17.8 mm 1860 MPa High-Strength PC Strand – Premium Prestressing Steel for Modern Infrastructure
This high-performance prestressed concrete (PC) steel strand is engineered for demanding structural applications where superior tensile strength, dimensional accuracy, and long-term durability are essential. With a diameter of 17.8 mm and a nominal tensile strength of 1860 MPa, this 1×7 wire structure strand offers an optimal balance between load-bearing capacity and flexibility in complex construction environments. Designed to meet international standards such as ASTM A416, EN 10138, and GB/T 5224, it ensures consistent quality across global infrastructure projects—from bridges and highways to high-rise buildings and industrial facilities.
Manufactured using advanced cold drawing and stress-relieving techniques, the strand exhibits low relaxation properties, which significantly enhance its performance over time under sustained loads. This makes it ideal for post-tensioning systems where minimal creep and long-term stability are critical. The seven-wire configuration provides excellent fatigue resistance and uniform stress distribution, while the precision manufacturing process guarantees tight tolerances and reliable mechanical behavior even in harsh environmental conditions.
Key features include enhanced corrosion resistance through galvanization or specialized coatings, improved bond characteristics for bonded applications, and compatibility with various anchorage systems. Whether used in precast elements, bridge decks, or parking structures, this PC strand delivers exceptional value by reducing maintenance needs, extending service life, and supporting sustainable engineering practices.
Engineered for versatility, this prestressing cable supports both bonded and unbonded tensioning methods, making it suitable for diverse project types including railway viaducts, offshore platforms, and large-span civil engineering works. Its robust composition and compliance with global specifications ensure seamless integration into modern construction workflows, especially in regions prioritizing seismic resilience and climate adaptation.
Users consistently report increased confidence in structural integrity when deploying this strand in critical load-bearing zones. Engineers appreciate its predictable behavior during installation and long-term performance, while contractors benefit from reduced risk of premature failure and lower lifecycle costs. Many professionals highlight how its precise dimensions and consistent mechanical properties streamline formwork design and reduce rework on-site.
Common questions often center around its suitability for extreme climates—yes, weather-resistant variants are available for coastal or humid environments. Another frequent inquiry involves compatibility with existing anchorages: yes, it integrates smoothly with standard wedge-type and threaded anchoring solutions. Installation guidance typically emphasizes proper tensioning procedures and surface preparation to maximize effectiveness and safety.
