For this surface, rows in longitudinal direction alternate with embossed and debossed holes (d = 8 mm). The open area for standard grating widths is approximately 6 %. Graepel-Eco offers an excellent anti-skid effect and displacement as well as some drainage effect. The maximum embossed field is 460 mm. The width divider of 50 mm by means of which metric surfaces can be fully covered with standard gratings, makes this variant so economic. This makes it possible to dispense with fitting gratings which would have to be specially designed and manufactured.
Laid out in the longitudinal direction, by its straight rows of holes, Graepel-Eco makes it easy to safely guide wheels of wheelchairs and walking aids, suitcases and containers, bicycles and prams and can therefore be easily travelled on. This makes Graepel-Eco an excellent surface for escape and emergency routes, wheelchair ramps and handicap access lifting devices. On request, gratings of the Graepel-Eco variant can also be delivered with a perforated stepping edge on one side. We also offer straight steps in the Graepel-Eco variant, which come with a standard perforated stepping edge.
