High-Tensile pc steel strand – Premium Prestressed Concrete Reinforcement for Global Infrastructure Projects
Engineered for superior performance in demanding structural applications, high-tensile prestressed concrete (PC) steel strand is a critical component in modern construction systems where strength, durability, and long-term reliability are paramount. Manufactured under ASTM A416/A416M standards, this product delivers exceptional tensile capacity while maintaining flexibility for efficient installation in bridges, high-rise buildings, precast elements, and other reinforced concrete structures worldwide.
Each strand consists of seven high-strength carbon steel wires twisted into a helical configuration—offering uniform load distribution and enhanced resistance to stress corrosion cracking. Designed specifically for use in post-tensioned and pre-tensioned concrete systems, it provides the necessary initial tension to counteract future compressive stresses, significantly improving crack control, deflection behavior, and overall service life of the structure.
Key features include a nominal diameter of 15.24 mm (0.600 in), with tight dimensional tolerances (+0.65/-0.15 mm), ensuring compatibility with anchorage systems across international specifications. The minimum breaking strength reaches 260.7 kN (58,600 lbf), while the steel area measures 140.0 mm² (0.217 in²). At 1% elongation, the strand exhibits a minimum load of 234.6 kN (52,740 lbf), demonstrating excellent elastic response under sustained loads—a crucial factor for low-relaxation performance in long-span structures.
The material composition involves heat-treated high-carbon steel wires, optimized for maximum yield strength without compromising ductility. Available in both bare and galvanized variants, these strands offer versatility for diverse environmental conditions—from coastal regions requiring corrosion protection to inland areas where mechanical integrity takes priority. Additionally, weather-resistant and anti-corrosion options are available for extreme climates or aggressive exposure environments such as marine infrastructure or industrial facilities.
This premium-grade PC Strand is widely used in civil engineering projects including highway overpasses, railway viaducts, parking garages, dams, and wind turbine foundations. Its compatibility with unbonded systems further expands utility in complex architectural designs where movement and thermal expansion must be accommodated without compromising structural safety.
Trusted by global contractors and engineers, Chunpeng Group has over three decades of experience producing top-tier Prestressed Steel solutions. Their commitment to innovation, quality assurance, and sustainable manufacturing practices ensures consistent performance across thousands of projects from Europe to North America, the Middle East, and beyond.
Customers often highlight how this strand reduces maintenance costs over time due to its minimal relaxation properties—especially important in large-scale infrastructure where early failure risks are unacceptable. It also simplifies project timelines because of reliable splicing and anchoring methods that meet international engineering codes.
Common inquiries focus on whether the strand meets specific regional building codes (e.g., Eurocode 2, ACI 318, or BS 8110), which it does when sourced through certified suppliers. Another frequent question concerns surface treatment: while standard versions are bare, galvanized coatings provide added protection against moisture ingress and chloride penetration—ideal for harsher environments. Installation best practices recommend using compatible wedges and ducts to maximize bond efficiency and avoid premature fatigue.
For professionals seeking durable, high-performance reinforcement for prestressed concrete applications, this steel strand represents an industry-standard solution backed by rigorous testing, proven field performance, and global acceptance.
