What are GRP Open Mesh Gratings?

GRP Open Mesh Gratings are a high-strength, lightweight alternative to steel designed for a variety of applications across numerous sectors. These gratings are made from fibreglass, which contributes to their impressive durability and versatility. The open mesh design facilitates optimal airflow and drainage while providing superior slip resistance, making them an ideal solution for safe walking surfaces. 

The construction of these gratings involves weaving fine strands of glass fibres, which are then set in resin to create panels that are both strong and adaptable. This method of manufacture ensures that the panels are not only resistant to corrosion but also to fire, enhancing safety in industrial environments.

Open mesh grp grating panels are significantly lighter than traditional materials, such as steel, reducing the structural load and offering easy installation. 

GRP gratings are versatile allowing them to be used in a wide range of settings, from industrial flooring to walkways and even stair treads.

Their open mesh design is particularly beneficial in areas requiring efficient water drainage and ventilation. Additionally, the surface of these gratings can be gritted to increase slip resistance, further ensuring safety in potentially hazardous areas.


GRP open mesh gratings offer multiple benefits such as:

  • Anti-Slip Surface: GRP gratings are designed with safety in mind, featuring surfaces that significantly reduce the risk of slips and falls. This is achieved through specialised finishes, such as gritted textures, that enhance grip in various conditions, including wet or oily environments.
  • Fire Resistance: These gratings meet rigorous standards for fire safety, demonstrating resistance to flame spread and minimal smoke production. This characteristic is particularly important in sectors where fire risk is a critical concern, contributing to a safer workplace.
  • Superior to Steel Mesh Grating: GRP gratings offer a compelling advantage over steel mesh gratings. They provide comparable strength and durability while also being resistant to corrosion, chemical exposure, and environmental degradation, making them ideal for harsh or demanding conditions.
  • Lightweight: Weighing approximately half as much as steel, GRP gratings facilitate easier installation and handling. This reduced weight lowers the overall structural load, offering benefits in design flexibility and cost savings.


Choosing the right thickness for your gratings is crucial to meet the specific requirements of your project. Our fibreglass grating is available in many sizes including but not limited to: 25mm, 38mm, and 50mm.

Each size is designed to offer optimal performance and durability for various applications, ensuring you can find the perfect match for your needs, whether it’s for industrial flooring, walkways, or specialised applications.

Common Applications for Fibreglass Open Mesh Grating

Fibreglass open mesh flooring is versatile, supporting a wide range of applications across different sectors. Its unique properties make it suitable for:
  • Flooring Solutions: Ideal for industrial and commercial flooring, offering durability, slip resistance, and ease of maintenance. Its lightweight nature simplifies installation, particularly in large areas.
  • Walkways: Provides a safe, anti-slip surface for walkways in various environments, from industrial facilities to outdoor spaces, ensuring pedestrian safety even in wet or slippery conditions.
  • Industrial Flooring: Specially suited for harsh industrial environments where chemical resistance, fire retardancy, and durability are paramount. GRP grating can withstand heavy loads and aggressive substances commonly found in these settings.
  • Risers: An excellent material choice for risers in multi-level structures, offering both safety and aesthetic appeal. Its open mesh allows for efficient air flow and light penetration.
  • Chemical Plants: In environments where exposure to corrosive substances is a constant challenge, GRP grating excels due to its high resistance to chemicals, extending the lifespan of flooring and walkway structures.
  • Stair Treads: The anti-slip surface is particularly beneficial for stair treads, minimising the risk of accidents. GRP stair treads can be integrated into existing structures or used in new constructions.
  • Compliance with Standards: Meets and often exceeds the requirements of BS 4592, the British Standard for industrial type flooring and stair treads, ensuring compliance with safety and quality benchmarks.
