FRP Moulded Grating
Fiberglass reinforced plastic (FRP) moulded grating is a high-performance composite panel for industrial flooring, walkways, platforms, trench covers and stair treads. Manufactured by interweaving continuous fiberglass roving with thermosetting resin in a heated mould, it delivers high corrosion resistance, light weight, spark-free conductivity, and long service life in harsh chemical, marine and offshore environments.
Why FRP Moulded Grating
Compared with traditional metal gratings, the most significant advantage of FRP moulded grating is its outstanding corrosion resistance. It resists acids, alkalis, salts, organic solvents and other chemicals, making it ideal for chemical, petroleum, sewage treatment and other corrosive environments. FRP grating is also lightweight, easy to install, electrically insulating, and flame-retardant — which is why it is widely used in electronics, power, paper, printing and dyeing, electroplating, marine exploration, equipment platforms, drilling platforms and walkways.
The surface of moulded grating can be supplied with anti-slip patterns, increasing safety in wet environments and adding wear resistance. Panels are available in yellow, green, gray, red and orange to suit aesthetic or functional needs.
Performance of FRP Moulded Grating
FRP grating has excellent corrosion resistance to acids, alkalis, organic solvents and salts in both gas and liquid media — performance unmatched by metal grating in corrosive environments. Resin choice (ortho, ISO or VE) is matched to the actual site requirements.
Key performance characteristics
- Excellent corrosion resistance to acid, alkali, salt, organic solvents and other chemicals — suitable for long-term use in strong corrosive environments.
- Electrical insulation — non-conductive; safe for power, substations and cable trenches.
- Flame retardant — high oxygen index (up to ~80 with phenolic resin).
- Anti-slip & wear resistance — anti-slip pattern or sand surface; withstands long-term foot traffic.
- Aging resistance — UV-stabilized; 20+ year outdoor service life.
- Fatigue resistance — high elastic modulus; withstands repeated loads.
- Easy installation — cut, drilled, spliced on site; bolt or clip fastening.
- Environmentally friendly — recyclable material; no harmful emissions produced.
- Aesthetic — multiple colors, smooth surface, easy to clean.
Surface types
- Concave — standard gritted top for general use.
- Sanded gritted — fine quartz finish for high-traction walkways.
- Smooth — for covered applications or where sand is undesirable.

FRP Moulded Grating with Cover Plate
Cover-plate gratings are formed by bonding moulded FRP grids with hand-laid FRP flat plates to create a single- or double-sided sealed structural panel. High strength, suitable for heavy-duty environments; effectively isolates odors, protecting the surrounding environment. Cover plate thickness 3–12 mm, designed to your specific load requirements.
