What is GRP Grating?
Glass Reinforced Plastic (GRP), often referred to as fibreglass grating or composite grating, is a lightweight, high-strength alternative to traditional steel grating.
Manufactured using continuous glass fibres and high-performance resin systems, GRP grating offers exceptional durability while remaining resistant to corrosion, chemicals and weathering. Unlike steel, it will not rust and requires very little maintenance, making it an ideal solution for harsh industrial and outdoor environments.
Its excellent strength-to-weight ratio, anti-slip surface and long service life make GRP grating the preferred choice for projects throughout the UK, Ireland and beyond.

Our GRP Grating Range
Relinea supplies a comprehensive range of GRP grating products suitable for a wide variety of industrial and commercial applications.
Moulded GRP Grating
Moulded GRP grating provides strength in both directions, making it ideal for walkways, platforms, access flooring and trench covers. It delivers excellent corrosion resistance and performs exceptionally well in demanding environments.
Pultruded GRP Grating
Pultruded grating is designed for applications requiring higher load-bearing capacity and longer spans. It is commonly used on industrial platforms, bridges and heavy-duty access systems.
Mini Mesh GRP Grating
Mini mesh grating features smaller apertures, improving heel safety while maintaining excellent drainage. It is ideal for pedestrian walkways, public spaces and areas where small tools or objects must be prevented from falling through the grating.
Heavy Duty GRP Grating
For projects with greater loading requirements, heavy-duty GRP grating provides increased structural performance while maintaining the corrosion resistance and durability associated with composite materials.
Benefits of GRP Grating
Corrosion & Chemical Resistant
GRP is highly resistant to moisture, chemicals and saltwater, making it suitable for aggressive environments where steel would require regular maintenance.
Lightweight
Significantly lighter than steel, GRP grating is easier to transport, handle and install, helping reduce installation time and labour costs.
Slip Resistant
Anti-slip surfaces improve safety for personnel working in wet, oily or hazardous conditions.
Long Service Life
GRP grating maintains its performance for 50+ years with minimal maintenance, reducing whole-life costs.
Electrically Non-Conductive
The non-conductive properties of GRP make it suitable for electrical installations and utility environments.
Low Maintenance
No painting, galvanising or corrosion treatment is required, reducing ongoing maintenance requirements.
Ease of Installation
The lightweight nature of GRP grating allows panels to be installed quickly and safely by a two-person team using simple hand tools
Typical Applications of GRP Grating
Our GRP grating systems are used across a wide range of industries and applications, including:
- Industrial walkways
- Access platforms
- Plant flooring
- Trench and drainage covers
- Stair landings
- Roof access walkways
- Riser void protection
- Maintenance platforms
- Chemical processing facilities
- Water and wastewater treatment works
- Marine and offshore environments
- Utilities infrastructure
- Renewable energy installations

Relinea’s D400 GRP Trench Covers and Gully Grids are the ultimate solution for heavy-duty drainage requirements in high-traffic areas.
Our Heavy Duty Solid Top Trench Cover is a sealed, non-draining cover designed for strength, security, and debris prevention. Now available in four load ratings. cases.
Why Choose GRP Instead of Steel?
While steel grating has traditionally been used for industrial flooring and access systems, GRP offers significant long-term advantages.
GRP will not rust, even when exposed to moisture, chemicals or coastal conditions. It requires minimal maintenance, is considerably lighter than steel and offers excellent slip resistance, helping to improve both safety and long-term value.
For many industrial environments, GRP provides a more cost-effective solution over its lifetime due to reduced maintenance requirements and increased durability.

GRP Grating vs Steel Grating Comparison
| Feature | GRP Grating | Steel Grating |
|---|---|---|
| Corrosion Resistance | Will not rust or corrode, making it ideal for wet, coastal, marine and chemical environments. | Can corrode when exposed to moisture, chemicals and saltwater unless regularly treated or protected. |
| Maintenance Requirements | Requires minimal maintenance with no need for painting, galvanising or ongoing corrosion protection. | Requires regular inspection, maintenance and protective coatings to manage corrosion. |
| Weight | Lightweight construction makes handling, transportation and installation easier. | Significantly heavier, often requiring additional labour and lifting equipment during installation. |
| Installation | Can often be installed by a two-person team using simple hand tools, reducing installation time and labour requirements. | Typically requires more labour, specialist equipment and additional handling due to increased weight. |
| Safety | Available with anti-slip surfaces and naturally non-conductive properties, helping improve workplace safety. | Can become slippery when wet and is electrically conductive. |
| Service Life | Provides long-term durability and reliable performance in demanding environments. | Service life can be reduced in aggressive environments due to corrosion and surface deterioration. |
| Chemical Resistance | Highly resistant to many chemicals and suitable for demanding industrial applications. | Resistance depends on the steel grade and protective coating used. |
| Site Disruption | Faster installation with fewer site requirements, helping minimise downtime and disruption. | Installation can require more preparation, equipment and time on site. |
| Whole-Life Cost | Lower lifetime costs due to reduced maintenance requirements and long service life. | Higher ongoing costs where corrosion protection, repairs and replacement are required. |
