| High Light | High Carbon Prestressed Concrete Steel Strand ，Prestressed Concrete Steel Strand 12.7mm ，Low Relaxation 7 Wire Prestressing Strand | ||
Prestressed steel strands are manufactured from high-strength carbon steel wire rods through cold drawing, twisting, and stabilization processes. Each strand consists of 7 high-strength steel wires with a diameter of 15.2mm and tensile strength of ≥1860MPa. Produced in strict compliance with GB/T 5224-2014 standards, these strands feature surface treatments including hot-dip galvanizing or epoxy coating for excellent corrosion resistance. The relaxation rate is ≤2.5%, ensuring long-term stress maintenance.
