Why it works

Built for one-way enforcement

One-way control

A hinged flap lowers as a vehicle drives over it the right way, then springs back upright to deter wrong-way travel.

Bolt-down fixing

Fixes to existing hard-standing with 6 x M12 Rawl bolts per plate - no concrete excavation needed.

High-visibility yellow

Galvanised and powder-coated yellow finish keeps the plates clearly visible to approaching drivers.

Galvanised steel

Heavy duty steel construction, galvanised for corrosion resistance and a long service life.

Works in groups

Plates install side by side for full lane-width coverage across a road, yard or car park.
Overview

Vehicle One Way Flow Plates - Overview

This bolt-down flow plate enforces a single direction of travel across an existing road, yard or car park surface. Made from heavy duty steel, galvanised and powder-coated yellow, it fixes straight down to hard-standing with 6 x M12 bolts and installs in groups for full lane-width coverage.

Frequently asked questions

How do the flow plates enforce one-way traffic?

Each plate has a hinged flap that lowers flat as a vehicle drives over it in the permitted direction, then springs back upright. The raised flap makes it obvious - and physically awkward - to drive over the wrong way.

How are these plates fixed down?

Each plate bolts straight onto existing hard-standing with 6 x M12 Rawl bolts, so there's no concrete excavation to dig out - useful where a permanent ground submerged installation isn't practical.

Can HGVs drive over these plates?

No. This plate is rated to one tonne per axle and is not suitable for Heavy Goods Vehicles.

How many plates do I need across a lane?

Plates install side by side in groups to give full lane-width coverage - the number needed depends on the width of the lane or entrance on site.

Is there a permanent, ground submerged version?

Yes, we also stock a concrete-in ground submerged flow plate for sites where a bolt-down surface fixing isn't suitable.

What speed should vehicles travel over the plates?

A maximum of 5mph is advised, backed up with road signs to inform drivers and enforce the limit.

Should the plates be laid out in a straight line?

We recommend a staggered layout rather than a straight line - it spreads vehicle loading more evenly and reduces wear, though vehicles should still drive straight over each plate rather than turning on top of it.
