LowPro 23/05 Traffic Plate

LowPro 23/05 HS20-44 Road Plate

Alternative to steel road plate trench covers

Our LowPro 23/05 Road Plate system that is made up of linking plates, meaning it’s suitable for 97,000lbs vehicles over a 48” trench (depending on the local DOT requirements). The LowPro 23/05 is a heavy-duty road plate – for smaller trench road plate options, see the LowPro 15/05 Road Plate.

Features of the LowPro 23/05 road plate

Reduction of Enviromental Impact

Oxford Plastics’ composite road plate is more eco-friendly than the traditional steel plate. Specifically, with steel plates contractors need to use cold patch as a ramp. This cold patch leaches oil when it rains, which then travels into storm drains and then local water bodies.

Our LowPro 23/05 traffic plates have ramped edges, meaning they can be anchored into place. They can also be transported with far smaller vehicles than steel plates, and installed without heavy lifting equipment.

EasiLift install with 2 crew members

Each section of these road plates weighs 145lbs, far lighter than a steel plate, and is easier to maneuver with the EasiLift handles. Using a team of 2 workers, rather than expensive heavy lifting equipment, the Road Plate can be carried and installed in minutes.

LowPro Anti-slide: Lateral Locks

Underneath the LowPro 23/05 are 2 sets of lateral locks: these locks drop into place when the road plate is installed on the trench. The locks sit within the trench on either side to prevent lateral movement.

LowPro Anti-slide Edges

The anti-slide technology, on the underside and edges of the 23/05 plastic road plate, is made from a soft, flexible, rubber material which grips the surface to reduce unwanted movement.

No noise pollution: LowPro Edges

The LowPro 23/05 road plate is currently used in residential areas, on roadways and utility sites partially because of its noise dampening edges. The patented LowPro feature reduces noise by absorbing sound, as the rubber-edges are far softer than steel – thus eliminating that harsh, loud clang when traffic drives over the top.

No Cold Patch

The installation time is reduced again when using the road plate: with its pinholes, drop pins, and LowPro Edges, there is no longer a need for a cold patch.


The LowPro 23/05 temporary road plate has a bespoke stillage to make handling, transportation and storage simpler.
