In FLC cables outer layers of interlocking Z shaped wires are helically spun around an OSS core, avoiding the external agents get into the inner side of the cable. The combination of the closed design construction of a FLC cable, with Galfan (95% Zn / 5% Al) coated outer Z shaped wires and an internal zinc rich paste blocking compound that Teufelberger-Redaelli cables use result in a finished cable that has several stages of corrosion resistance.



  • Excellent axial stiffness
  • Optimum strength to weight ratio
  • Excellent fatigue resistance
  • Torque balanced
  • Suitable for cable clamping.
  • Four-stages Corrosion protection system.
  • Teufelberger-Redaelli patented anti-vibration solution (Surface Treatment)

Mechanical characteristics of steel wires:

  • Nominal Tensile Strength    1570 Mpa (after hot dip galvanizing)
  • Proof Stress Rp 0.2             1180 Mpa
  • Elongation at break              4% min on 250mm (EN12385-10)
  • Modulus of Elasticity            160 ± 10kN/mm²

Teufelberger-Redaelli Full Locked Coil (FLC) ropes are manufactured using a combination of helically wound, hot-dip galvanised, high strength steel round wires and interlocking Z-shaped wires.

The outer layers of Z-shaped wires are generally spun in opposite directions around a central core of round wires. Each individual wire is tested and verified for tensile strength, ductility, elongation at fracture, bending, torsional properties and adhesion of zinc coating in accordance with EN 10264 and EN 12385-10. Main properties: excellent axial stiffness, optimum strength to weight ratio, excellent fatigue resistance, torque balanced, excellent resistance to lateral forces meaning most suitable for cable clamping.
