A manhole cover is a removable lid or plate that is used to provide access to underground utility or maintenance structures, such as sewers, drainage systems, or electrical or telecommunication infrastructure. Manhole covers are typically made of durable materials like cast iron, steel, or composite materials, which can withstand the weight of vehicles and pedestrian traffic.

The primary function of a manhole cover is to secure the opening of a manhole while allowing authorized personnel to enter and perform maintenance or inspections. They are designed to be heavy and sturdy, preventing accidental access by unauthorized individuals and ensuring the safety of pedestrians and vehicles.

Manhole covers are often round or square in shape and are installed flush with the surrounding pavement or ground level. They are designed to withstand heavy loads and provide a secure seal to prevent debris, water, and other materials from entering the underground structure.Their design and durability contribute to the efficient and safe operation of utility systems in urban environments.
