Product Overview
Our standard traffic control plates provide an effective traffic control solution. The counterbalance action allows only vehicles going in the correct direction to pass over them, creating a one way traffic flow.
Our standard design is available in 305mm (12”) and 610mm (24”) width sizes. For sinking into roadways to a depth of approximately 305mm (12”), drainage is required.
We recommend our SB.22 75mm speed ramp be used in conjunction with the sunken flow plates, as speed is advised to be reduced to 5mph on approach.
