High-Performance Pre-Stressed Concrete Steel Strand for Infrastructure Projects – Reliable, Durable & Cost-Effective
Engineers and contractors worldwide rely on this premium-grade pre-stressed concrete steel strand for demanding cast-in-place structural applications such as reinforced slabs, deep foundation piles, slope stabilization systems, and geotechnical support structures. Designed with innovation in mind, it eliminates the need for reserved ducts or complex grouting setups—streamlining construction timelines while reducing material waste and labor costs. Ideal for recoverable anchor cables, this product delivers exceptional value across large-scale civil engineering projects.
Manufactured to meet international standards including GB/T5224-2014, EN10138, BS5896, and ASTM A416, each batch undergoes rigorous quality control to ensure consistent performance under extreme conditions. With tensile strengths ranging from 1570 MPa to 1960 MPa, these strands offer superior load-bearing capacity, low relaxation properties, and excellent straightness—critical factors for long-term structural integrity in bridges, high-rise buildings, and tunnel linings.
Key Features:
- HDPE-Coated Surface: Provides corrosion resistance, ensuring longevity even in harsh environments like coastal regions or industrial zones.
- 7-Wire Construction: Enhances flexibility during installation and allows for random bending without compromising strength.
- Low Relaxation: Maintains tension over time, minimizing post-tensioning losses and enhancing overall efficiency.
- Optimized Friction Coefficient: Ranges between 0.04–0.1, enabling smooth anchoring and reduced stress concentration.
- Environmental Protection: Vapour-phase corrosion inhibitors and triple-layer wrapping protect coils during transport and storage.
The product is available in three core diameters: Φ12.70 mm, Φ15.20 mm, and Φ15.24 mm, each tailored for specific engineering requirements. The section area varies from 98.7 mm² to 140.0 mm², offering precise customization options based on design loads. Grease mass per meter ranges from 43 g/m to 50 g/m, ensuring proper lubrication and ease of deployment. Each coil weighs between 2,500 kg and 3,500 kg, with an inner diameter of 760 mm and outer dimensions up to 1,500 mm, making them ideal for efficient handling in shipping containers (20-foot capacity: 20,000–25,000 kg).
This Prestressed Steel strand excels in applications where durability, precision, and cost-effectiveness are paramount. Whether used in urban infrastructure, highway embankments, or offshore platforms, its proven performance supports sustainable development goals by extending service life and reducing maintenance needs. Its compatibility with unbonded systems further expands utility in modern construction techniques that prioritize modularity and adaptability.
Global users consistently highlight its reliability in challenging soil conditions and heavy-load scenarios. Contractors appreciate how it simplifies site logistics—no more drilling holes or installing corrugated tubes—and reduces downtime caused by premature failure or misalignment. Engineers praise the predictable behavior under dynamic loading, which contributes to safer, more resilient structures.
Common questions often revolve around suitability for seismic zones, compatibility with different grout types, and expected lifespan in aggressive environments. While results may vary depending on local conditions, extensive field testing confirms that when installed correctly using certified anchors and following best practices, this strand maintains optimal performance for decades—even in humid climates or areas prone to chemical exposure.
