The Galvanized Steel Wire For Optical Cable

High-Performance Galvanized Steel Wire for Optical Cable Reinforcement

Engineered for Superior Tensile Strength & Corrosion Resistance

Our galvanized steel wire is specially designed for optical cable reinforcement, meeting stringent requirements of ISO 9001, ISO/TS 16949, and IEC 60794-1-21 standards. With wire diameters ranging from 0.6mm to 2.20mm and tensile strength up to 2160MPa, it provides critical mechanical protection for fiber optic cables in underground, aerial, and submarine installations.

Key Advantages Over Competitors:
✔ Precision Zinc Coating: Class B (60-115g/m²) ensures 15+ years corrosion resistance
✔ Custom Strength Grades: 1770MPa to 2160MPa via lead quenching treatment
✔ Tighter Tolerances: ±0.015mm for wires <1.0mm vs. industry ±0.025mm
