Product Varieties
- Cold Drawn Steel Wire: Smooth round wire with diameters 3-5mm, primarily used in railway sleepers and concrete pressure pipes
- Straightened & Tempered Steel Wire: Improved yield strength and ductility for various prestressed concrete components
- Low Relaxation Wire: Stress relaxation reduced to 1/3-1/4 of standard tempered steel wire
- Galvanized Steel Wire: Zinc coating 250-350g/m² for corrosion protection in bridges and sewage structures
- Scored Wire: Surface notching for enhanced bonding with concrete in pre-tensioning applications
Manufacturing Process
Our prestressed steel wire undergoes multiple drawing processes with intermediate annealing to achieve optimal strength and toughness characteristics. The manufacturing includes heat treatment, cold working, and specialized processing for different wire types.
