FRP / GRP Profile
Reinforce Technology Group Ltd delivers an advanced range of pultruded FRP / GRP profiles with high structural strength with outstanding corrosion resistance and long service life.
Our FRP / GRP pultruded profiles include box sections, H-beams, channels, angles, flats, and a full range of custom shapes. Lightweight and exceptionally strong, they provide reliable performance for any civil or infrastructure project.
FRP / GRP Profile Product
Tested to Your Specification
Every project has different requirements. We coordinate independent third-party testing through SGS and certified laboratories to your approved specification — whether that's chemical resistance, load rating, UV durability, or any other project-specific standard.
The data below represents the baseline material performance of our standard FRP/ GRP H-Beam profile, independently verified by SGS in accordance with EN and ISO testing standards.
For each project, your specified profile and configuration can be tested and certified prior to delivery, ensuring full compliance with the performance criteria required for your application.
Request a Product Testing Checklist to review available certification options for your project.

Why Choose our FRP / GRP Profile
FRP / GRP profiles offer a contemporary alternative to steel, timber, and aluminium, delivering high strength, corrosion resistance, and minimal maintenance. Built for long-term performance, they provide reliable structural support even in demanding industrial and environmental conditions.
Easy to transport, handle, and install than steel, whilst still having outstanding structural strength.
Lightweight & Strong
Corrosion Resistant
Engineered to withstand, moisture, and aggressive chemicals without rusting or degrading over time.
Non Conductive
A safe choice for electrical environments, rail infrastructure, and medical facilities where electrical conductivity must be eliminated.
Low Maintenance
No need for painting, coating, or specialised treatments. FRP maintains reliable performance throughout its long service life.
Customisable
Available in a wide range of profiles, wall thicknesses, Standards, colours to suit specific project requirements.
Lightweight and Strong
Easy to transport, handle, and install than steel, whilst still having outstanding structural strength.
Customised FRP / GRP Profiles for Industrial & Infrastructure Applications
Reinforce Tech designs and supplies customised FRP / GRP structural profiles engineered to replace traditional steel in demanding environments. Lightweight, corrosion-proof, and easy to install, our pultruded profiles provide long lasting performance with minimal maintenance. Whether used as standalone components or integrated into full framework systems, FRP / GRP offers a reliable, modern solution for industrial, marine, transport, and utility projects.
A Modern Replacement for Steel Frameworks
FRP / GRP profiles provide a high-strength, corrosion-resistant alternative to steel frameworks. They eliminate rust, reduce installation time, and remove the need for repainting or heavy lifting equipment allowing delivering a cleaner, more efficient construction process.
Industrial Access Structures
From walkways and gantries to maintenance platforms, FRP / GRP is widely adopted across factories, chemical plants, and rail. Its lightweight nature improves handling on site while ensuring long-term structural performance.
Marine & Offshore Environments
FRP / GRP excels in coastal and offshore conditions where steel and timber fail. It is commonly used for harbour access structures, and long-span service platforms exposed to saltwater.
Electrical & Utility Installations
Non-conductive and highly corrosion-resistant, FRP / GRP is perfectly suited for substations, switchgear areas, solar farms, data centres, and utility enclosures, providing long-term safety and reliability in electrically sensitive environments.
Water Treatment & Pumping Facilities
FRP / GRP maintains its properties in permanently wet and chemically aggressive settings. Typical uses include bund walls, tank frames, access platforms, and structural supports throughout treatment facilities.
Transport & Infrastructure Projects
FRP / GRP profiles are used in rail, road, and aviation infrastructure for inspection walkways, hand rails, service decks, signal structures, and bridge access points reducing installation effort and long-term maintenance.
Modular & Industrial Framework Systems
FRP / GRP offers strong, adaptable frameworks for modular buildings, ventilation housings, plant enclosures, and prefabricated units, supporting faster construction programmes and improved sustainability outcomes.
Testing and Compliance
FRP / GRP performance requirements vary by sector. Depending on the application, we provide testing to ASTM, BS EN, ISO standards that suits to your specification.
