Pedestrian friendly gratings

Whilst BS EN 124 provides no definition for a ‘Pedestrianised’ grating, there is an allowance in the Standard to reduce drainage apertures down to 5mm wide, where these may be preferred.

However, this restriction is avoided, wherever possible, as such gratings may not satisfy a scheme’s drainage requirements unless its lower waterway area is taken account of in the scheme’s design calculations. Therefore, pedestrianised gratings need to balance aperture size that prevents wheels and shoes from becoming lodged in its slot apertures, with the required waterway (drainage) area.

In theory, all gratings compliant to BS EN 124 should be pedestrian-safe as the aperture restrictions are aimed at maintaining traffic safety while providing drainage capability, which of course does not exclude various traffic types (including pedestrians) accessing other Group application areas not necessarily specifically intended for them but where they could reasonably be expected to be present.  E.g. Pedestrians walking across Group 4 (D400/E600 class) carriageways.

We offer a number of suitable gratings in our Highway and Unite ranges. Full details are available in the relevant products list below.
