Traffic Flow Plates for Cars, surface mount, excl.fixings

Traffic flow plates are designed to control traffic flow by allowing vehicles to pass over them in just one direction. They provide a simple, low cost, unattended means, of preventing vehicles from entering a site, car park, etc. via a designated exit point, thus improving safety and reducing the likely-hood of accidents.
Ideal for use in one way systems, car parks, preventing residential areas turning into `Rat Runs`, etc. traffic flow plates are manufactured from heavy duty steel plate.

Our standard surface mount units feature sound deadening rubber bumpers, to significantly reduce the noise caused by their operation as vehicles pass over them (an essential feature when used close to residential properties). 
The units simply bolt to the road surface, making installation quick and easy. The rising flow restrictor plate allows vehicle wheels to pass over it in one direction only.  As soon as the vehicle has cleared the plate, the powerful spring mechanism ensures the immediate return of the restrictor plate to the raised position. 
The Standard Traffic Flow Plate is designed to effectively and safely control the flow of vehicles such as the family saloon car, small vans, etc. and features a 100mm high - flow restrictor flap

Flow Plates for other vehicles

For HGVs, larger vans and 4x4s, the standard flow plate will not provide adequate deterrence to travelling over the plate in the wrong direction, which is why we offer alternative flowplates to cope with these situations


Our HGV Traffic Flow-Plate is designed to withstand a much heavier axle weight than the standard plate and features a higher Flow Restrictor Flap (203mm). These units can however not be used in locations where cars or vans may travel over them as the sprung flap could cause damage to the underside of the vehicle passing over them.

see our -  HGV Traffic Flow Plates   for further details.


Our Multi-Purpose Traffic Flow Plate is designed to be used in locations where a mixture of vehicle types will pass over the installed plates. These units are based on the HGV plate chassis to withstand the weight of heavy vehicles such as HGVs, but are fitted with a reduced height Restrictor Flap (115mm) to accommodate cars, vans, etc.

see our -  Multi-Purpose Traffic Flow Plates  for further details.


Choice of Fixings (fixings must be ordered separately);

Because the surface to which the Surface Mount Flow Plates are to be installed will vary according to location, we offer a choice of optional fixing packs to suit concrete or asphalt surfaces as required and which must be ordered separately.


You will need to order one Concrete or Asphalt fixing pack for each Flow Plate - see below;

for each Standard flow Plate, you will need 1 x 6 fixing pack

for each HGV or Multi-Purpose Flow Plate, you will need 1 x 8 fixing pack.



  • All our Flow Plates are made in the UK to the original Flow Plate design, other flow plates imported to the UK are often made of thinner material and less resilient to the day to day wear and tear placed upon them. 
  • Although Flow Plates are a stock item, at times of high demand, manufacturing and restocking could take up to 1-2 weeks, please speak to a member of our team to check current lead-time if you have an urgent requirement.
  • Speed restrictor bumps can be installed to reduce the speed of traffic approaching the flow plates and suitable speed restriction signs may also be displayed.
