EXduro™ FRP CABLE LADDER & TRAY SYSTEMS FOR HARSH INDUSTRIAL ENVIRONMENTS
Treadwell’s EXduro™ FRP cable ladder and tray systems deliver a complete non metallic cable management solution for demanding industrial environments. Manufactured from fibre reinforced polymer, EXduro™ is naturally non-conductive, corrosion resistant and lightweight, making it ideal for power, instrumentation and RF sensitive zones where conventional metallic systems can introduce safety and durability issues.
The range covers:
- FRP cable ladder for heavy duty cable runs
- FRP cable tray and trough for lighter and mixed services
- FRP strut systems, supports and accessories for complete cable support frameworks
EXduro™ systems are engineered according to the requirements NEMA FG 1 up to a NEMA 20C classification, supporting high working loads over long spans. Where a longer span or higher load capacity is needed, Treadwell can design a custom EXduro™ cable ladder to meet site-specific requirements.
For operators in processing plants, refineries, water and wastewater treatment, mining, marine and power infrastructure, EXduro™ provides durable, low maintenance cable support that is easier to install and safer to operate than traditional steel alternatives.
Key Benefits
Non-conductive and safer around power
- FRP is electrically non-conductive, helping reduce the risk of touch and step potentials in substations, rail corridors, and high-voltage areas.
- No standard earthing or bonding is required for the ladder or tray itself, simplifying design and site installation compared to metallic systems.
Superior corrosion and UV resistance
EXduro™ components are manufactured from corrosion-resistant resins with UV stabilisers, providing long service life in chemical plants, coastal facilities and outdoor installations.
FRP will not rust, and is highly resistant to many acids, salts and industrial atmospheres where galvanised and even stainless steel can degrade.
High load capacity on longer spans
EXduro™ cable ladder is engineered up to NEMA 20C, which corresponds to approximately 148 kilograms per meter working load over a 6-meter span.
Longer spans can reduce the number of supports required, lowering material and installation costs for large runs.
Lightweight and easier to install
FRP cable ladder and tray are typically significantly lighter than stainless steel for equivalent load rating, reducing manual handling effort and cranage requirements.
Products can be cut and drilled on site with standard tools, with no hot work, no sparks and no re-galvanising or repainting of cut edges.
Reduced issues with dissimilar metals
Because EXduro™ is non-metallic, it avoids galvanic corrosion that can occur when a stainless cable ladder is fixed to carbon steel structures.
This simplifies detailing and reduces the need for isolating pads, sleeves and other protective interfaces.
Versatile configurations and accessories
EXduro™ encompasses cable ladders, slotted or solid base trays, troughs, FRP struts, and a full suite of fittings and supports, enabling non-metallic cable systems from primary runs to local supports.
Treadwell also offers enhanced rung designs that simplify cable tie-off and improve cable retention on critical runs.
Applications
Heavy industry and processing plants
EXduro™ FRP cable ladder is well suited to:
- Mineral processing plants and refineries, where corrosive atmospheres and wash down cycles rapidly attack metal supports
- Chemical and fertiliser plants with aggressive vapours and spill risks
- Zinc, nickel and other metal refineries where both corrosion and electrical safety are critical
Water and wastewater treatment
Cable ladder, tray and trough systems for water and wastewater treatment plants, including clarifiers, pump stations and odour control facilities
Ideal where hydrogen sulphide, chlorination, saline spray or constant moisture would shorten the life of steel cable supports
Power, renewables and substations
Substations and switchyards where non conductive cable management improves safety and can reduce earthing complexity
Solar and wind farm balance of plant, where long cable runs and harsh outdoor exposure demand durable, low maintenance supports
Marine and coastal infrastructure
Jetties, wharves and coastal plants using FRP cable ladder or deep troughs to route and protect power and control cabling over water
Applications where wave uplift, salt spray and tidal zones would severely impact metallic systems
Industrial services and mixed utilities
Mixed service runs carrying data, instrumentation, compressed air and small bore services on FRP tray and strut
Instrumentation stands, small frames and supports built from FRP strut to keep everything within a non metallic, corrosion resistant system
