Applications of FRP/GRP/SMC manhole covers:

1.) Underground Electrical Installations: Sump pits, Traffic lights, Street lighting, Fiber optic cable ducts; 
2.) Telecommunications: Connection chambers, Water, Gas, Petrol-chemical installations. 
3.) Urban Building Solutions: Pedestrians and comparable areas, Car parking decks, Gully tops. 
4.) Road Construction: Road cover and the load is suit for all the road vehicles.

How to choose a suitble manhole cover load capacity?

The manhole covers load capacities can be divided into 6 catagories:

Catagory 1: Class A15( Load 15KN or 1.5T - Wheel load 0.5T )

Areas where can be used by footways, pedestrains ares, side walking ways, or pedal cyclists.

Catagory 2: Class B125(Load 125KN or 12.5T- Wheel load 3T)

Areas where can be used by footways, pedestrians areas, car parks, driveways, etc.

Catagory 3: Class C250(Load 250KN or 25T - Wheel load 5T)

Roads for relatively slow moving traffic, i.e. minor residential, cul-de-sacs, pedestrian precincts and yards.

Catagory 4: Class D400(Load 400KN or 40T - Wheel load 11.5T)

Areas such as power stations, carriageways, hard shoulders, parking areas for all vehicle types. For high density traffic conditions we recommend the use of a vibration resistant locking system.

Catagory 5: Class E600(Load 600KN or 60T - Wheel load 20T)

Suitable for some airfield pavements, dockyards,other areas where single slow moving wheel loads up to 20T maybe encountered.

Catagory 6: Class F900(Load 900KN or 90T - Wheel load exceed 20T)

Aircraft hardstandings and taxiways at civil airports, container ports and dockyards where individual wheel loading exceed 20T)
