High-Strength Prestressed Concrete Steel Strand for Global Infrastructure Projects
Chunpeng Group, a globally recognized manufacturer with over three decades of expertise in prestressed concrete (PC) steel materials, delivers premium-quality PC steel strands engineered to meet the rigorous demands of modern construction. Our products are designed for durability, performance, and compliance with international standards such as GB/T5224-2014 and JIS3536, ensuring reliable structural integrity across diverse environments—from coastal regions to high-altitude terrains.
Our core offering includes ultra-high tensile strength PC strands, Normal Tensile Strength variants, unbonded systems, galvanized options for enhanced corrosion resistance, weather-resistant solutions, and precision-engineered PC Steel Wire. Each product type is tailored for specific engineering applications, providing engineers and contractors with flexible, future-ready material choices that support sustainable infrastructure development worldwide.
Key features include a nominal diameter of 28.6 mm, tolerance control within +0.40/-0.15 mm (GB standard) or +0.60/-0.25 mm (JIS), and a minimum breaking load of 990 kN at a tensile strength of 1860 MPa. With an elongation rate of 3.5% over a 500 mm gauge length and a relaxation value not exceeding 2.5% after 1000 hours under 70% of specified breaking load, our strands ensure long-term stability and reduced maintenance costs. The lay length ranges from 12 to 18 times the strand diameter, promoting optimal handling and installation efficiency while minimizing stress concentration during tensioning operations.
These high-performance Prestressed Steel strands are ideal for large-scale civil engineering projects including bridges, viaducts, high-rise buildings, precast elements, and railway structures. They provide superior load-bearing capacity, reduce cracking risks in concrete, and improve overall service life—making them indispensable in seismic zones, industrial facilities, and transportation networks where safety, longevity, and cost-efficiency are paramount.
Users across Europe, North America, Southeast Asia, and Oceania consistently praise the reliability of Chunpeng’s PC steel strands. Contractors report fewer field adjustments due to consistent dimensional accuracy and predictable mechanical behavior, while structural engineers appreciate the seamless integration with anchorage systems and photovoltaic mounting solutions offered by the same manufacturer—a rare advantage in integrated infrastructure supply chains.
Common inquiries often revolve around compatibility with different concrete grades, ease of splicing, and long-term performance in aggressive environments. We recommend using certified couplers for joint connections and applying protective coatings when exposed to chlorides or salt spray. Unlike some competitors who offer generic specifications, our products undergo strict quality checks aligned with ISO-certified production processes, guaranteeing uniformity batch-to-batch and project-to-project.
