GRP grating is one of the most popular materials used for industrial and commercial walkways, offering excellent slip resistance, durability and low maintenance. It is widely specified in environments where safety, corrosion resistance and long service life are essential.
This guide explains why GRP grating is so well suited to walkways and what to consider when choosing the right specification.
Why GRP Grating Is Ideal for Walkways
Walkways are high-traffic areas where safety is critical. GRP grating provides several key advantages over traditional materials:
-
Anti-slip surface as standard, even in wet or oily conditions
-
Corrosion resistant, ideal for outdoor and industrial environments
-
Lightweight, reducing installation time and handling risks
-
Low maintenance, with no rusting or repainting required
-
Non-conductive, reducing electrical and thermal hazards
These benefits make GRP grating a reliable long-term solution for both internal and external walkways.
Standard Mesh vs Mini Mesh for Walkways
Choosing the correct mesh type is important for walkway safety.
Standard GRP grating offers excellent drainage and is suitable for general access routes.
Mini mesh GRP grating features smaller openings, improving pedestrian comfort and reducing trip risk. It is often preferred where walkways are used frequently or by non-industrial personnel.
Choosing the Right Grating Thickness
The correct grating thickness depends on:
-
Span between supports
-
Expected foot traffic
-
Load requirements
Common walkway thicknesses include:
-
14mm for light-duty pedestrian access
-
25mm to 38mm for most industrial walkways
-
50mm for heavier-duty applications
Using the correct thickness ensures the walkway remains safe and stable over its service life.
Slip Resistance and Safety
GRP grating is manufactured with a gritted surface to provide high slip resistance. This is particularly important for walkways exposed to:
-
Rain and moisture
-
Oil or grease
-
Chemical residues
High-visibility colours such as safety yellow can also be used to clearly define walkway routes and edges.
Fire Performance
Most GRP grating used for walkways is manufactured using fire-retardant resins and complies with BS476 Part 7 (Class 1) for surface spread of flame. This makes it suitable for many industrial and commercial environments where fire performance is required.
Typical Walkway Applications
GRP grating is commonly used for:
-
Industrial walkways
-
External access routes
-
Platforms and mezzanines
-
Water treatment and processing plants
-
Manufacturing and engineering facilities
Installation and Fixings
GRP walkway grating is typically installed using:
-
M fixing clips to secure panels
-
C fixing clips to join adjacent panels
Correct fixing ensures the grating remains secure while allowing for thermal movement.
Is GRP Grating Right for Your Walkway?
If your walkway requires slip resistance, durability and minimal maintenance, GRP grating is often the best choice. Selecting the correct mesh, thickness and fixing method ensures a safe and long-lasting installation.
