7x19 Galvanized Steel Wire Rope
Available in 6mm, 8mm, 10mm, and 12mm diameters for lifting and hoisting applications.
Product Introduction
The 7x19 galvanized steel wire rope is constructed by twisting 7 strands, each containing 19 fine steel wires. With galvanizing treatment, it offers excellent flexibility and corrosion resistance. This multi-strand structure provides strong bending resistance for frequent turning and winding scenarios, while the galvanized layer protects against humid and acidic environments. Ideal for outdoor, marine, and mining applications, it serves as a flexible lifting device for equipment, elevator traction ropes, ship cables, and construction tie-down components.

Product Advantages
- Enhanced Flexibility: 7x19 multi-strand structure with numerous thin wires increases overall flexibility by over 40% compared to single-strand thick wires. Ideal for small radius pulleys and repeated bending applications with reduced fatigue wire breakage.
- Reduced Wear: Tightly arranged strands create a smooth surface with larger contact area on pulleys and drums, dispersing local pressure and minimizing wear rate.
- Superior Strength: Multi-strand combined force effect provides balanced tensile strength with 8% higher breaking force than 6×19 wire rope of same diameter, supporting higher loads in lifting and traction operations.
- Versatile Application: Balanced flexibility and strength suitable for dynamic scenarios (elevator traction, crane variable amplitude ropes) and static load-bearing components (building ties, ship mooring ropes).

Product Application
Common uses of 7x19 structure, 3.0-12mm diameter galvanized steel wire rope:
- Small Crane Lifting Equipment: Suitable for material lifting in workshops and small equipment lifting in building decoration. The multi-strand thin wire structure withstands frequent bending and impact during lifting, resisting fatigue wire breakage.
- Marine Platform Auxiliary Rope: Used for fixing platform equipment, pulling personnel baskets, and maintaining stable performance in complex environments like sea winds and waves, reducing maintenance and replacement frequency.
Product Certification
Our steel wire rope meets international production standards and holds multiple certifications including SGS, CE, and ISO.
