High-Strength Low-Relaxation Prestressed Concrete Strand – Engineered for Modern Infrastructure Excellence
Engineered with precision and built for durability, this high-tensile prestressed concrete strand is a cornerstone in modern civil engineering projects worldwide. Comprising seven high-strength steel wires twisted into a helical configuration, it delivers superior performance in tension-critical applications such as bridges, highways, railway systems, and large-span structures. Designed to meet international standards like EN10138-3:2011, this product exemplifies innovation in sustainable construction materials by reducing steel consumption by up to 30% while enhancing structural integrity.
Key features include exceptional tensile strength (1860 MPa), low relaxation properties that ensure long-term stability under load, and a nominal diameter of 9.3 mm—ideal for efficient anchoring and stress transfer. The strand’s cross-sectional area of 52.0 mm² and mass per meter of approximately 406 g/m make it both lightweight and highly effective in minimizing material waste without compromising safety margins. With characteristic values for maximum force (96.7 kN) and proof force at 0.1% strain (83.2 kN), it provides reliable performance across diverse environmental conditions.
This product stands out not only for its mechanical superiority but also for its eco-conscious design. As part of the global shift toward green building practices, this Prestressed Steel strand contributes to carbon reduction efforts—making it an ideal choice for environmentally responsible infrastructure development. Whether used in nuclear power facilities, hydropower plants, or urban skyscrapers, its ability to maintain consistent tension over time ensures longevity and reduces maintenance costs significantly.
Commonly referred to as "prestressing wire," "high-strength PC Strand," or "low-relaxation tendon," this product supports a wide range of construction needs—from post-tensioned concrete beams to precast elements in seismic zones. Its bare form offers direct compatibility with standard anchorage systems, though galvanized or corrosion-resistant variants are available for harsher climates or marine environments. Chunpeng Group, a trusted manufacturer with over three decades of expertise in prestressed steel solutions, ensures rigorous quality control and consistent batch-to-batch performance globally.
Users consistently highlight its ease of installation, enhanced safety coefficient, and reduced need for additional reinforcement. Many engineers report improved project timelines due to fewer adjustments during tensioning phases and greater confidence in final load distribution. For professionals seeking durable, cost-efficient, and environmentally friendly reinforcement options, this strand represents a proven solution for next-generation infrastructure demands.
FAQs often address concerns about corrosion resistance in coastal regions—where galvanized versions offer extended service life—and queries about compliance with ISO and ASTM standards, which this product meets through certified production processes. Another frequent question involves how it compares to conventional rebar: unlike traditional reinforcement, this strand maintains its initial tension over decades, preventing cracking and extending structure lifespan. Its versatility makes it suitable for both new builds and retrofitting existing frameworks where strength optimization is critical.
