Galvanized Steel Wire Rope (6×19+IWRC/IWS) for Construction & Industrial Lifting.
High-Tensile 5mm–32mm Wire Rope with ±3% Diameter Tolerance.
Engineered for rigging, hoisting, and structural bracing, this 6×19+IWRC wire rope combines a bright smooth surface with 1,370–2,160 MPa tensile strength. Certified to ISO 2408 and EN 12385-4, it features Class A galvanization (≥45g/m² zinc coating) for corrosion resistance in marine and industrial environments.
Key Features:
- Core Types: Independent Wire Rope Core (IWRC) or Fiber Core (FC)
- Diameter Range: 5mm (0.2″) to 32mm (1.26″) with ±3% precision
- Breaking Load: 1.2–126 tons (ASTM A1023)
- Applications: Crane slings, ship mooring, bridge cables, scaffolding ties

Manufacturing & Quality Control
- Wire Drawing: Cold-drawn from SAE 1006/1008 billets (≤0.08mm surface roughness).
- Galvanization: Hot-dip process with 99.99% zinc purity (ISO 1461 compliance).
- Stranding: Preformed helical strands reduce internal stress by 30% (DIN 3052).
- Testing: 100% proof load tested at 2.5×SWL (Safe Working Load).
Competitive Advantages
- Flex Fatigue Resistance: 250,000+ bend cycles before failure (ISO 3108).
- Abrasion Resistance: 15% longer service life vs. non-galvanized ropes.
- Customization: Cut-to-length (1–500m) with PVC sleeves or steel thimbles.
