GRP Grating, Flooring & Access Systems
GRP grating is widely used where corrosion, moisture, chemical exposure and ongoing maintenance requirements make traditional materials less suitable.
Applications include industrial flooring, rooftop walkways, access platforms, service gantries, water treatment facilities, rail infrastructure and marine environments.
Available in a range of panel depths, mesh configurations and resin systems, GRP grating can be specified to suit loading requirements, support centres and environmental conditions.
Design, fabrication and installation services are available for complete access systems, including:
- GRP grating and flooring
- Access platforms and walkways
- Modular handrail systems
- Access ladders
- Stair tread covers
- Supporting steelwork
Standard grating panels, fabricated components and complete access systems can be supplied to suit both new-build and refurbishment projects.

Why GRP Is Specified Instead of Steel, Timber & Aluminium
GRP combines corrosion resistance, low weight, slip resistance and electrical insulation in a material that requires minimal maintenance throughout its service life.
GRP does not rust and is unaffected by many of the environmental conditions that accelerate corrosion in steel structures. Different resin systems can be selected to suit specific operating environments and chemical exposures.
High strength relative to weight allows panels and structures to be installed with reduced manual handling requirements. Lower dead loads can also reduce demands on supporting structures.
Gritted and concave surface finishes provide underfoot grip in wet, oily and high-traffic environments. Surface finishes can be selected to suit site conditions and operational requirements.
Unlike steel and aluminium, GRP is non-conductive and offers inherent electrical insulation properties, making it suitable for electrical installations, utilities infrastructure and operational environments where conductive materials may present additional risks.
No painting, galvanising or corrosion treatment is required. Reduced maintenance requirements can significantly lower whole-life ownership costs when compared with traditional materials.

Frequently Asked Questions
GRP grating (Glass Reinforced Plastic) is manufactured using continuous glass fibre reinforcement combined with a thermosetting resin matrix. The glass fibres provide structural strength, while the resin system delivers chemical resistance, durability and environmental protection.
Panels are typically moulded in a controlled process to create a bi-directional load-bearing structure. The result is a lightweight, corrosion-resistant grating system suitable for industrial flooring, walkways, platforms and access structures.
Different resin systems can be selected depending on environmental exposure, including chemical, marine and fire-resistant applications.
GRP grating panels are available in a range of structural depths to suit varying load and span requirements. Common thickness options include:
- 25mm panels for pedestrian access and light-duty applications
- 38mm panels for general industrial flooring and platforms
- 41mm solid top panels where enclosed surfaces are required
- 50mm panels for higher load capacity and extended spans
Panel selection depends on loading conditions, support spacing and project-specific performance requirements.
Load capacity varies depending on panel thickness, mesh size and support span. Thicker panels such as 38mm and 50mm provide increased stiffness and improved load-bearing performance for industrial environments.
Structural performance should always be assessed against the intended span and applied load. Deflection limits, safety factors and maintenance loading should be considered during specification.
Load tables and span guidance can be provided to support compliant installation design.
Yes. Structural GRP profiles are manufactured in accordance with BS EN 13706, which defines minimum mechanical performance requirements for pultruded composite materials.
This standard covers tensile strength, flexural strength and modulus of elasticity, ensuring structural consistency and predictable performance.
Compliance with recognised standards supports safe specification in commercial, industrial and infrastructure projects.
GRP grating offers excellent resistance to corrosion and chemical attack. Unlike mild steel, it does not rust or require protective coatings to maintain performance.
The resin system can be selected to suit specific environments, including exposure to saltwater, industrial chemicals, wastewater treatment facilities and offshore conditions.
This makes GRP grating particularly suitable for utilities, marine, chemical processing and renewable energy sectors.
GRP grating can be manufactured using fire-retardant resin systems to meet specific fire performance requirements. Certain formulations offer low smoke emission characteristics and enhanced flame spread resistance.
Offshore and marine environments often specify fire-resistant or anti-static resin systems to meet safety regulations.
Resin selection should be aligned with project compliance requirements and operational risk assessments.
GRP grating panels are typically supplied with a gritted or concave anti-slip surface finish. These surfaces provide high levels of slip resistance, even in wet, oily or icy conditions.
Slip resistance performance is influenced by surface type, wear conditions and contamination levels. In most industrial environments, GRP grating offers significantly improved traction compared to traditional steel flooring.
Surface finish selection should reflect operational conditions and safety compliance requirements.
Yes. GRP grating panels can be cut to size using appropriate tools and fabrication methods. Panels can be trimmed to suit penetrations, pipework and irregular openings.
Edge sealing and correct fixing methods should be applied to maintain structural integrity and long-term durability.
For larger projects, pre-fabrication and off-site cutting can improve installation efficiency and reduce on-site labour time.
Yes. Design, fabrication and installation services are available for complete GRP access systems.
This can include supporting steelwork design, drafting and detailing services, panel fabrication and on-site installation.
Project-specific loading, layout and compliance requirements are considered during system design to ensure safe, long-term performance.
Yes. GRP grating systems are supplied and installed across the UK, supporting commercial, industrial and infrastructure projects.
Supply-only and full installation packages can be provided depending on project requirements.
