"High-strength circular FRP covers, ideal for municipal sewer and drainage networks."
Reliable & Heavy-Duty for Municipal Networks
Designed for municipal sewer systems, commercial drainage networks, and residential applications, our circular FRP manhole covers provide exceptional strength and long-lasting reliability. Their classic round design ensures the cover can never fall through the opening, providing maximum safety for deep utility shafts and inspection chambers.
Key Benefits:
Fail-Safe Geometry: The circular shape guarantees the cover cannot drop into the manhole, protecting both workers and critical underground infrastructure.
Versatile Load Classes: Available in multiple load ratings—from pedestrian-friendly walkways to heavy-duty high-traffic roadways—to suit any project requirement.
Sewer-Safe & Corrosion Free: Unlike traditional cast iron, our composite FRP covers resist water, hydrogen sulfide gas, and harsh chemicals commonly found in sanitary sewer systems.
Easy Maintenance: Lightweight construction and ergonomic lifting points allow for quick, safe access for municipal maintenance crews.
"Versatile square and rectangular covers designed for secure access to utility trenches and electrical pits."
Versatile & Secure Access for Utilities
Engineered for inspection chambers, electrical pits, and telecommunication trenches, our square FRP manhole covers offer the perfect blend of high-load strength and practical accessibility. Unlike heavy cast-iron alternatives, these composite covers are incredibly lightweight, allowing maintenance crews to lift and replace them safely without heavy machinery.
Key Benefits:
Ideal for Urban Infrastructure: Perfectly shaped for standard utility pits and junction boxes.
Anti-Slip Surface: Manufactured with textured patterns to ensure pedestrian and vehicular safety in wet conditions.
Theft-Proof: 100% composite material with zero scrap value eliminates the risk of stolen covers.
Snug & Silent Fit: Precision-molded to sit flush within the frame, preventing the annoying rattling often caused by metal covers under traffic.
"Blend seamlessly into your landscape. Recessed covers designed for block paving and tile integration."
Broad Coverage & Seamless Integration
Ideal for larger utility vaults, wide drainage networks, and extended trenching, our rectangular FRP covers deliver unmatched durability without the cumbersome weight of traditional metals. Because they are resistant to water, chemicals, and extreme weather, they will not rust, warp, or crack over time.
Key Benefits:
Customizable for Large Openings: Available in extended sizes to cover wide trenches or large underground tanks securely.
Recessed Options Available: Can be designed as recessed covers, allowing you to infill them with block paving, concrete, or tiles so they blend invisibly into the surrounding landscape.
Heavy-Duty Load Capacities: Built to withstand everything from heavy pedestrian traffic in commercial plazas to vehicular loads in industrial facilities.
Corrosion-Resistant: Ideal for harsh environments, including chemical plants, sewer networks, and coastal areas where metal covers would quickly degrade.

Ensuring zero-failure performance and global compliance through rigorous BS EN 124 testing protocols.
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.
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.
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.
Prepare the concrete bed after considering the height of the Fibera FRP frame.
The Fibera FRP frame should be completely embedded in a minimum of M-20 grade concrete.
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.
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)
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.
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 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.
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.
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.
