Product Summary
GRP Beam Sections are pultruded structural profiles designed for use as primary beams, secondary supports, and load-bearing elements within GRP systems and standalone installations.
Compared to steel, GRP beams 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 beams can be used as standalone structural components or integrated into wider GRP systems such as walkways, platforms, bridges, fencing, handrails, and access structures.
Unlike traditional steel beam sections, GRP beams do not rust, corrode, or require protective coatings throughout their service life.
As a non-metallic material, GRP beams are electrically non-conductive and magnetically transparent, making them suitable for use around high-voltage equipment, substations, rail infrastructure, and sensitive electronic environments.
GRP beam sections are frequently used as part of complete GRP structures or as replacement sections where weight reduction, corrosion resistance, and ease of installation are critical.
Suitable Applications
GRP beam sections are widely used across structural, industrial, and access applications, including:
-
Walkway and platform support beams
-
Industrial flooring and access structures
-
GRP bridges and crossing structures
-
Handrail, balustrade, and fencing frameworks
-
Cable gantries and service supports
-
Water treatment works and utility installations
-
Rail, highways, and electrically sensitive environments
Key Benefits of Specifying GRP Beams
-
Non-Conductive – Electrically safe for use around high-voltage or sensitive equipment
-
Corrosion & Chemical Resistant – Suitable for aggressive, coastal, or industrial environments
-
Lightweight – Reduced handling effort and faster installation than steel beams
-
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 beams a preferred solution for infrastructure, utilities, and industrial projects where safety, durability, and long-term performance are critical.
Why specify GRP Beams?
GRP beam sections are increasingly specified as a direct replacement for traditional steel or aluminium beams in environments where corrosion resistance, electrical safety, and reduced maintenance are essential.
Unlike metal beams, pultruded GRP beams 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 beams also reduces handling, transport, and installation time on site, helping to lower whole-life costs without compromising structural performance.

Typical Profiles & Sizes
GRP beams are available in a wide range of depths, flange widths, and wall thicknesses to suit primary and secondary structural support applications.
Common GRP beam profiles include I-beams, H-beams, and box sections suitable for light-duty framing through to heavier load-bearing structures.
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 beam profile or size is suitable for your application, our technical team can assist with selection based on load requirements, environment, and intended use.
Environmental Performance
GRP beam sections perform exceptionally well in environments where metal beams 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 beams 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.
