Complete Buyer’s Guide to 6x17S (1-8-8) – IWRC Steel Wire Rope in 2025-26
6x17S (1-8-8) – IWRC Steel Wire Rope: Steel wire ropes play a critical role in the strength and safety of countless industrial operations—from construction and mining to oil rigs and ports. One of the most reliable options for demanding environments is the 6x17S (1-8-8) – IWRC Steel Wire Rope. Known for its durability, high load capacity, and robust internal construction, this rope is a preferred choice for applications where flexibility, wear resistance, and tensile strength are non-negotiable.
In this 2025–26 guide, the team at SSTC (Safe and Secure Trading Company) in Saudi Arabia walks you through everything you need to know about this powerful rope type—including specs, benefits, applications, selection tips, and responsible usage practices.
What Does 6x17S (1-8-8) – IWRC Mean?
Let’s start by decoding the name:
- 6x17S: Refers to the construction of the rope—6 strands, each with 17 wires.
- (1-8-8): Details the internal arrangement within each strand—1 center wire, 8 intermediate wires, and 8 outer wires.
- IWRC (Independent Wire Rope Core): Indicates a steel core instead of a fiber core, adding superior load-handling and stability under pressure.
This configuration strikes a smart balance between flexibility and durability, making it a go-to choice for heavy-duty lifting, hauling, and rigging.

Construction Overview
Seale Construction (S)
The Seale strand design uses larger outer wires for improved wear resistance, paired with inner wires that provide flexibility.
Benefits of Seale Construction:
- Stronger outer surface
- Longer service life in abrasive environments
- Uniform wear pattern
IWRC – Steel Core
The Independent Wire Rope Core:
- Increases tensile strength by 7–15% over FC (fiber core)
- Provides excellent resistance to crushing when used over pulleys or drums
- Handles higher operating temperatures
- Minimizes elongation under load
Advantages of 6x17S (1-8-8) – IWRC Steel Wire Rope
Exceptional Load Capacity
Due to its steel core, this rope supports heavier loads without significant stretch or structural fatigue.
Abrasion and Crushing Resistance
Perfect for winches, cranes, or sheaves where rope is repeatedly bent or dragged over surfaces.
Greater Longevity
Outlasts fiber core ropes in high-impact environments, reducing long-term replacement costs.
High Temperature Tolerance
Performs well in high-heat industrial settings (up to 200°C in some applications).
Stable and Durable in Harsh Conditions
From sandstorms to salty marine air, IWRC construction provides structural resilience in Saudi Arabia’s demanding environments.
Where Is 6x17S (1-8-8) – IWRC Steel Wire Rope Used?
Here are the most common industries and use cases in Saudi Arabia:
| Industry | Applications |
|---|---|
| Construction | Tower cranes, mobile cranes, rebar hoisting |
| Oil & Gas | Derrick lines, pipe hoists, platform lifts |
| Marine & Ports | Mooring ropes, towing lines, winch cables |
| Mining | Draglines, haul trucks, pulley systems |
| Utilities | Suspension cables, aerial lifting, cableways |
It is especially valued where strength and safety cannot be compromised.
Maintenance and Safety Tips
Proper care of your IWRC wire rope ensures longer service life and fewer failures.
Inspection Checklist
- Visual check for broken wires or corrosion
- Confirm lubrication is intact
- Look for kinks, birdcaging, or flattening
- Examine end fittings and connections
Lubrication and Cleaning
- Use penetrative wire rope lubricants
- Clean with solvent before re-lubrication
- Reapply after every 250 hours of use or exposure to sand/water
Storage
- Store in dry, shaded areas
- Keep away from corrosive substances or acidic materials
- Uncoil carefully to avoid twisting
How to Choose the Right Diameter
Choosing the right rope diameter involves:
- Minimum Breaking Load (MBL):
Ensure the rope’s MBL is at least 5 times your working load. - Pulley Compatibility:
Use a rope with a diameter at least 1/40th of the drum or pulley’s diameter. - Flexibility vs Strength:
Thicker ropes = More strength, but less flexibility
Thinner ropes = More bend, but lower capacity
Tip: Contact SSTC’s technical team for help matching your rope to your lifting gear.
Common Mistakes to Avoid
| Mistake | Impact |
|---|---|
| Using IWRC rope on small pulleys | Premature fatigue and internal wire break |
| Overloading without factoring safety | Rope snapping and system failure |
| Ignoring regular inspections | Sudden failure without warning |
| Improper installation (kinking) | Reduced lifespan, weak spots |
Always follow ISO 4309 and EN 12385-4 guidelines for wire rope installation and maintenance.
