Fiberglass Grating vs FRP Grating vs GRP Grating — Complete Guide
Fiberglass grating — also called FRP grating, GRP grating, GFRP grating, fiberglass grate, FRP grille or composite grating — is a corrosion-resistant open-mesh panel of glass fibre and resin. This guide explains the names, the types and how to specify the right fiberglass reinforced plastic grating for your project.
What is Fiberglass Grating?
Fiberglass grating is an open-grid structural panel made from continuous glass-fibre strands (or a mat reinforcement) bonded in a thermoset resin. It is the same product engineers call FRP grating (fiberglass reinforced plastic grating), GRP grating (glass reinforced plastic grating), GFRP grating (glass fibre reinforced plastic grating) or simply a fiberglass grate or FRP grille. In architecture and drainage, the same panel is often specified as a composite grating or fiberglass grille. Whatever the name, the material is the same: corrosion-resistant, lightweight and non-conductive — and 'fibreglass' is simply the British spelling of fiberglass.
ZeAllgrate manufactures both molded fiberglass grating and pultruded fiberglass grating, plus the clips and fasteners that complete the installation.
FRP vs GRP vs GFRP vs Fiberglass — Are They the Same?
Yes. FRP, GRP and GFRP all describe the same fibreglass-reinforced resin composite:
| Name | Stands For | Common In |
|---|---|---|
| FRP grating | Fiberglass Reinforced Plastic grating | North America, general industry |
| GRP grating | Glass Reinforced Plastic grating | UK, Europe, Middle East, Asia-Pacific |
| GFRP grating | Glass Fibre Reinforced Plastic grating | Engineering literature, academia |
| Fiberglass / fibreglass grating | Material name (US / UK spelling) | Everyday specification, building trade |
| Composite grating | Fibre-reinforced composite grating | Architecture, general engineering |
When you see FRP grate, GRP grate or fiberglass grate, or an FRP grille / fiberglass grille, the spec is describing the same open-mesh panel. If a buyer's drawing says one name and a supplier quotes another, they are compatible products — what matters is the resin, glass content and load rating, not the name.
Molded vs Pultruded Fiberglass Grating
There are two manufacturing methods, and the choice is set by span and load, not by the name you call the product:
| Type | Strength | Best For | Typical Span |
|---|---|---|---|
| Molded grating | Bi-directional, impact-tough | Walkways, platforms, trench covers, general industrial | Up to ~1.2–1.5 m |
| Pultruded grating | Uni-directional, ~2x stiffer | Long spans, heavy / concentrated loads, grating covers | Up to ~3 m and beyond |
Both are available in polyester, vinyl ester and phenolic resins for different chemical and fire requirements. See the selection process and load & span tables to choose correctly.
Fiberglass Grating in Other Languages
Because the same product is specified worldwide under many names, here is how the key terms translate — useful when you receive a spec or enquiry in another language:

Where Fiberglass Grating Is Used
Fiberglass / FRP / GRP / composite grating is specified wherever steel corrodes too fast, weight is a problem, or electrical insulation and slip resistance matter:
- Chemical plants and acid walkways
- Offshore platforms and marine decks
- Water & wastewater treatment walkways and covers
- Food & beverage washdown flooring
- Power plants and cooling towers
- Architectural facades, grilles and tree grates

Frequently Asked Questions
Fiberglass grating — also called FRP grating, GRP grating, GFRP grating or fiberglass grate — is an open-grid panel of glass fibre in a corrosion-resistant resin. It replaces steel grating where rust, weight, insulation or slip matter.
Yes — FRP (fiberglass reinforced plastic) and GRP (glass reinforced plastic) are two names for the same composite. GFRP and 'fibreglass' refer to the same material too.
A fiberglass grate, FRP grate or FRP grille is the same open-mesh composite panel as fiberglass grating — 'grate' and 'grille' are alternative terms used in industry and architecture.
