Product Description
Product Overview
Prestressed steel wire is a high-strength cold-drawn steel reinforcement used in the tension zone of prestressed concrete members. This advanced construction material significantly enhances concrete's tensile resistance, enabling more efficient structural designs with reduced material usage and lighter components.

Product Varieties
Cold Drawn Steel Wire
Smooth round steel wire delivered in coils (500-1000mm diameter), primarily used in railway sleepers and concrete pressure pipes.
Straightened and Tempered Steel Wire
Enhanced yield strength and improved ductility with superior stress relaxation properties. Supplied in large coils (1.5-2m diameter) for various prestressed concrete components.
Low Relaxation Steel Wire
Stabilized treatment reduces stress relaxation to 1/3-1/4 of standard tempered wire, increasing residual stress by 10-15%.
Galvanized Steel Wire
Hot-dip galvanized coating (250-350g/m²) provides superior corrosion protection for bridges, sewage pools, and other demanding environments.
Scored Steel Wire
Surface notching improves bonding performance with concrete, ideal for pre-tensioning construction methods.
