Embedded design for seamless integration: The stainless steel inspection chamber cover uses an embedded design with the same material as the surrounding ground. This allows asphalt or lawns to be laid right over it, providing strong invisibility and harmony with the environment, while enhancing overall aesthetics. Durable stainless steel construction: Built from thick stainless steel, the cover offers a strength structure that maintains stability and resists deformation. A minimized gap between the frame and the cover improves road traffic performance and visual appeal. Resistant to harsh conditions: Designed for longterm outdoor use, the embedded manhole lid delivers safety and durability. It resists erosion from atmosphere, acid, alkali, and salt, making it suitable for varied harsh environments. Convenient maintenance features: A pull hole on the edge and an integrated handle enable easy lifting and maintenance. The design is lightweight—approximately twothirds the weight of cast iron—which simplifies installation and inspection. Use scenarios Urban streets and pedestrian areas: Flushinslot installation where the ground surface is extended with asphalt or paving, preserving aesthetics while providing reliable access for maintenance. Parking lots and landscaped zones: Embedded coverage that blends with grass edges or asphalt, allowing seamless integration into landscaped or paved areas without compromising accessibility. Coastal, industrial, or chemicalexposure sites: Durable stainless steel construction and corrosion resistance ensure reliable performance in harsh outdoor conditions while maintaining ease of service.
