GRP Cable & Instrumentation Management

EXduro™ GRP CABLE MANAGEMENT & STRUCTURAL SOLUTIONS FOR HARSH ENVIRONMENTS

EXduro™ Glass Reinforced Plastic (GRP) cable management systems are built for performance in the most demanding environments. Lightweight, durable, and naturally resistant to corrosion and electrical conductivity, our cable ladders, trays, ducts, and instrumentation stands are designed to meet the rigorous requirements of modern industrial installations.

Each EXduro™ cable ladder is assembled with an additional nylon pin for enhanced structural integrity—offering better resilience during transport and installation. Our one-piece peaked covers provide robust, continuous protection for cables against weather and external elements.

EXduro™ delivers reliable, long-lasting cable management solutions with reduced lead times—keeping your projects moving efficiently.

WHAT IS EXduro™? ADVANCED GRP CABLE MANAGEMENT FOR HARSH CLIMATES

Treadwell’s EXduro™ range delivers high-performance GRP cable trays, ladders, ducts and supports, engineered to thrive where traditional metal-based systems fail. Built to withstand the corrosive nature of Australia’s and New Zealand’s environments, EXduro™ offers a corrosion-resistant, non-conductive, and lightweight alternative for industrial cable management.

EXduro™ GRP cable ladder systems are designed to meet NEMA 20C standards, offering reliable performance in demanding environments. A wide range of fittings—including tees, crosses, inward and outward bends, and strut options—provides options for diverse installation needs. The inclusion of EXduro™ slotted marine rungs allows for easy cable securing, enabling quicker installations.

Engineered with fire-retardant properties, corrosion resistance, UV stabilisers, and low electrical conductivity, EXduro™ shows outstanding performance in hazardous and corrosive environments. Despite being lightweight, the system offers exceptional structural strength, simplifying installation and reducing labour costs.

Complemented by GRP supports and instrumentation stands, EXduro™ delivers a fully integrated, low-maintenance cable management solution that meets stringent safety and compliance requirements. It is particularly well-suited for use in industries such as mining, marine, chemical processing, and wastewater treatment.

GRP CABLE LADDER AND TRAYS

Engineered for corrosion resistance, EXduro™ GRP cable ladder systems are suited for long cable runs. Their robust construction offers high load-bearing capacity, making them well-equipped to support the weight of heavy-duty cables over extended spans without compromising structural integrity. This durability ensures long-term performance with minimal maintenance, even in challenging industrial settings.

GRP SUPPORTS & BRACKETS

EXduro™ GRP support systems, struts, and ceiling mounts offer exceptional strength, corrosion resistance, and durability. They can improve the load bearing capacity of structures, without significantly adding to the weight or the structure.

GRP INSTRUMENT STANDS

EXduro™ GRP push button and instrumentation stands naturally non-conductive and corrosion resistant. They are easy to install, require minimal maintenance, and cost-effective compared to traditional metal options. Customisable for various configurations, they are compatible with industrial bases and allow quick on-site assembly, saving both time and money.
