Corrosion Resistant EN124 Certified SMC Manhole Cover for Drainage Systems
Product Description:
Our SMC manhole cover combines high tensile strength and impact resistance, making it ideal for infrastructure projects. With a smooth anti-slip surface and corrosion-proof core, it ensures long-term reliability. It’s compliant with international standards and can be tailored for public utilities, electric chambers, or sewer systems.
Product Details:
This rectangular SMC manhole cover is purpose-built for municipal wastewater applications in urban and suburban infrastructure projects. Manufactured using Sheet Molding Compound (SMC), this composite material offers superior performance characteristics compared to traditional concrete or cast iron alternatives. The manhole cover meets the D400 load-bearing standard under EN124, making it suitable for light vehicular traffic zones, residential neighborhoods, sidewalks, and greenbelt installations.
Its rectangular design is especially advantageous for sewer access points that require a larger opening or easier alignment with linear trench systems. The flat profile allows seamless integration with concrete or asphalt surfaces, ensuring both pedestrian safety and aesthetic uniformity. Reinforced ribs on the underside increase structural integrity, allowing the cover to maintain shape and strength under dynamic loads.
One of the most notable features is its corrosion resistance. Municipal wastewater environments often involve exposure to chemical residues, gases like hydrogen sulfide, and moisture saturation. This SMC manhole cover remains stable and unaffected, avoiding the rust, pitting, or erosion typically seen with cast iron. This not only improves the service life of the product but also reduces long-term maintenance costs for municipalities.
Weighing 40–60% less than its metal counterparts, the cover significantly eases transportation and installation logistics. One or two workers can safely maneuver the cover without mechanical lifting equipment, reducing labor costs and improving site efficiency. Anti-slip textures are molded directly into the surface to enhance traction and prevent slip accidents during wet or oily conditions.
The product can be customized with logos, labeling, or color codes for quick system identification — for example, marking wastewater lines versus stormwater drains. Optional lockable designs also help prevent unauthorized access or vandalism.
Because SMC materials are non-conductive and non-magnetic, this manhole cover is ideal for areas with underground electrical or telecommunication lines. It also does not generate noise when driven over, a common nuisance with metallic covers in residential streets.
This cover is a smart, environmentally friendly option for municipal planners seeking a durable, low-maintenance, and safe access solution for sewer systems. It balances affordability with high performance, making it a top choice for modern urban development projects that require dependable utility access without compromising safety or aesthetics.
