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 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’.
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 mesh width (in mm)
Gratins mesh width inside
|13||51 x 51||45 x 45|
