Spiral Ribbed PC Wire - Prestressed Concrete Steel Wire
Ruibaolong Spiral ribbed PC Wire (also known as Prestressed Concrete Steel Wire) features a helical pattern that significantly enhances bonding force with concrete. Unlike standard plain wire, our spiral ribbed surface provides superior anchorage, making it the ideal choice for railway sleepers, pipe piles, and precast beams. We offer high-tensile, low-relaxation wire compliant with ASTM A648, BS 5896, and GB/T 5223 standards.

Spiral Ribbed PC Wire - Prestressed Concrete Steel Wire
Product Details
Ruibaolong Spiral Ribbed PC Wire, also known as Prestressed Concrete Steel Wire, features a precisely formed helical ribbed surface designed to significantly enhance bonding force with concrete.
Compared with standard plain PC wire, the spiral ribbed structure provides superior mechanical anchorage, making it an ideal reinforcement solution for railway sleepers, PHC pipe piles, precast beams, and other prestressed concrete components.
Our products are manufactured as high-tensile, low-relaxation PC wire, fully compliant with ASTM A648, BS 5896, and GB/T 5223 standards.
Application Range
Bridge construction (highways, railways, municipal overpasses)
Urban rail transit systems and subway tunnels
Railway sleepers and prestressed concrete poles
Water conservancy & hydropower projects
Nuclear power plant infrastructure
High-rise buildings and precast concrete components
Core Product Features & Performance Advantages
Enhanced Concrete Bonding
The uniform spiral ribbed geometry significantly increases the bond strength between steel wire and concrete, improving load transfer and crack control.
High Strength & Low Relaxation
Tensile strength up to 1860 MPa
Relaxation rate ≤ 1.5% after 1000 hours, ensuring long-term prestress stability
Customizable Specifications
Diameter, tensile strength, rib pitch, and coil weight can be customized to meet specific project or design requirements.
Excellent Durability
Superior fatigue resistance makes the wire suitable for prestressed components subjected to cyclic or long-term loading.

Production Process & Quality Control
Raw material processing → Descaling → Phosphating → Drawing → Straightening →
Medium-frequency quenching → Tensioning → Winding → Packaging → Inspection & Warehousing
Key processes such as medium-frequency quenching and precision tensioning are fully automated and strictly controlled to ensure:
Stable ribbed geometry
Consistent mechanical strength
Reliable low-relaxation performance
The entire production process is monitored to ensure full compliance with GB/T 5223-2014 Prestressed Concrete Steel Wire requirements.
Manufacturing Strength & Quality Assurance
Ruibaolong operates 6 specialized prestressed steel wire production lines supported by an independent testing laboratory.
Each coil undergoes comprehensive inspection, including:
Tensile strength testing
Elongation measurement
Spiral rib geometry verification
Only qualified products are released for shipment, ensuring stable quality, reliable performance, and long service life in demanding engineering applications.
