High Quality Sewer Drain Lid Manhole Covers

Manhole cover is a removable plate that is used to cover openings in the streets or sidewalks, allowing access to underground utility tunnels or maintenance shafts. These covers are typically made of cast iron, although other materials such as concrete or composite materials may also be used.   Manhole covers are designed to be heavy and durable to withstand the weight of vehicles passing over them. They are usually round in shape, although some may be square or rectangular. The covers are typically stamped with the name or logo of the city or utility company responsible for their maintenance.   The main purpose of manhole covers is to provide access for maintenance and inspection of underground infrastructure such as sewer lines, storm drains, electrical cables, or telecommunications systems. They also serve as a safety measure to prevent accidents or injuries from falling into open manholes.
