GRP Manhole Covers are high-strength, corrosion-resistant composite covers engineered to protect underground utilities such as drainage lines, sewage networks, potable water pipelines, electrical chambers, and telecom duct banks. Built to meet rigorous international loading standards, they provide superior personnel safety, absolute zero scrap value to eliminate theft risks, and enduring resistance against corrosive chemicals, harsh weather, and heavy vehicular traffic.
Unlike traditional cast iron or ductile iron covers that rust, seize, rattle under traffic, and attract metal theft, our GRP composite covers are lightweight, non-conductive, and maintenance-free. Engineered with integral elastomeric seals, they prevent water ingress and stop foul sewage gas odors from escaping into surrounding urban environments.
We manufacture a comprehensive array of frame and cover geometries designed for roadways, pedestrian zones, and industrial facilities:
Standard design for municipal sewer manholes, stormwater inspection chambers, and mainline utility shafts. Impossible to fall through its own frame during maintenance.
Ideal for electrical draw pits, telecommunication cable pull chambers, valve enclosures, and multiple-cover continuous trench runs.
Slotted, high-intake hydraulic gully covers for curb drainage, roadway kerb inlets, parking lots, and stormwater collection sumps.
Designed with a hollow pan to accept paving blocks, tiles, granite, or epoxy screeds, allowing invisible architectural blending in plazas and lobbies.
Engineered with multi-ribbed undersides and heavy-duty composite locking mechanisms for subterranean pipeline networks and utility chambers.
Food-grade, dust-proof, and insect-proof access covers engineered specifically for concrete and GRP rooftop potable water tanks.
Our composite covers and frames are tested and certified to international BS EN 124 / ASTM standards to ensure appropriate safety factors for every vehicular or pedestrian zone:
| Class Rating | Test Load | Recommended Installation Environment |
|---|---|---|
| Class A15 | 15 kN (1.5 Ton) | Pedestrian pathways, footpaths, cycle tracks, private residential gardens, and rooftop overhead water tanks. |
| Class B125 | 125 kN (12.5 Ton) | Sidewalks, pedestrian precincts, private domestic driveways, and light commercial parking areas. |
| Class C250 | 250 kN (25.0 Ton) | Highway curb channels, roadside parking bays, commercial service yards, and utility access roads. |
| Class D400 | 400 kN (40.0 Ton) | Main highways, city carriageways, arterial traffic roads, container yards, and industrial estate roadways. |
| Class E600 | 600 kN (60.0 Ton) | Heavy industrial areas, container ports, logistics terminals, airport aprons, and dockside infrastructure. |
Cast iron is susceptible to severe corrosion from sewer gases (H₂S), rusts in coastal soils, and presents a high theft risk due to scrap metal value. GRP composite covers have zero scrap value (eliminating theft), never rust or corrode, weigh significantly less for injury-free handling, and suppress traffic impact noise.
Yes. Our Class D400 and E600 manhole covers are engineered with dense multi-axial composite reinforcement to withstand proof loads of 40 tons and 60 tons respectively, making them fully compliant for main highways, container ports, and heavy industrial terminals.
Our covers feature continuous tongue-and-groove profile channels fitted with high-grade elastomeric EPDM gaskets. When locked using stainless steel bolts or integrated quarter-turn lock mechanisms, the seal prevents sewage odors from escaping and stops surface stormwater run-off from overloading treatment networks.
Yes. We can integrate municipality or client logos and custom service identification badges (such as "SEWER", "DRAINAGE", "WATER", "ELECTRICAL", or "TELECOM") directly into the top mold face along with specific RAL color codes.
