Stainless steel invisible manhole cover

Stainless steel invisible manhole cover

The stainless steel concealed manhole cover is not an invisible manhole cover, but is not so obvious compared with the general manhole cover. It is composed of a well frame and a manhole cover. The manhole cover is designed as a square groove, and its profile can also be an inverted trapezoid, so that the fit between the manhole cover and the well frame can be made closer, and the shortage of the current manhole cover is improved. The invisible manhole cover only exposes the four sides of the frame on the ground surface, and the middle cover of the manhole cover is recessed. At a certain depth, the bottom of the concave surface is designed to be curved, and the concave surface is provided with reinforcing ribs. The new invisible manhole cover is made of steel plate structure, and the surface is directly paved and rotated. The manhole cover of the structure can be harmoniously integrated with the surrounding environment, and can be adapted according to different environments.
