The PF5800 Sunken Flow Plate incorporates an inbuilt counterbalance action, ensuring that the PF5800 returns to the upright position after a vehicle has passed over it.
Constructed from heavy steel, the flow control plate is designed to encourage a mono-directional flow of traffic, as well as preventing vehicles from entering if they are travelling from the opposing direction.
They also have built in noise reduction buffers which prevent the common crashing metal sound in lesser models.
The PF5800 sunken traffic flow control plates are suitable for installations where a substantial foundation is not already present.
Not suitable for heavy goods vehicles (max 7.5 tonne)
We highly recommend the use of speed ramp and warning signage in conjunction with flow plates.
