GRP Grating
ZeAllgrate GRP Grating Systems
As an established GRP grating factory and composite grating supplier, ZeAllgrate produces molded and pultruded GRP grating — also specified as glass reinforced plastic grating, GFRP grating, GRP grate, FRP grating or fiberglass grating — engineered for corrosive, wet and heavy-load industrial floors.
- Molded GRP grating: bi-directional strength, equal load both panel directions
- Pultruded GRP grating: long spans and heavy load with I-bar, T-bar and square bar profiles
- Heavy duty GRP grating for platforms, walkways and industrial flooring
- Resin systems: isophthalic, vinyl ester, phenolic, fire-retardant, UV resistant GRP grating
- GRP grating panels up to 1220 × 3660 mm; thickness 25 / 30 / 38 / 40 / 50 mm
- Non-conductive, spark-resistant, maintenance-free — 20+ year service life in corrosive service

GRP Grating Types & Resin Systems
Select the grating type and resin system matched to your environment — the same methodology our engineers apply to every quotation.
| Option | Best For | Key Property |
|---|---|---|
| Molded GRP grating | Platforms, walkways, trench covers | Bi-directional strength, 25-50 mm thick |
| Pultruded GRP grating | Long spans, pipe racks, heavy loads | I-bar / T-bar / square bar, high strength-to-weight |
| Iso resin GRP grating | General chemical exposure | Isophthalic polyester, 60-70 °C service |
| Vinyl ester GRP grating | Acids, alkalis, solvents | Superior corrosion resistance, 80-90 °C |
| Phenolic GRP grating | Fire-critical, low smoke | Phenolic resin, 120-150 °C |
| Fire retardant GRP grating | Code-required flame ratings | ASTM E84 Class A, flame spread ≤ 25 |
| UV resistant GRP grating | Outdoor & solar exposure | UV-stabilized resin systems |

Frequently Asked Questions
GRP grating — glass reinforced plastic grating, also called GFRP grating, GRP grate, FRP grating or fiberglass grating — is an open-mesh panel made from glass fibre embedded in a corrosion-resistant polyester or vinyl ester resin. It replaces steel and aluminium grating where rust, weight, electrical conductivity or ongoing maintenance are a problem.
Yes. GRP (Glass Reinforced Plastic) and fiberglass (fibreglass) grating describe the same engineered composite — glass fibre in resin. 'GRP' is common in UK/Commonwealth markets while 'FRP' (fiberglass reinforced plastic) and 'fiberglass grating' are the North American terms. ZeAllgrate molds and pultrudes all three names from the same ISO 9001 line.
We supply isophthalic (ISO) polyester for general chemical exposure, vinyl ester for strong acids, alkalis and solvents, phenolic for fire-critical low-smoke service, plus fire-retardant (ASTM E84 Class A) and UV-stabilized UV resistant GRP grating for outdoor and solar exposure. Each resin is matched against our certified chemical resistance data.
Yes. As a certified GRP grating factory, ZeAllgrate exports molded and pultruded heavy duty GRP grating to distributors and projects in 45+ countries, with wooden export crates, fumigation certificates, material/load certificates and full shipping documentation.
