The Compression-Molded High Intensity Fiberglass Manhole Cover for Sewer sets a new standard for underground infrastructure safety and durability. Manufactured using advanced compression molding technology, this manhole cover combines high load-bearing capacity with corrosion resistance, addressing the limitations of cast iron and concrete alternatives—such as rust, theft risk, and heavy weight. Certified to meet EN 124:1994 standards, it ensures reliable performance in municipal sewer systems, industrial facilities, and urban road networks.
Exceptional Load Capacity
Engineered to withstand 12.5 tons (B125 class) of pressure, the cover safely supports passenger vehicles, commercial trucks, and construction equipment . The compression molding process creates a dense, uniform structure with minimal internal defects, outperforming hand-laminated alternatives in impact resistance and structural consistency .
Corrosion and Theft Resistance
Constructed from non-metallic fiberglass, the cover is impervious to rust, chemical corrosion from sewer gases, and saltwater exposure. Unlike cast iron covers, it has no scrap metal value, eliminating theft-related infrastructure damage and replacement costs.
Safety and Installation Efficiency
Equipped with a water-tight O-ring seal, the cover prevents stormwater infiltration and odor leakage from sewers . Its lightweight design (83kg per unit) simplifies handling during installation, reducing worker fatigue and requiring fewer personnel compared to concrete covers (typically 200kg+).
Municipal Sewer Systems
Installed in urban roads, residential neighborhoods, and public parks to provide secure access to underground pipelines, resisting heavy traffic and environmental stress.
Industrial Facilities
Used in factories, refineries, and wastewater treatment plants, where resistance to chemical corrosion and heavy machinery traffic is critical.
Transportation Hubs
Ideal for airports, ports, and railway stations, supporting high volumes of vehicle and pedestrian traffic while maintaining long-term structural integrity.
What certification standards does the cover meet?
It complies with EN 124 B125 and IS: 1726 Medium Duty standards, ensuring compatibility with global infrastructure regulations .
How often does the cover require maintenance?
The cover is maintenance-free under normal conditions. Annual inspections for debris buildup around the frame are recommended to preserve the seal.
Can it be locked to prevent unauthorized access?
Yes, optional bolt-on locking systems are available, providing security against tampering or accidental opening.
What is the warranty period?
The manufacturer offers a 10-year warranty against material defects and structural failure under proper use conditions.
