Parafil™

The high-strength synthetic rope used where steel can't deliver.

ParaFil™ is the alternative engineers reach for when steel ropes corrode too quickly, weigh down a lift plan, interfere with a signal, or demand more maintenance than the asset can afford.

A parallel-fibre synthetic rope encased in a protective polymeric sheath, ParaFil™ has been in continuous service since 1967. It is specified for offshore infrastructure (umbilicals, riser support, and submarine power cable armouring), guy ropes for antennae and masts, overhead contact wire support for tram and light rail networks.

ParaFil™ is supplied as free-length rope or as terminated strops, precisely cut and ready for deployment. Each product is configured by selecting the right combination of core fibre and protective sheath to match the operating environment, from Arctic cold to chemical exposure to high-UV outdoor service.

Key Benefits of ParaFil™ Synthetic Ropes

High tensile strength for demanding load-bearing applications
High tensile stiffness for structural stability under sustained load
Lightweight with a strength-to-weight ratio steel cannot match
Excellent fatigue resistance for long-term cyclic loading
Electrically non-conductive with strong dielectric properties
UV resistant for outdoor service without sheath degradation
Thermally stable across extreme temperature ranges
Corrosion-free, even in salt water and chemical environments
Effectively maintenance-free with field-proven service lives over 40 years
Unaffected by water, ice, and harsh weather conditions

ParaFil™ Rope Terminations

ParaFil™ ropes are paired with proprietary end-fittings engineered specifically for the parallel-fibre core. The barrel-and-spike termination transfers load through friction alone, without bonding, adhesives, or compounds, and is capable of transmitting forces in excess of 100% of the rope's nominal breaking load.

Three standard termination forms are available (Fork, Eye, and Pre-Stressing), with bespoke designs frequently developed for specific project requirements. Custom low-weight, low-profile, and high-corrosion-resistance variants have been produced for applications ranging from broadcast mast guying to subsea systems.

ParaFil™ terminations are designed exclusively for our rope systems. Third-party terminations will compromise the integrity of the connection and reduce overall system performance. We recommend discussing your application with our team to specify the right termination at the design stage.
