Hot-dip Zinc or Zinc-aluminium Coated Steel Wire Strand for Bridge Cables
The high-strength zinc- or aluminum-coated steel strands for bridge cables are made of high-carbon steel wire rods such as SWRS82B, SWRH82BCr, and SWRH82B-2, which undergo continuous drawing with large deduction stranding, hot dip galvanization, and stabilization to enable high tensile strength, low relaxation, and corrosion resistance to meet the standards of NF A35-035, GB/T 33369, and YB/T 152. Such steel strands are used in bridges, buildings, energy projects, and machines used in fields of hydraulic and geotechnical engineering.
