Road Plates are an essential item for a safe site. Marwood Group Ltd only supply plates made from a suitable material and with an appropriate skid resistant surface where necessary. Their installation must not present a hazard to pedestrians, cyclists or motorcyclists.

Road Plates may be required to bridge excavations in order to open the carriageway to traffic, e.g. during traffic sensitive periods, at night or at weekends. Their use must be authorised by a suitably qualified supervisor who will decide on the size and thickness of the plate to be used. The thickness will depend on the width of excavation to be spanned and the type of traffic expected to use them.*

The sides of any excavations must be suitably supported beneath the road plates and they must be rigidly secured to the road surface. Road plates must be either sunk into the surface or suitable bitumastic material used to provide a ramp to the plate level. Where ramps are present, and there is a significant change in the road level, appropriate ramp warning signs should be in place.

The edges of the road plates adjacent to the excavation should be fenced to prevent falls.

Marwood Group Ltd does not provide any data on loading and deflection the plate can take and withstand. It is the customer’s responsibility to ensure the stability of this product, especially to support the load when bridging a void. If in doubt, customers must contact their structural engineers before hiring/buying the plate

*As a guide: Pedestrian usage = 13mm thickness, Vehicular usage = 19/20mm or 25mm thickness.
  • Flat steel plates supplied complete with lifting eyes cut into 4 corners

Some plates may or may not have centre lift, please check with your local depot when placing an order.
