Details

These sunken steel flow plates are purpose-built for one-way traffic control and are ideal for private car parks, business entrances and logistics yards. Designed to be embedded in-ground, the units allow vehicles to travel freely in one direction while presenting a raised barrier to those approaching from the reverse side.

Each unit features a counterbalance mechanism which lifts the plate back into its upright position immediately after being driven over. This functionality ensures continuous directional enforcement without the need for manual reset. These direction control plates are suitable for cars and HGVs (up to 7.5 tonnes), and are designed for areas where a heavy foundation may not already be in place.

In-ground design – Provides a permanent and flush finish for a professional install.
350mm x 220mm dimensions – Creates a 90mm high flow barrier.
Steel construction – Durable against vehicular impact and wear.
Silent action – Integrated noise buffers reduce operating noise.
Modular deployment – Multiple units installed together to span full access width.

Use of these traffic control plates should be paired with speed reduction ramps and clear warning signage to reduce wear and ensure maximum compliance.

FAQs

What are flow plates used for?
Flow plates are installed to allow one-way vehicle travel and physically block access from the opposite direction. They are commonly used in car parks, service roads, and exit lanes.

Are these suitable for HGVs?
Yes. These direction control plates are rated for cars and HGVs up to 7.5 tonnes.

Do they make noise?
No. These units are equipped with noise buffers to minimise sound, unlike cheaper models that produce loud clanging.
