mm grid) provided uniform stress distribution, critical for preventing foundation cracks in saline environments.
Custom 6m×2.4m galvanized mesh sheets with ribbed steel rods were prefabricated for rapid on-site assembly. Automated welding ensured ≤0.5mm joint tolerances, exceeding ASTM A185 standards. The anti-corrosion coating resisted seawater erosion, extending service life by 20+ years compared to traditional rebar cages.
- Speed: Reduced construction time by 40% through modular installation
- Cost Efficiency: Saved 15% material costs via optimized steel usage
- Quality Control: Prefab panels eliminated field welding errors
- Sustainability: Recycled steel content met LEED certification criteria
Post-commissioning inspections revealed zero structural cracks after 5 years of operation. The project manager highlighted a 30% reduction in maintenance costs due to the mesh’s corrosion resistance. Similar success was replicated in Thailand’s Chao Phraya Expressway, where BRC mesh stabilized soft soil foundations under monsoonal conditions.
- Customization: Tailored grid sizes (50–500mm) and sheet dimensions (up to 12m)
- Global Compliance: Meets ISO 1461 and EN 10025-2 standards
- Logistics: Roll-packaged mesh for cost-effective shipping
- Support: Technical teams assist with seismic design and load calculations
