HEAVY-DUTY DRIVE-OVER GRATING
Uncompromising Protection for Vulnerable Roots
Engineered for demanding commercial environments, our heavy-duty tree gratings are reinforced to withstand the weight of maintenance vehicles, street sweepers, and light traffic. They protect vulnerable tree roots from severe compaction in shared parking lots and festival spaces without cracking, bending, or shattering.
Key Benefits:
High Load Capacity: Specially reinforced composite structure designed to easily handle vehicular loads in multi-use commercial zones.
Chemical & Salt Resistance: Completely impervious to road de-icing salts, automotive oils, and fertilizers that quickly degrade and rust metal grates.
Impact Resilient: FRP composite material absorbs impact and stress far better than brittle cast iron, preventing dangerous breakages under pressure.
Secure Fit: Rests firmly within its frame to prevent sliding, rattling, or shifting when rolled over by vehicle tires.
Key Advantages of Fibera FRP Tree Grantings:
Optimal Root Protection & Drainage
Designed with precision-engineered slots, our tree gratings ensure that rainwater and vital nutrients easily reach the tree's root system. This prevents harmful soil compaction from pedestrian traffic while promoting healthy, unrestricted growth for urban trees.
Zero Theft Risk (No Scrap Value)
Traditional metal grates are frequent targets for theft, leaving dangerous open pits on sidewalks. Manufactured from 100% composite Fiber Reinforced Plastic, Fibera FRP tree gratings have zero scrap value, providing a permanent, secure, and theft-proof solution for your city or property.
Pedestrian Safety & Anti-Slip Surface
Safety is our priority. Our tree gratings are designed to sit perfectly flush with the surrounding pavement, eliminating trip hazards. Furthermore, the textured, anti-slip surface ensures maximum grip for pedestrians, bicycles, and wheelchairs, even during heavy rain.
Lightweight & Easy to Install
Despite their heavy-duty load-bearing capabilities, Fibera FRP tree gratings are significantly lighter than their metal counterparts. This makes transportation, handling, and installation significantly easier, reducing labor costs and the need for heavy lifting equipment.
Testing and Quality Control
Ensuring zero-failure performance and global compliance through rigorous BS EN 124 testing protocols.
Load Capacity & Permanent Set Testing
Structural integrity is our absolute priority. Every Fibera FRP cover undergoes rigorous point-load capacity and permanent set testing, strictly adhering to the BS EN 124:2015 European standard. To simulate decades of real-world highway traffic, we subject our covers to advanced multiple-load cycling. This exhaustive testing process guarantees zero structural compromise and prevents permanent deformation under extreme vehicular stress.
Engineering Visual Inspection
Automated manufacturing meets meticulous human oversight. At Fibera, quality assurance is never left to chance. Immediately following the curing process, our dedicated structural engineers conduct a precise visual and dimensional assessment of every single unit. No product leaves our facility without successfully passing a stringent Quality Control (QC) checklist, ensuring flawless surface finishes and structural uniformity before dispatch.
Raw Material Purity & Batch Validation
The ultimate strength of an FRP composite lies in its underlying chemistry. We maintain strict, climate-controlled storage environments to protect our raw components from humidity, moisture, and particulate contamination. Before entering the production line, our in-house laboratory conducts comprehensive batch testing on all resins and fiberglass reinforcements, ensuring they perfectly match our exacting mechanical specifications.
Precision Manufacturing & Plant Calibration
Consistent manufacturing excellence demands flawless equipment. To eliminate process variations and unexpected machinery inconsistencies, Fibera operates under a highly proactive, preventive maintenance protocol. Our advanced compression molding infrastructure is routinely calibrated, inspected, and maintained by our technical team. This guarantees peak operational efficiency and ensures every FRP cover is molded to precise dimensional tolerances, batch after batch.
Standard Installation Guidelines
Proper installation is critical for long-term performance. Follow these mandatory steps for frame bedding and haunching to ensure your Fibera FRP covers maintain maximum structural integrity.
- Ensure that you are using the right load capacity cover and frame based on vehicle/pedestrian movement. Please follow our load selection guide.
- Do not drop or throw FIBERA cover or frame while placing it on the floor.
- Avoid impact of sharp and/or heavy objects on the cover and frame.
- Do not burn objects on or near the manhole cover, grating and frame.
- Use only supplied covers with appropriate FIBERA FRP frames.
- Use only FIBERA lifting key supplied with the FRP cover/grating to lift it.
- Occasionally remove the cover from the frame and clean the rim of the frame of any dirt/dust/pebbles.
- Do not leave the frame open without placing a cover or grating.
Installation Steps:
Prepare Bedding
Prepare the concrete bed after considering the height of the Fibera FRP frame.
Concrete Grade
The Fibera FRP frame should be completely embedded in a minimum of M-20 grade
concrete.
Clear Opening
Ensure that the manhole clear opening is equal or less than the opening of the Fibera
FRP frame. Frame resting should not be hanging without ground support.
Zero-Zero Leveling
Frame should be leveled using a spirit leveler and confirming that the air bubble in
the leveler remains exactly at the center (Zero-Zero Level)
Eliminate Gaps
Check gaps under the Fibera FRP Frame. Ensure that there are no visible gaps under
the frame and smooth bedding material with a trowel both inside and outside of the
chamber.
Final Enveloping
Use the remaining mortar to envelope the Fibera FRP Frame paying particular
attention to the corner areas. Smooth out the mortar with a trowel to ensure good
bonding with the frame and to avoid any initial cracks in the bedding material.

The Right vs. Wrong Way to Install
✅️ The Correct Method
(Flush & Supported)
The concrete bed is level, and the entire base of the FRP frame is resting solidly on the M-20 concrete. The top of the cover sits completely flush with the surrounding road/pedestrian surface.
❌ Wrong Method 1 (Unsupported Overhang)
The concrete bed is too wide, causing the inner lip of the FRP frame to hang over the manhole opening with zero support underneath. This will cause the frame to crack under heavy traffic loads.
❌ Wrong Method 2
(Uneven / Raised Frame)
The concrete bed is uneven or missing entirely under one side of the frame, causing the frame to sit at an angle or protrude above the road surface. This creates a tripping hazard and subjects the cover to severe impact damage from passing vehicle tires.
