High-Strength Cold-Drawn PC Steel Wire for Prestressed Concrete Applications
Engineered for superior performance in modern construction, this premium cold-drawn prestressed steel wire offers exceptional mechanical properties and dimensional precision. Manufactured using a rigorous room-temperature drawing process, it transforms hot-rolled wire rods into high-tensile products ideal for demanding structural applications worldwide. With a tensile strength range of 1,770–1,860 MPa and advanced work-hardening effects, this material delivers enhanced yield strength, improved surface finish, and tight tolerance control—making it a preferred choice for infrastructure projects requiring long-term durability and reliability.
Produced from high-carbon steel grades such as C6 to C8, the wire undergoes precise cold working that increases its resistance to deformation while maintaining ductility. Its low relaxation characteristics—less than 2% after 1,000 hours at 80% stress—ensure consistent load transfer over time, crucial for bridge decks, high-rise buildings, and precast elements. The elongation at break exceeds 2.5%, offering sufficient flexibility under extreme conditions without compromising safety or integrity.
Designed to meet international standards including ASTM A416 and EN 10138, these wires are commonly used to form seven-wire or nineteen-wire strands, which serve as essential components in post-tensioning systems. Whether applied in highway bridges, railway viaducts, or industrial flooring, the product supports efficient design practices by enabling longer spans, reduced concrete usage, and optimized structural efficiency.
Chunpeng Group, a globally recognized manufacturer with more than three decades of expertise in prestressed concrete materials, ensures every batch meets stringent quality controls. Their comprehensive portfolio includes ultra-high-strength strands, normal-tensile variants, galvanized options for corrosion protection, weather-resistant solutions for harsh environments, and unbonded systems tailored for complex installations. Additional offerings like anchorage kits and photovoltaic mounting solutions further enhance project versatility across civil engineering and renewable energy sectors.
Engineers and contractors alike praise this wire for its consistency, ease of handling, and compatibility with various tensioning methods. Its uniform diameter (4.0–7.0 mm) allows seamless integration into standard strand configurations, reducing installation time and minimizing potential errors during construction. As sustainability becomes increasingly important, this product contributes to greener infrastructure through minimized material waste and extended service life.
Common inquiries often revolve around its suitability for seismic zones, compatibility with epoxy-coated tendons, and performance in freeze-thaw cycles. The answer lies in its controlled microstructure and robust metallurgical properties, which provide resilience even under cyclic loading and aggressive environmental exposure. For users seeking durable, high-performance reinforcement that aligns with global best practices in structural engineering, this cold-drawn PC steel wire stands out as a reliable and future-ready solution.
