Installing GRP Grating and Profiles — A Practical Guide
GRP is a material that can be processed and installed with relatively simple means compared with steel — but there are still important points to understand before installation begins. This guide gives a general overview, not a complete installation manual.
Summary
- GRP grating and profiles can be processed with the same standard tools used for timber — circular saw, jigsaw and angle grinder with the right blade.
- The material requires no welding, simplifying installation compared with steel and reducing the need for specialist skills on site.
- Correct fixings (clips, mechanical fasteners or adhesive depending on the product) are essential for both load capacity and maintaining the product's fire performance.
- Cut edges should be handled according to the manufacturer's recommendations to preserve the material's properties at the cut.
- We provide product-specific installation guides for each product — this guide gives a general overview.
Tools and processing
GRP can normally be sawn, drilled and processed with the same standard tools used for timber, provided the right blade type is used — usually tungsten-carbide-tipped blades. Cutting produces fine dust that should be managed with appropriate personal protective equipment, and the material should not be subjected to excessive heat build-up during cutting.
Fixing systems
The type of fixing required varies between products — grating is often fixed with clips or clamps, while profiles may require mechanical fasteners or approved adhesive systems. It's important to always use the fixing type approved for the specific product, both for load capacity and to avoid affecting any fire classification.
Cut edges and treatment
When cutting on site, cut edges should be handled according to the manufacturer's recommendations to preserve the material's properties. This is particularly important for products with a documented fire classification, where an untreated cut edge can in some cases affect the classified performance.
Safety during installation
The material's low weight reduces the risk of manual handling injuries compared with heavier materials like steel. Standard personal protective equipment still applies during processing, particularly eye and respiratory protection when cutting produces dust.
Before installation begins — what you should have ready
- Approved installation guide for the specific product
- Correct fixing type ordered and available
- Span and support conditions measured and confirmed
- Any fire-stopping requirements at penetrations clarified
Frequently asked questions
Do I need specialist tools to install GRP?
No, GRP can normally be processed with the same standard tools used for timber — circular saw, jigsaw and angle grinder with a suitable blade.
Can I cut GRP grating on site to fit?
Yes, that's one of the material's advantages. Always check the product's installation guide for recommended handling of cut edges, particularly if the product carries a fire classification that could be affected.
Do I need to weld GRP profiles in place?
No, GRP requires no welding. Fixing is instead mechanical, using clips, mechanical fasteners or an approved adhesive system depending on the product.
