Submersible Manhole Cover: A type of outdoor manhole cover designed for industrial and residential building areas. It can accommodate road aggregate, marble, and granite铺设. All products come with an accessible lid, suitable for drainage, ventilation, cable, and instrument wells. Comprised of a well frame and cover, it boasts strength and toughness far exceeding cast iron, making it ideal for environments with large spans and heavy loads, such as docks and airports.
Stainless Steel Invisible Manhole Covers, composed of a frame and a cover, feature a square indentation design on the cover. The cross-section can also be inverted trapezoidal, allowing for a tighter fit between the cover and the frame, improving the current shortcomings of manhole covers. The invisible covers only expose the four side frames at the ground surface, with the center sunken to a certain depth. The bottom of the indentation is designed to be curved, with reinforcing ribs on the indentation surface. The lightweight invisible covers have a steel plate structure and can be directly paved with tiles on the surface.
