6x7+FC 6X7+IWR Round Strand Steel Wire Rope

6x7+FC 6X7+IWR Round Strand Steel Wire Rope

Gostern 6×7 Galvanized Steel Wire Rope is manufactured from high quality carbon steel with excellent tensile strength, good flexibility and durable galvanized finish. This rope features 6 strands of 7 wires each (6×7) , with each strand constructed in a simple 1×7 single layer arrangement – one center wire surrounded by six outer wires . This simple construction offers good strength and abrasion resistance at a lower cost compared to more complex rope designs . Available with FC (Fiber Core) for added flexibility or IWR (Independent Wire Rope) core for increased strength and crushing resistance . Available in galvanized (zinc coated for corrosion resistance) finish as standard .

This 6×7 FC Wire Rope features a simple and robust construction that is highly resistant to abrasion and crushing, making it ideal for applications where the rope will be subjected to frequent bending over small sheaves or drums . However, due to the large diameter wires within each strand, 6×7 rope has poorer flexibility and lower fatigue resistance compared to 6×19 or 6×37 constructions . It is widely used as High Tensile Strength Wire Rope for guy wires and stays, as Mining Tie Rod Cable for underground roof bolting, as Tractor Control Cable for agricultural equipment controls, as Broom Handle Cable for industrial brooms and handles, and as General Purpose Galvanized Rope for tie-downs, fences, and structural applications . Available in diameters from 2mm to 16mm , with Grade 1570 MPa to 1960 MPa tensile strength options .

Construction Features:

• Simple 1×7 strand design: One center wire + six outer wires

• Large wire diameter per strand: Good abrasion resistance

• Galvanized finish: Excellent corrosion resistance for outdoor use

• Economical construction: Lower cost than complex rope designs

Limitations:

• Poor flexibility: Not recommended for small sheave diameters

• Low fatigue resistance: Not suitable for high-cycle bending applications

• Limited wire count: Less flexible than 6×19 or 6×37 ropes

Core Selection Guide:

• FC Core: Better flexibility, shock absorption – ideal for general use

• IWR Core: Maximum strength, excellent crush resistance – ideal for structural applications

Minimum Recommended Sheave Diameter: 42 × rope diameter (for FC core) | 48 × rope diameter (for IWR core)

Important Note: Do not exceed recommended working load limits. This rope is not suitable for applications with frequent bending over small sheaves due to its limited flexibility. Regular inspection for wear, broken wires, and diameter reduction is required.
