Key Performance Features
Strong Corrosion Resistance
High resin content and non-metallic construction provide excellent resistance to acids, alkalis, salt water, and industrial chemicals. Suitable for harsh environments where steel gratings may corrode.
Bi-Directional Strength
One-piece moulded construction ensures uniform strength in both directions, allowing efficient load distribution with minimal structural support requirements.
Anti-Slip Safety
Available surface finishes:
- Quartz Grit: High slip resistance
- Meniscus (Concave): Enhanced drainage and grip
- Smooth: Easy cleaning applications
Low Maintenance
- No rusting or corrosion
- No painting required
- Easy to clean
- long service life
Material Options
Resin Systems
- Isophthalic Polyester (ISO): Standard industrial applications
- Vinyl Ester (VE): Enhanced chemical resistance
- Phenolic: Fire-retardant applications
Color Options
- Yellow (RAL 1023)
- Green (RAL 6010)
- Grey
- Custom colors available

FAQ
What is the mesh size of 38mm moulded FRP gratings?
38mm moulded FRP gratings feature 38mm x 38mm square mesh openings with 7mm top bars and 5mm bottom bars. This provides 40-60% open area for drainage and visibility while maintaining structural strength.
What are the standard panel dimensions?
Standard 38mm FRP grating panels measure 1220mm x 3660mm (4ft x 12ft) with weight of 18.1-19.5 kg/m². Custom panel sizes and cutting available for specific project layouts and installation requirements.
What load capacity do 38mm FRP gratings support?
38mm FRP gratings support uniform distributed loads up to 5000 kg/m² and concentrated loads up to 2000 kg depending on span and support configuration. Load tables specify safe working loads for each application.
Are 38mm FRP gratings corrosion resistant?
Yes. With 30-35% glass fiber and 65% resin content, 38mm FRP gratings resist acids, alkalis, salts, oils, and chemicals. Available in ISO polyester, vinyl ester, and phenolic resins for specific environments.
What surface options are available?
38mm FRP gratings offer quartz grit surface for high slip resistance, meniscus (concave) surface for enhanced drainage/grip, and smooth surface for easy cleaning. All meet industrial safety requirements.
Do 38mm FRP gratings meet fire standards?
Yes. 38mm FRP gratings meet ISO 9001:2015 quality standards and optional ASTM E84 Class 1 fire rating. Phenolic resin versions provide strong fire retardancy for high-risk applications.
What industries use 38mm moulded FRP gratings?
38mm FRP gratings are used in chemical processing, petrochemical, wastewater treatment, offshore platforms, food processing, power plants, marine facilities, and heavy industrial walkways requiring corrosion resistance and safety.
Are 38mm FRP gratings lightweight?
Yes. At 18.1-19.5 kg/m², 38mm FRP gratings are substantially lighter than steel grating for equivalent load capacity. This reduces structural support requirements and installation costs.
