High-Performance Composite Manhole Cover for Modern Infrastructure
Our composite manhole covers are designed to meet the diverse needs of today’s infrastructure projects, offering a durable, lightweight, and corrosion-resistant alternative to traditional metal covers. Manufactured from SMC (Sheet Molding Compound) or BMC (Bulk Molding Compound), these covers are engineered to perform in harsh environments while maintaining structural integrity over time.
Unlike cast iron or ductile iron covers, composite manhole covers do not rust, making them ideal for coastal areas, wastewater treatment systems, and chemical plants. Their lightweight design allows for easier handling during installation and maintenance, reducing the risk of worker injury and significantly lowering transportation and labor costs.
Each cover is built with an anti-slip surface for increased safety, especially in wet or high-traffic environments. Optional features such as watertight seals, bolted locking systems, or customized logos are available to meet specific project requirements. The covers can also be color-coded for easy utility identification (e.g., red for electricity, blue for water, green for telecom).
Our manhole covers comply with international standards such as EN124, offering load ratings ranging from A15 (pedestrian areas) to D400 (heavy-duty roadways). They are tested rigorously for load-bearing performance, impact resistance, and environmental durability, ensuring consistent performance even in extreme weather conditions.
One of the key advantages of our composite covers is their resistance to theft. Since they contain no scrap metal value, they deter unauthorized removal—a common issue in urban settings. Additionally, the non-conductive nature of composite material makes them safer around electrical and telecommunications infrastructure.
Environmental sustainability is another key benefit. Our production process generates low emissions, and the materials used are recyclable. This makes our composite covers an excellent choice for green building projects and environmentally conscious municipalities.
Available in a wide range of sizes and frame types (round, square, or rectangular), our covers are suitable for installation in roads, sidewalks, airports, ports, and industrial facilities. We also offer full OEM and ODM services, allowing for complete customization based on client needs.
With over 20 years of expertise in advanced composite technology, we are committed to delivering innovative, safe, and cost-effective manhole solutions that support modern urban development.
