- Film Sets and Productions
- Corporate Functions
- Wedding Venues
- Public Gatherings
- Parks and Recreation
- Campgrounds and Festivals
- Historical Sites and Landmarks
Application Area
GFRP lawn covers offer advantages such as distributing weight, preventing soil compaction, and promoting grass growth underneath. They can be quickly installed and removed, making them practical solutions for temporary events. Proper installation and maintenance practices are essential to ensure that the grass remains healthy beneath the cover and can recover once the cover is removed.

DynaGuard Products : Unmatched Performance and Durability
Size Selection
- Clear Opening of the frame should not be smaller than the drain clear opening size.
- Shape of frame should be same as shape of drainage opening.
- If possible, always design drain according to industry standard sizes.
- O – Clear opening
- D – Cover Size
- F – Frame Size
- H – Frame Height
- h – Cover Thickness
Load Bearing Capacity Selection
Load 2.5T (LD) (Point Load/ Wheel Load 0.8T)
Areas where can be used by footways, pedestrians areas, side walking ways, or pedal cyclists.
Load 5.0T (LD) (Point Load/ Wheel Load 2.5T)
Suitable for use in areas with light Motor vehicle traffic underground parking decks in residential areas.
Load 10.0T (MD) (Point Load/ Wheel Load 3.0T)
Areas where can be used by footways, car parks, driveways etc.
Load 20.0T (MD) (Point Load/ Wheel Load 5.0T)
Roads for relatively slow moving traffic, i.e minor residential, r e s i d e n t i a l , cul-de-sacs and frequent traffic area.
Load 40.0T (MD) (Point Load/ 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 vibration resistant locking system.
Load 60.0T (MD) (Point Load/ Wheel Load 20T)
Areas submitted to high wheel loads such as ports and dikes or dock laterals.
Load 90.0T (MD) (Point Load/ Wheel Load 30T)
Areas subject to particularly high wheel loads such as runways
DynaGuard Installation and Maintenance
Please note frame is not load bearing and therefore has to be completely supported from all sides. For more specification follow instruction of installation.
Service-life
Dudhi DynaGuard FRP manhole covers have long durability Upto 50 Years
Storage & Handling
Transportation: Lay in flat of manhole cover with a pair of Frame and cover plate during transportation.
Handling: Bigger size of manhole cover is heavier in weight so engage two persons at least to carry in loading or unloading. To avoid damage of corners and edges, keep the cover plate in safe place during fixing of frame.
Background Preparation
The foundation of the chamber should be casting the concrete M-30 or even better, the frame around the concrete width should be around 200 mm.
For More Specification Follow Instruction of Dos or Don’ts
Application
Make sure that top level of the frame should match the road.
Prepare concrete bed considering height of the frame
Frame should be allowed to set in concrete for a minimum time of 48 hrs, before its use.
DynaGuard : Precautions
- Do not choose under load capacity it may get damage or harm full during traffic movement.
- During the process if any traffic run on the frame or cover will get damage.

- During fixing the frame have to fixed on chamber with proper position not along with cover plate. The cover plate should lay on the frame after completion of flooring work. For more specification Follow instruction of Dos or Don’ts.
Service-life
- Technical Service team offers solutions for application methodology.
- Intermediate site inspections and feedback.
- Recommend appropriate sizes for fixing and finishing.
- Large distributed manufacturing capacity hence easy available in time.
