Composite Manhole Cover Have Good Performance

Composite Manhole Cover Have Good Performance

Using the structure of pot bottom style (loading equally),other than the one of ribbing style (loading centrally),the strength supporting area will extend by more than ten or dozens of times. Therefore, the ability of strength sustaining will be more excellent.


Our Burglarproof Artistic manhole covers (shorted for GRP manhole cover) are made from composite materials such as glass fiber, resin, quartz, corundum etc..

Applying wear-resistant and climate-resistant materials on the relief sculpture layer so that the products can be long-term used under different environment.

Applying continuous reinforced fiber on the structure layer to ensure the products having sufficient sustaining ability. While some of other composite material manhole covers.


Infusing the manhole covers with the art of relief sculpture, designing individually to meet clients demands with artistic effect, promoting the culture feeling of our composite material manhole cover, the material is FRP, shorted for Fiber Reinforced Plastic;

Factory: Strictly in accordance with the EN124 standard production.

Composite Manhole Covers are removable plates which form the lid over the opening of a manhole. They prevent anyone or anything from falling into any manholes or sewage openings, and keep unauthorized persons out. OSDEON manhole covers have varying load tolerance, depending on the application.

A15 (Max Load=1.5 Tonnes): Areas which can only be used by pedestrians and pedal cycles.

B125 (Max Load=12.5 Tonnes): Pedestrian, pedestrian areas and comparable areas, car parks or car parking decks.

C250 (Max Load=25 Tonnes): For gully tops installed in the area of kerbside channels of roads which when measured from the kerb edge, extend to a maximum of 0.5m into the carriageway and a maximum of 0.2m into the pedestrian.

D400 (Max Load=40 Tonnes): Carriageways of roads (including pedestrian streets), hard shoulders and parking areas for all types of roads or vehicles.
