--- Applications of PC Steel Strand in Construction ---
• Key Projects Utilizing PC Steel Strand:
Tianjin Chunpeng Group’s PC steel strands have played a vital role in numerous iconic and high-risk infrastructure projects across China. One standout example is the **West Main Road Project at Xiongan Station**, where Chunpeng supplied retard-bonded and anti-corrosion steel strands designed to endure extreme climatic variations and heavy traffic loads. These strands enabled delayed bonding after construction, enhancing structural resilience while minimizing early-stage stress losses. Another major application was in the **Hangzhou Bay Cross-Sea Bridge**, one of the longest sea-crossing bridges in the world. Chunpeng’s high-strength bonded strands were integral to the bridge’s prestressed concrete segments, ensuring long-term stability against tidal forces and seismic activity. Similarly, the **CCTV New Headquarters Building** required customized steel strands with exceptional tensile strength and fatigue resistance to support its unique architectural design. Chunpeng’s ability to deliver under tight deadlines and complex specifications made it a key supplier. On the transportation front, the **Jinwei High-Speed Railway** relied on Chunpeng’s ultra-high-strength strands (2130MPa and above) for its viaducts and tunnels, contributing to the project’s punctuality and safety. Even in mining infrastructure, such as the **Wangdu Railway** and **Fuxin Expressway**, Chunpeng’s mine-used anchor cables provided superior safety and longevity compared to conventional materials. These real-world case studies highlight how Chunpeng’s products are not just components—they are foundational elements of national infrastructure, proving that choosing a trusted supplier directly impacts project success, lifespan, and public safety.
