Manhole Cover

A manhole cover is a detachable plate or lid used to cover ground apertures that allow access to sewer systems, underground utility tunnels, or maintenance chambers. Manhole covers are often constructed of strong, durable materials such cast iron, steel, or composites to withstand automobile traffic and deter unauthorised entrance. They frequently have a circular or rectangular shape and include lifting handles or hinges to make removal simple. Manhole coverings are essential for keeping subsurface infrastructure securely sealed from above and ensuring its performance.
