Lightweight SMC Manhole Cover with Anti-Skid Design and Chemical Resistance for Urban Infrastructure

The SMC Composite Manhole Cover represents a new generation of high-performance access solutions for modern infrastructure projects. Designed and manufactured using Sheet Molding Compound (SMC) reinforced with fiberglass, this manhole cover delivers exceptional load-bearing capacity, ensuring reliable operation even under the most demanding traffic conditions. Unlike traditional cast iron or concrete covers, which are prone to cracking, deformation, and rust, our composite design maintains long-term stability and safety while reducing maintenance costs.

Engineered according to EN124 standards, the cover is available in load classes from A15 to F900, making it suitable for applications ranging from pedestrian zones to heavy-duty highways and airport runways. The advanced cross-rib structure at the bottom enhances load distribution and prevents deformation under concentrated stress. This unique structural design ensures that the cover performs consistently across years of service, regardless of temperature variations or external impacts.

Our SMC composite material exhibits high tensile and flexural strength, which allows it to withstand repeated dynamic loads without fatigue. The non-conductive and non-sparking properties make it ideal for use in areas involving telecommunications, power distribution, and flammable materials. Each product undergoes a rigorous quality inspection process, including pressure, impact, and wear resistance tests, to ensure that every piece leaving the factory meets global safety standards.

Additionally, the lightweight nature of composite material makes transportation and installation easier, reducing the need for heavy lifting equipment. In large-scale municipal projects, this translates into faster installation cycles and lower labor costs. Combined with its long service life and resistance to corrosion, the total lifecycle cost is significantly lower than that of traditional materials.

From highways to industrial zones and ports, Elite’s high-strength composite manhole cover provides a durable, safe, and cost-effective solution for modern infrastructure needs.

Key Features & Advantages:

Security and safety are critical factors in public infrastructure management. Elite’s Anti-Theft Composite Manhole Cover is designed to address the growing concerns of cover theft, unauthorized access, and operational hazards. Unlike metal covers, which are often stolen for scrap value, our composite SMC covers have zero recycling value, eliminating the risk of theft entirely.

Beyond theft prevention, the manhole cover incorporates a built-in locking mechanism that ensures it remains firmly secured in place during use. This safety lock can be customized based on project requirements—options include bolt locks, magnetic locks, or stainless steel hinge locks, depending on the installation environment. The design not only prevents accidental displacement due to traffic vibration but also enhances pedestrian and vehicle safety.

The anti-slip surface texture provides added protection in wet or icy conditions, reducing the risk of accidents. All edges are chamfered to ensure a flush fit with the frame, minimizing noise and preventing dust or water infiltration. The non-conductive composite material also protects against electric shock risks, which is particularly beneficial in telecommunications and electrical networks.

Manufactured under ISO 9001 quality control, each manhole cover is subject to impact, torsion, and wear testing. Even after long-term exposure to UV light, saltwater, or chemical agents, it retains its original strength and appearance. With its combination of safety, stability, and smart locking design, Elite’s manhole cover ensures reliable performance for both urban and industrial projects.
