4.8mm 5.0mm Prestressed Steel Wire 1670MPa-1860MPa for Concrete Reinforcement ASTM Standards

High-strength prestressed steel wire manufactured from premium high-carbon steel through advanced heat treatment and cold working processes. Designed for superior performance in concrete reinforcement applications.

• Cold Drawn Steel Wire: Smooth round wire with diameters 3-5mm, primarily used in railway sleepers and concrete pressure pipes
• Straightened & Tempered Steel Wire: Enhanced ductility and stress relaxation properties, supplied in large coils
• Low Relaxation Wire: Stress relaxation rate reduced to 1/3-1/4 of standard wire
• Galvanized Steel Wire: Zinc coating 250-350g/m² for corrosion protection in harsh environments
• Scored Wire: Surface notching for improved concrete bonding in pre-tensioning applications

Ideal for large bridges, roof trusses, crane beams, industrial precast floor slabs, railway sleepers, poles, pipe piles, and atomic energy power stations.

Produced through multiple drawing, stranding, and prestressing operations using materials such as SWRH82B and SWRH77B high-strength steel wires.

• Strict production and inspection according to international standards
• Competitive pricing based on real market conditions
• Secure transaction processing and financial protection
• Comprehensive after-sales support and service guarantees
