GRP Rods and Tubes

GRP Tubes and Rods are incredibly versatile and used across numerous industries including water treatment, electrical engineering, rail infrastructure, telecommunications, marine platforms, and green energy systems such as solar and wind power. Thanks to their non-conductive and corrosion-resistant nature, these profiles are ideal for environments exposed to chemicals, moisture, or high electrical loads. They’re commonly found in measurement and filtration technology, agricultural structures, and cable management systems. At Engineered Composites, we offer GRP Tubes and Rods in a variety of standard and custom colours including black, white, and yellow, ensuring they suit both functional and visual project requirements.

GRP rods outperform traditional materials like wood or aluminium in strength, stability, and longevity. Unlike timber, GRP does not rot, warp, or absorb moisture, and unlike metal, it won’t corrode or conduct electricity. This makes GRP the preferred choice in safety-critical and moisture-prone environments such as waterworks, substations, and marine installations. Additionally, GRP rods are lightweight and easier to handle, transport, and install—reducing labour and logistical costs. These rods require no ongoing maintenance and are fire-retardant, UV-resistant, and safe in electrically sensitive areas. Simply put, GRP rods offer the strength of steel without its drawbacks.

Engineered Composites supplies GRP Tubes and Rods to a wide array of sectors throughout the UK, including rail, construction, marine, telecoms, chemical processing, agriculture, and electrical infrastructure. Our non-conductive and corrosion-resistant profiles are ideal for projects that require long-term reliability and safety. Whether you’re reinforcing a handrail on a rail platform or installing conduit systems in a water treatment facility, our GRP products deliver superior performance. We also support bespoke sector-specific needs, offering next-day delivery for urgent requirements, and custom lengths or colours for large-scale industrial installations.

From expert consultation to bespoke fabrication, we provide end-to-end support for your GRP structural needs. Whether you’re working on electrical insulation or marine reinforcement, we’re your reliable partner for high-performance GRP composite solutions.

Yes, GRP Tubes and Rods are specifically designed to perform in high-temperature and corrosive environments, making them ideal for sectors like chemical processing, wastewater treatment, and offshore installations. Engineered from glass reinforced plastic, these components are inherently resistant to acids, alkalis, solvents, and saltwater exposure. In thermally sensitive environments, GRP maintains dimensional stability and mechanical strength without degrading. Unlike metal tubes, which are prone to corrosion or heat-induced deformation, GRP profiles remain robust, safe, and maintenance-free. This makes them a preferred material choice for long-term reliability in aggressive or high-risk industrial applications.

Absolutely. All GRP Tubes and Rods supplied by Engineered Composites comply with key UK and EU safety and performance regulations, including EN 13706 for structural profiles and ASTM E84 for fire performance (where required). Our products also meet guidelines for electrical insulation, UV resistance, and chemical stability, ensuring suitability across public infrastructure, transportation, and utilities sectors. In addition to meeting technical specifications, we provide datasheets, test reports, and compliance certificates to help contractors and engineers meet regulatory obligations on-site. Safety, durability, and certification are integral to every GRP product we manufacture and deliver.
