One-way flow plates
Control traffic in and out where traffic must travel in one direction only
Our one-way flow plate solves the problem of controlling traffic in and out of car parks or around sites where traffic must travel in one direction only. Installed in groups, typically six per 3 m wide roadway, the robust flow plates are pushed down as a vehicle passes over in the correct direction, then the weighted plates flip back up after the vehicle has passed. However, if a vehicle attempts to pass in the wrong direction, the flow plates do not deflect out of the way. One-way flow plates are therefore extremely effective at enforcing traffic flows.
One-way flow plates are manufactured from steel, galvanised to provide protection from corrosion, and finished with a tough, high-visibility yellow paint. A heavy-duty rubber buffer on the reverse of the plate minimises noise.
Sets of one-way flow plates are installed by casting in concrete and we recommend that they are used in conjunction with speed ramps and warning signs. They are not suitable for use where HGVs are present.
