Product Description
The 3-strand stressing slab post-tensioning flat anchorage with matching wedges is a high-performance prestressing component engineered for medium-span thin-walled concrete structures. Ideal for small-to-medium bridges, floor slabs, and precast concrete panels, it securely locks 3 flat steel strands via a self-locking wedge mechanism. This system delivers stable prestress retention, effectively enhancing structural crack resistance and load-bearing capacity while fitting space-restricted installation environments.
Core Advantages
- Space-Optimized Flat Design: Ultra-compact flat profile perfectly suits narrow spaces in medium-span thin-walled components, eliminating the need for structural thickening and reducing overall project costs.
- Reliable 3-Strand Self-Locking Anchorage: Precision-machined wedge tooth profiles create a tight bite with steel strands, ensuring an anchorage efficiency coefficient ≥95%. No slippage occurs during long-term use, guaranteeing structural safety.
- Heavy-Duty & Corrosion-Resistant: Forged from premium 45# alloy structural steel and finished with hot-dip galvanizing or phosphatization, the product withstands over 1.8 million fatigue cycles and 500+ hours of salt spray corrosion, adapting to harsh construction environments.
- Quick & Hassle-Free Installation: Precisely sized to fit 15.24mm GB/ASTM standard flat steel strands, it achieves seamless alignment with anchor holes. On-site installation requires no additional adjustments, significantly boosting construction efficiency.
