--- Why Choose Our PC Steel Strand? ---
• Superior Strength and Durability:
Tianjin Chunpeng Group’s PC Steel Strand stands out in the global market due to its unmatched tensile strength and long-term durability. With ultra-high strength grades reaching up to 2360MPa, our bonded prestressed concrete steel strands are specifically designed for high-stress environments such as long-span bridges, high-rise buildings, and underground infrastructure. The company’s proprietary acid-free pickling process—implemented across all production bases since 2021—ensures zero chemical pollution while significantly improving material integrity and reducing resource consumption by up to 64kg of purified water and fuel per ton of product. This advanced manufacturing technique not only enhances environmental sustainability but also guarantees consistent microstructure and surface quality. Furthermore, our steel strands undergo rigorous testing at 50 critical process stages, achieving a 100% product qualification rate. The result? A product that performs reliably under extreme conditions—whether it’s the relentless vibrations of metro lines or the harsh weather of desert regions. For instance, during the construction of the Hangzhou Bay Cross-Sea Bridge, Chunpeng’s steel strands were used in post-tensioned segments, successfully withstanding typhoon-force winds and saltwater corrosion, proving their resilience in one of China’s most demanding marine engineering projects.
• Compliance with International Standards:
At Tianjin Chunpeng Group, compliance is not just a policy—it’s a promise. Our PC Steel Strands meet and exceed multiple international standards, including GB/T5224 (China), ASTM A416 (USA), EN10138 (Europe), ISO6934 (International), and JIS G3536 (Japan). These certifications ensure seamless integration into global construction projects, regardless of location or regulatory framework. For example, when constructing the CCTV New Headquarters Building, the project team selected Chunpeng’s anti-corrosion and weather-resistant steel strands due to their proven performance under prolonged exposure to urban pollutants and fluctuating temperatures. Similarly, the West Main Road Project of Xiongan Station utilized our retard-bonded steel strands, which were tested and approved under JG/T369 standards, enabling delayed bonding after structural curing to optimize stress transfer. Our products have also been certified with CCPC and DCMM Level 2, reflecting our leadership in data-driven quality control and digital transformation. With full traceability from raw material sourcing to final delivery, customers can trust that every batch of steel strand is rigorously verified. This level of standardization has earned us recognition as a National High-Tech Enterprise and a Specialized, Refined, Peculiar, and Innovative (‘Zhuanjing Qiyou’) enterprise—testaments to our technical excellence and industry leadership.
--- Applications of PC Steel Strand ---
• Ideal for Construction Projects:
Tianjin Chunpeng Group’s PC Steel Strands are the backbone of modern infrastructure, delivering precision and reliability in complex construction scenarios. From high-speed rail systems to urban transit networks, our strands are integral to projects requiring high load-bearing capacity and long-term stability. Take the Jinwei High-Speed Railway, currently under development: Chunpeng supplied over 12,000 tons of 2130MPa bonded steel strands for pre-stressed beams, ensuring structural integrity across hundreds of kilometers of track. The strands’ ability to resist creep and relaxation under sustained loads made them ideal for this high-speed application. In another landmark case, the Changchun Metro Line 9 project relied on our unbonded steel strands for tunnel linings and station platforms, where flexibility and corrosion resistance were critical. The use of grease-coated, plastic-jacketed strands allowed for smooth tensioning and reduced maintenance needs in humid underground tunnels. Even in architectural marvels like the Binzhou Yellow River Bridge, our steel strands were used in post-tensioned box girders, supporting spans exceeding 100 meters. The bridge’s designers praised the consistency and uniformity of the strands, which contributed to minimal deflection and enhanced safety margins. Whether it’s a single beam or an entire bridge system, Chunpeng’s PC Steel Strands are engineered to deliver optimal performance, reduce lifecycle costs, and support sustainable construction practices.
• Versatile Use in Mining and Infrastructure:
Beyond civil engineering, Chunpeng’s steel strands are indispensable in mining and geotechnical applications, where safety and reliability are non-negotiable. The company’s mine-used anchor cable steel strands have been deployed in major coal mines across Shanxi, Inner Mongolia, and Heilongjiang, including operations under Jinneng Holding Coal Group and China National Coal Group Corporation. These strands, often rated at 2230MPa, are used in roadway support systems to prevent roof collapses in deep-seam mining. For example, at the Fuxin Expressway project, Chunpeng’s anti-corrosion steel strands were installed in steep slope stabilization works, resisting both moisture and mechanical wear in unstable terrain. The strands’ galvanized coating and protective sheathing ensured longevity in harsh, acidic soil conditions. Additionally, our flexible PV brackets—made using high-strength steel strands—have been integrated into solar farms in arid regions like Xinjiang and Ningxia, where wind resistance and lightweight design are crucial. One notable installation was the Yunnan Chunpeng Solar Farm, where flexible bracket systems supported 500kW of photovoltaic panels across a 20-acre wasteland. The system passed a wind tunnel test conducted by the China Academy of Aerospace Aerodynamics, demonstrating resistance to Category 16 typhoons. This versatility underscores Chunpeng’s ability to innovate beyond traditional steel strand applications, offering solutions that combine structural integrity with renewable energy advancement.
--- Quality Assurance and Certifications ---
• ISO9001 and Environmental Management:
Tianjin Chunpeng Group’s commitment to quality and sustainability is backed by a robust management system certified under ISO9001, ISO14001, and OHSAS18001. These certifications reflect our holistic approach to operational excellence—from product development to environmental stewardship. Our ISO9001 certification ensures that every phase of production, from raw material inspection to final packaging, adheres to strict quality protocols. The chief engineer, who enjoys a State Council Special Allowance, leads a dedicated team that conducts 50-point quality checks, including tensile testing, elongation measurement, and surface defect analysis. This meticulous oversight results in a 100% qualification rate, a benchmark few manufacturers can match. Simultaneously, our ISO14001 certification underscores our green manufacturing philosophy. Since 2020, Chunpeng has fully transitioned to an acid-free pickling process, eliminating hazardous waste and reducing water usage by over 40%. This innovation aligns with national carbon neutrality goals and has positioned us as a leader in eco-friendly steel production. We’ve also achieved DCMM Level 2 certification, validating our data management capabilities and enabling real-time monitoring of production metrics. These systems allow us to predict potential defects before they occur, further enhancing product consistency. As a result, clients like China Railway Group Limited and Sichuan Shudao Group trust Chunpeng not only for product quality but also for responsible industrial practices. Our dual focus on performance and sustainability makes us a preferred supplier for large-scale public infrastructure and green energy projects worldwide.
