Offshore (PH)
Intergrate® PH GRP gratings are produced with a high-quality patented phenol resin combined with a continuously woven fiberglass pattern.
Types of resin
When choosing the type of resin, you need to determine the extent to which a grating must be fire-resistant.
- PH-XFR
- PH-XFR is a resin that is extremely suitable for a highly corrosive and offshore environment and is extremely fire-resistant with ultra low spreading of smoke. This type of resin has a flame propagation index of 0 and a smoke index of less than 10 in accordance with the ASTM E-84 tunnel test. The abbreviation XFR stands for ‘Extra Fire-Retardant’.
Anti-slip class
As standard, all Fiberstruct GRP gratings are produced with an anti-slip class in accordance with BGR 181 and DIN 51130. The slip-resistance of surfaces is categorised in anti-slip classes. These GRP gratings satisfy anti-slip class R13 (greater than 35°, extremely high coefficient of friction).
| Class | Angle of inclination |
| R 9 | 6° - 10°, low coefficient of friction |
| R 10 | > 10° - 19°, normal coefficient of friction |
| R 11 | > 19° - 27°, good coefficient of friction |
| R 12 | > 27° - 35°, high coefficient of friction |
| R 13 | > 35°, very high coefficient of friction |
Available mesh widths
Fiberstruct GRP gratings are available in the following thicknesses and mesh widths:
|
Grating thickness (in mm) |
Grating mesh width (in mm) centre-to-centre |
Gratins mesh width inside (in mm) |
