It is important to consider the strength requirement when purchasing a manhole cover. All of our manhole covers conform to BS EN 124:2015 British standards classes, and should be considered when purchasing a manhole cover for a particular application. These classes are as follows:
A15: capable of withstanding a 15kN load (1.5 tonnes). Pedestrian areas only.
B125: capable of withstanding a 125kN load (12.5 tonnes). Car parks and pedestrian areas with very light traffic use.
C250: capable of withstanding a 250kN load (25 tonnes). Car parks and industrial sites with slow moving traffic.
D400: capable of withstanding a 400kN load (40 tonnes). Carriageways and hard shoulders.
