--- Why Choose Our Prestressed Concrete Steel Strand? ---
• Unmatched Strength and Durability:
Tianjin Chunpeng Group’s prestressed concrete steel strands are engineered for extreme performance in demanding environments. Our ultra-high strength steel strands, with tensile strengths reaching up to 2360MPa, are rigorously tested and certified to international standards including GB/T5224, ASTM A416, EN10138, and ISO6934. These strands have been successfully deployed in landmark infrastructure projects such as the West Main Road Project of Xiongan Station, where retard-bonded and anti-corrosion steel strands were used to ensure long-term stability in harsh geological conditions. The Hangzhou-Haining Intercity Railway and the Guojiatuo Yangtze River Bridge also relied on our bonded and unbonded steel strands to withstand dynamic loads and environmental stressors. In coal mining applications, our mine-used anchor cable steel strands have proven their safety and reliability across major operations under China National Coal Group Corporation and Jinneng Holding Coal Group. With production bases strategically located in Tianjin, Chongqing, and Yunnan, we maintain consistent quality control across all facilities. Our proprietary acid-free pickling process not only reduces environmental impact by saving 64kg of purified water and fuel per ton of product but also enhances material integrity, ensuring superior fatigue resistance and corrosion protection. Whether supporting massive bridge spans or securing underground tunnels, Chunpeng’s steel strands deliver unmatched durability, making them the preferred choice for engineers and contractors worldwide.
--- Our Commitment to Quality and Safety ---
• ISO-Certified Manufacturing Processes:
At Tianjin Chunpeng Group, quality is not just a promise—it’s a system. We have achieved full certification across ISO9001 (Quality Management), ISO14001 (Environmental Management), OHSAS18001 (Occupational Health & Safety), and the Industrial and Information Integration System, reflecting our holistic approach to sustainable and safe manufacturing. Our state-of-the-art production lines, equipped with advanced automation and real-time monitoring systems, ensure precision at every stage—from raw material selection to final inspection. With 50 critical quality control checkpoints throughout the production cycle, we maintain a 100% product qualification rate. This rigorous oversight was instrumental in delivering steel strands for the CCTV New Headquarters Building, constructed by Baoding Yinyan, where structural integrity and dimensional accuracy were paramount. Additionally, our innovative non-coating process, implemented successfully in 2020, eliminates chemical waste while enhancing surface consistency and bond strength. The company’s chief engineer, a recipient of the State Council’s Special Allowance, leads a team of experts dedicated to continuous improvement. Our compliance with national and international standards—including CCPC Certification and DCMM Level 2—ensures traceability, data security, and operational excellence. Every strand we produce is more than a component; it’s a testament to our unwavering commitment to safety, sustainability, and technological leadership.
• 100% Product Quality Assurance:
Tianjin Chunpeng Group stands behind every product with a 100% quality assurance policy, rooted in decades of engineering excellence and customer trust. Our products are not only manufactured to meet but often exceed global benchmarks such as ASTM A416, EN10138, and AS/NZS4672. This commitment has been validated through real-world applications in high-profile projects like the Jinwei High-Speed Railway, where our high-tensile steel strands provided reliable reinforcement across critical bridge segments. Similarly, the Binzhou Yellow River Bridge, built by China Railway Major Bridge Engineering Group, utilized our anti-corrosion and weather-resistant steel strands to endure prolonged exposure to moisture and fluctuating temperatures. In the energy sector, our collaboration with National Energy Group and China Shenhua Energy Co., Ltd. has seen our mine-used anchor cables deployed in deep-seated tunneling operations, where failure is not an option. Our ability to customize solutions—from 1×3 configurations to custom diameters ranging from Φ6 to Φ32—ensures that each project receives tailored support. Furthermore, our PV bracket systems, including flexible and adjustable tilt types, have been tested in wind tunnel simulations at the China Academy of Aerospace Aerodynamics, proving resilience against typhoon-force winds up to level 16. With certifications such as ‘National High-Tech Enterprise’ and ‘Specialized, Refined, Peculiar and Innovative Enterprise,’ we are recognized not only for technical prowess but for delivering dependable, future-ready infrastructure materials. When you choose Chunpeng, you’re choosing peace of mind, performance, and proven results.
