Product Summary
GRP Channel Sections are pultruded structural profiles designed for use as load-bearing rails, frames, supports, and secondary structural elements within GRP systems and standalone installations.
Compared to steel, GRP channels offer excellent resistance to corrosion, chemicals, moisture, and UV exposure, while remaining electrically non-conductive and lightweight. This makes them particularly suitable for safety-critical or hard-to-access environments where maintenance needs to be minimised.
GRP channels can be used as standalone components or integrated into wider GRP systems such as walkways, platforms, fencing, handrails, cable supports, and access structures.
Unlike traditional steel channel sections, GRP channels do not rust, corrode, or require protective coatings throughout their service life.
As a non-metallic material, GRP channels are electrically non-conductive and magnetically transparent, making them suitable for use around high-voltage equipment, substations, rail infrastructure, and sensitive electronic environments.
GRP channel sections are frequently used as part of complete GRP systems or as replacement sections where weight reduction, corrosion resistance, and ease of installation are critical.
Suitable Applications
GRP channel sections are widely used across structural, industrial, and access applications, including:
-
Walkway and platform frameworks
-
Handrail and balustrade systems
-
GRP fencing, screening, and perimeter structures
-
Cable management supports and trays
-
Plant access, ladders, and secondary steelwork replacement
-
Water treatment works and utility installations
-
Rail, highways, and electrically sensitive environments
Key Benefits of specifying GRP Channels
-
Non-Conductive – Electrically safe for use around high-voltage or sensitive equipment
-
Corrosion & Chemical Resistant – Suitable for aggressive, coastal, or industrial environments
-
Lightweight – Easier handling and faster installation than steel
-
High Strength & Dimensional Stability – Consistent performance from pultruded manufacture
-
Low Maintenance – No painting, coating, or corrosion treatment required
-
Long Service Life – Reduced whole-life and maintenance costs
This makes GRP channels a preferred solution for infrastructure, utilities, and industrial projects where safety, durability, and long-term performance are critical.
Why specify GRP Channels?
GRP channel sections are increasingly specified as a direct replacement for traditional steel or aluminium channels in environments where corrosion resistance, electrical safety, and reduced maintenance are essential.
Unlike metal channel sections, pultruded GRP channels do not rust, corrode, or degrade when exposed to moisture, chemicals, or UV radiation. As a non-metallic material, GRP is electrically non-conductive and magnetically transparent, making it particularly suitable for substations, rail corridors, utilities infrastructure, and high-voltage environments.
The lightweight nature of GRP channels also reduces handling, transport, and installation time on site, helping to lower whole-life costs without compromising structural performance.

Typical Profiles & Sizes
GRP channels are available in a wide range of web depths, flange widths, and thicknesses to suit structural and secondary support applications.
Common GRP channel sizes include C-channel and U-channel profiles suitable for light-duty framing through to heavier structural support.
Profiles can be supplied in standard stock lengths or cut-to-length to suit installation requirements, helping to reduce waste and installation time on site.
If you are unsure which GRP channel size or section is suitable for your application, our technical team can assist with selection based on load requirements, environment, and intended use.
Environmental Performance
GRP channel sections perform exceptionally well in environments where metal sections typically fail. Their resistance to corrosion, moisture ingress, UV exposure, and chemical attack makes them suitable for long-term use in coastal, industrial, and water treatment environments.
As a non-conductive material, GRP channels are widely used in electrically sensitive locations such as substations, rail corridors, utilities infrastructure, and high-voltage installations, where electrical safety and isolation are essential.
