19 feet steel grating drain manhole available
150 unit Available
The purpose of a steel grating drain manhole is to collect, protect, and control the flow of water while allowing easy access for maintenance.
Its main functions include:
Drainage: It collects rainwater or surface water and directs it into the drainage system, helping to prevent flooding and waterlogging.
Safety: The steel grating covers the opening, preventing people, vehicles, and large debris from falling into the manhole while still allowing water to pass through.
Debris Control: It blocks large objects, leaves, and waste from entering the drainage system, reducing the risk of blockages.
