Understanding 150 mm Gate Valves Functionality, Application, and Importance

Firstly, the primary function of a 500mm round drain cover is to provide access to the drainage system while preventing accidents. Urban areas are bustling with pedestrian and vehicular traffic, making safety a top concern. Round drain covers, due to their shape, can efficiently manage stress and load distribution. Unlike square or rectangular counterparts, which can be rotated in such a way that they fall into the drain, round covers cannot slip into the opening. This feature minimizes the risk of accidents, contributing to pedestrian safety and reducing liability for city planners and contractors.

In March and April 2012, Ajax, Ontario and Niagara Falls, Ontario^[25] had dozens of manhole covers stolen.
