Product Description
7×7 Galvanized Wire Rope - Carbon Steel Core
Product Overview
7×7 galvanized steel wire rope features a construction where 7 steel wires form one strand, and 7 such strands are twisted into a complete wire rope. This wire contact steel rope includes an outer galvanized layer applied through hot-dip coating or electroplating processes to provide superior corrosion protection.

Product Features
- Strength Balance: Multi-layer steel wire twisting ensures uniform force distribution, stable breaking force, and reduced local fracture risk
- Excellent Flexibility: Compared to 7×19 structure, fewer but thicker wires provide sufficient strength while maintaining good bending performance
- Corrosion Resistant & Durable: Galvanized layer isolates steel wire from air and moisture, extending service life and reducing maintenance costs
Structure Comparison
| Structure | Wires | Flexibility | Torsional Resistance | Applicable Scenarios |
|---|---|---|---|---|
| 7×7 | 49 Wires | Moderate | Stronger | Light load fixation, small-scale traction |
| 7×19 | 133 Wires | Better | Weaker | Frequent bending and dynamic traction |
| 1×19 | 19 Wires | Poor | The Strongest | Rigid cable, static load-bearing |
Applications
Common uses for 7×7 structure, 1.2-5.0mm diameter galvanized steel wire rope include:
- Small Lifting Equipment: Lifting rigging for manual hoists and small electric hoists, balancing strength and flexibility
- Construction: Scaffolding tying, safety ropes for exterior wall operations, with corrosion resistance for complex outdoor environments
- Fishery & Aquaculture: Fixed ropes for net cages, towing ropes for fishing equipment, featuring outstanding resistance to seawater corrosion
