Road Plates | Trench Shoring Cages

The road plates made of steel are utilized by nearly every construction and utility company around the world for covering trenches, shielding roadways or used in a vertical shoring applications such as plate and H-Beam. Nearly every utility or road construction project requires steel plates or mats to temporarily cover the open excavation and allow for vehicle and pedestrian traffic over the trenches.

These plates are an essential item for a safe site. Their installation must not present a hazard to pedestrians, cyclists nor motorcyclists. Road plates may be required to extend across excavations in order to open the roadway to traffic during traffic sensitive periods, at night or at weekends. Their use must be authorized by a suitably qualified expert who will decide on the dimensions and thickness of the plate to be used. The thickness will depend on the width of the trench to be covered and the type of traffic expected to use them. The sides of any trench must be satisfactory shored up beneath the road plates and they must be firmly secured to the road surface.

Typical road plate dimensions are:

  • 1”, 1 ¼”, or 1 ½” Thick
  • 48”, 60”, or 72” Wide
  • 96”, 120”, or 144” Long

Custom fabricated plates can be made to meet any specified job requirement and apply custom fabrication to your road plates, such as:

  • Lift Holes and Slots in Varied Dimensions
  • Welding used to engrave company name, job name, and numbers
  • Specialty dimensions made to fit
  • Specially Requested Grades of Steel

These plates must be either sink into the surface or suitable asphalt material used to provide a ramp to the plate level. Where ramps are used, and there is a notable change in the road level, suitable ramp notice signs should be in place. The edges of the road plates next to the excavation should be enclosed to stop falls.

Road plates can be coated with a special epoxy treatment to make the road plate safe and anti-skid. The traction of road plates throughout wet, rainy and snowy weather, was an evident growing cause for concern throughout the construction and utility industries.

With the passing of time, many companies and contractors generated many procedures for making road plates anti-skid. Some companies use sandblasting technologies to treat their road plates. Other companies apply a non-slip grip tape to the road plate surface to counter slippery conditions of the plate and provide further protection from harm for work crews, pedestrians, and vehicles.

An alternative to the traditional steel road plate is the composite road plate. Made of a fiberglass, these composite road plates are lightweight, durable and capable of withstanding weights of 96800 pounds. The lightweight composition of these road plates means that they can all be easily positioned, eliminating the need for machinery normally needed to place traditional steel road plates.
