GRP Unistrut Systems: A Smarter Alternative from Engineered Composites
In the world of structural support systems, performance, durability, and ease of installation are non-negotiable. That’s why more engineers, contractors, and facility managers across the UK are turning to GRP Unistrut systems from Engineered Composites.
If you’re seeking a strong, corrosion-resistant, and lightweight alternative to traditional steel frameworks, our GRP (Glass Reinforced Plastic) Unistrut-compatible range offers a reliable and future-proof solution.
From GRP channels and brackets to fixings and accessories, our systems are engineered for industrial, construction, marine, and utility applications—delivering strength, safety, and savings for every project.
Why Choose GRP Unistrut?
Corrosion Resistance
Steel may be strong, but it’s vulnerable to corrosion, especially in chemical-heavy or coastal environments. GRP doesn’t rust, rot, or degrade over time, even when exposed to moisture, salt, or industrial chemicals, making it the ideal material for harsh and high-risk settings.
Lightweight Yet Strong
GRP Unistrut components are up to 75% lighter than steel, making them far easier and cheaper to handle, transport, and install. Despite their reduced weight, they offer impressive structural integrity and can withstand heavy-duty industrial loads.
Electrically Non-Conductive
GRP is a non-conductive material, which significantly reduces the risk of electric shock and makes it a preferred choice in electrical, telecoms, and data infrastructure projects.
Low to Zero Maintenance
With no need for painting, treating, or corrosion control, GRP Unistrut systems keep ongoing maintenance costs to a minimum—saving time and resources throughout the product’s lifespan.
Our GRP Unistrut Systems and Components
At Engineered Composites, we supply a full suite of GRP Unistrut-compatible components that integrate seamlessly with existing steel systems. Whether you’re building from scratch or upgrading part of a structure, our range gives you total flexibility.
GRP Unistrut Channel
Our 41mm x 41mm GRP channel profiles match standard steel Unistrut dimensions, allowing for a mix-and-match install if needed. Made through the pultrusion process, each channel is reinforced for maximum strength, with excellent resistance to environmental and chemical exposure. Ideal for cable trays, pipe supports, framing systems, and beyond.
Brackets & Fittings
We offer a wide variety of GRP brackets, including:
- I Brackets – For inline joining of channels
- Angle Brackets – For 90° connections or shelf support
- Base Plates, Tee Connectors, and More – Designed for structural flexibility and stability
All fittings are precision-moulded for accurate alignment and stress distribution, ensuring secure frameworks in even the most demanding environments.
Fixings & Accessories
Every support system is only as good as its connections. That’s why we supply high-quality:
- Channel nuts and bolts
- Clamps and pipe supports
- Washers, end caps, and hold-downs
All fixings are compatible with GRP and steel Unistrut profiles, so whether you’re going all-GRP or creating a hybrid system, installation is smooth and simple.
Where Can GRP Unistrut Be Used?
GRP Unistrut systems are suited to virtually any environment where long-lasting, corrosion-resistant support structures are needed. Common use cases include:
Industrial Facilities
Install framing for cable trays, pipe runs, HVAC ducts, and switchgear,without worrying about corrosion or costly repairs.
Marine & Offshore Sites
GRP’s resistance to saltwater and UV makes it ideal for coastal and offshore platforms, ports, and shipyards.
Electrical & Telecommunications
Non-conductive, non-sparking GRP channels are perfect for electrical rooms, substations, and telecom/data cable infrastructure.
Chemical Processing Plants
GRP resists acidic and alkaline exposure, making it a safer and more durable choice in chemical handling environments.
Construction & Infrastructure
Use GRP Unistrut systems in bridge frameworks, tunnels, utility corridors, or above-ground installations where strength and safety are vital.
