Saint-Gobain Pipelines, Stirling Lloyd and Bristol City Council – ?Grip-Top? an anti-skid covering for manhole covers
The creators of Grip-Top service covers have developed a combination of ductile iron manhole cover and surface treatment offering levels of grip comparable to road surroundings. It is the first product to comply with current CEN regulations and was specifically designed to meet the needs of motorcycle and scooter users who are extremely vulnerable to sudden changes in grip. Grip-Top is now being specified by roads authorities for use in critical locations.
