Pedestrian Use Square Type Water Supply Manhole Cover, A15 Clear Open 500X500

Key Advantages
• Medium Square Opening: The 500×500mm opening strikes a balance between inspection accessibility and compact installation, compatible with standard inspection wells for municipal water supply mains and secondary water supply systems.
• 1.5-Ton Load Capacity: Optimized for light-load scenarios such as pedestrian zones, non-motorized lanes, and green belts in compliance with the A15 standard, balancing safety and cost-effectiveness.
• Food-Grade Environmentally Friendly Material: Free of heavy metals, non-toxic and odorless; the material does not chemically react with drinking water or release harmful substances, protecting water supply quality from the source.
• Tight Sealing and Pollution Prevention: The precision-fit cover and base effectively prevent surface sewage, rainwater backflow, and foreign matter intrusion, ensuring clean water quality in the pipeline network.
• Lightweight and High-Strength Design: Weighing approximately one-third of an equivalent cast iron cover, it allows water utility personnel to operate single-handedly, improving maintenance response speed and operational efficiency.
• Weather-Resistant and Maintenance-Free: Resistant to aging, UV rays, acids, alkalis, and soil corrosion; color and appearance remain stable over long-term use with no coating or maintenance required.

Applicable Scenarios:

Municipal water supply main pipeline inspection wells, secondary booster pump stations, residential community water supply main inspection wells, public building water supply system inspection facilities, and irrigation system maintenance facilities.
