LINEAR FRAMELESS COVER

Flexible Coverage for Extended Drainage Lines

Perfect for large-scale water management, our linear frameless covers can be installed end-to-end to secure long utility trenches and continuous drainage channels. They offer a secure, high-capacity drainage system for parking lots, loading docks, and factory floors, streamlining installation by removing the need for expensive embedded metal frames.

Key Benefits:

  • Modular Installation: Designed with precision edges to be placed side-by-side seamlessly, covering any length of open concrete drainage rebate.

  • Rapid Water Runoff: Maximized, engineered slot designs ensure the rapid clearing of large volumes of surface water to prevent localized flooding.

  • Chemical & Salt Resistant: Completely unaffected by road salts, automotive oils, and harsh industrial chemicals common in large commercial zones.

  • Cost-Effective Setup: Dramatically reduces civil construction time and labor costs by allowing workers to simply drop the covers into pre-formed concrete channels.

Key Advantages of Fibera FRP Gully Cover Without Frame

Optimal Water Drainage

Precision-engineered slots ensure maximum surface water runoff, preventing flooding and pooling on roads, driveways, and industrial sites without compromising load-bearing strength.

100% Rust & Corrosion Proof

Unlike traditional cast-iron grates that degrade and stain over time, our FRP composite material is completely impervious to water, road salts, and harsh environmental chemicals.

Zero Theft Risk

Because our Fiber Reinforced Plastic has zero scrap metal value, these frameless gully covers eliminate the constant risk of theft, ensuring long-term safety and saving you costly replacements.

Heavy-Duty Strength

Rigorously tested to meet strict load-bearing standards, these covers are built to easily handle the stress of both pedestrian walkways and heavy vehicular traffic zones.

Lightweight & Easy to Handle

Significantly lighter than metal alternatives, our frameless covers ensure safe, single-person handling and quick removal for routine drain cleaning and maintenance.

Seamless Rebate Fit

Designed specifically to drop directly into pre-formed concrete or brick trenches, removing the need for an integrated frame and streamlining your entire installation process.

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.

  1. Ensure that you are using the right load capacity cover and frame based on vehicle/pedestrian movement. Please follow our load selection guide.

  2. Do not drop or throw FIBERA cover or frame while placing it on the floor. 

  3. Avoid impact of sharp and/or heavy objects on the cover and frame.

  4. Do not burn objects on or near the manhole cover, grating and frame.

  5. Use only supplied covers with appropriate FIBERA FRP frames.

  6. Use only FIBERA lifting key supplied with the FRP cover/grating to lift it.

  7. Occasionally remove the cover from the frame and clean the rim of the frame of any dirt/dust/pebbles.

  8. 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.
