The 1x7 17.8mm 1860 MPa
PC Strand is a premium-grade, high-tensile prestressed concrete steel strand engineered for superior performance in modern construction applications. Designed to meet stringent international standards such as GB/T5224-2014 and ASTM A416/A416M:2012, this product delivers exceptional strength, durability, and long-term reliability—making it an ideal choice for engineers and contractors worldwide seeking robust reinforcement solutions. This prestressing steel strand features a compact 1x7 wire configuration, with each individual wire precisely drawn from high-carbon steel and heat-treated to achieve a tensile strength of 1860 MPa. Its low relaxation characteristics ensure minimal stress loss over time, maintaining structural integrity under sustained loads—a critical factor in bridges, highways, high-rise buildings, and precast concrete elements. The advanced manufacturing process guarantees consistent mechanical properties across batches, enhancing predictability during design and installation phases. Key advantages include a corrosion-resistant coating that protects against environmental degradation, especially in coastal or industrial zones where exposure to moisture and chemicals is common. This protective layer significantly extends service life while reducing maintenance needs—an essential consideration for sustainable infrastructure projects. Additionally, the uniform load distribution capability of the 1x7 structure minimizes localized stress concentrations, promoting safer and more efficient load transfer throughout reinforced concrete systems. Engineered for versatility, the 1860 MPa PC strand supports both bonded and unbonded tendon systems, offering flexibility in application methods. Whether used in post-tensioned slabs, bridge girders, or tunnel linings, its compatibility with standard anchorage systems ensures seamless integration into diverse engineering designs. The material’s proven track record in global infrastructure development underscores its value as a trusted component in civil engineering projects requiring precision, resilience, and longevity. Ideal for use in commercial, residential, and transportation sectors—from skyscrapers to railway viaducts—this
Prestressed Steel strand meets the rigorous demands of modern construction environments. It aligns with green building principles by minimizing material waste, enabling longer spans, and supporting lighter structural forms without compromising safety. Users consistently report improved project timelines due to reduced need for re-tensioning and fewer issues related to premature failure. Many professionals appreciate the consistency in performance across different climates and soil conditions, which contributes to predictable outcomes in both new builds and retrofitting operations. Common questions often revolve around its suitability for extreme weather conditions, compatibility with various grouting materials, and expected lifespan under dynamic loading. The answer lies in its dual-layer protection system and adherence to internationally recognized specifications, ensuring dependable results even in challenging operational contexts.
