11" 6x19 Class Galvanized Wire Rope – Detailed Specification

Nominal Diameter: 1 inch (25.4 mm)
Construction Type: 6×19 Class (6 strands, each strand contains approximately 19–26 wires)
Common Sub-Constructions:
- 6×19 Seale: Larger outer wires, excellent abrasion resistance
- 6×19 Warrington: Alternating coarse and fine wires, better flexibility
- 6×19 Filler Wire: Fine wires in the strand fill gaps, improves crushing resistance
Core Options:
- IWRC (Independent Wire Rope Core): Higher tensile strength, resistant to crushing, suitable for heavy-duty lifting
- FC (Fiber Core): Softer and more flexible, suitable for small bending radius, lower strength than IWRC
Surface Treatment: Hot-dip galvanized or electro-galvanized
Strength Grade: 1770 / 1870 / 1960 N/mm²
