--- Why Choose Chunpeng Steel Strands? ---
• High-Quality Manufacturing Standards:
Tianjin Chunpeng Group has been a leader in the production of prestressed concrete steel strands since its founding in 1994. With seven industrial bases across China—located in Tianjin, Chongqing, and Yunnan—the company leverages advanced technology and rigorous quality control to deliver superior products. Our manufacturing process includes the industry-leading acid-free pickling system, which reduces environmental impact by eliminating harmful chemicals while saving up to 64kg of purified water and fuel per ton of product. This innovation not only aligns with global sustainability goals but also ensures consistent product quality. We have achieved full compliance with ISO9001, ISO14001, OHSAS18001, and DCMM Level 2 certification, reflecting our commitment to excellence. The chief engineer at Chunpeng enjoys a State Council special allowance, underscoring our technical depth. Every product undergoes inspection at 50 critical process stages, guaranteeing a 100% qualification rate. Our steel strands comply with international standards including GB/T5224, ASTM A416, EN10138, and ISO6934, making them suitable for high-stakes infrastructure projects worldwide.
• Wide Range of Applications:
Chunpeng’s PC steel strands are engineered for diverse, demanding applications. For instance, our bonded prestressed concrete steel strands were instrumental in the construction of the Jinwei High-Speed Railway and the Binzhou Yellow River Bridge, where structural integrity under extreme loads was paramount. The West Main Road Project of Xiongan Station, managed by Beijing Urban Construction Group, utilized our retard-bonded and anti-corrosion steel strands to withstand harsh weather and long-term exposure. In mining operations, our mine-used anchor cable steel strands have been deployed in major coal mines across Shanxi and Heilongjiang, providing unmatched safety and stability. Beyond traditional infrastructure, Chunpeng’s flexible PV brackets have been successfully implemented in large-scale solar farms in arid regions of northwest China, where they resist sandstorms and provide durable support for photovoltaic panels. These systems have also been used in fishery-PV complementary projects, enabling dual-use of water surfaces for both aquaculture and clean energy generation. Whether it's supporting multi-storey industrial plants, stadium roofs, or geotechnical anchoring systems, Chunpeng’s products are trusted by national key enterprises such as China Railway Group Limited, China State Construction Engineering Corporation, and National Energy Group. With over 30 years of experience and a proven track record in complex projects, Chunpeng delivers reliable performance across industries.
