Traffic signal backplates are designed to properly shield a traffic signal from  background obstructions. The backplate provides a dark silhouette that isolates the signal face from store lights, signs,  sunlight and other environmental conditions that tend to reduce the brilliance of the light indications. A study found that back- plating can cut the number of vehicle accident claims at intersections by nearly 15%.


  • Cored holes and stainless steel thread forming screws are provided in the die cast aluminum and polycarbonate traffic signals for quick, easy installation of backplates.
  • Aluminum backplates are fabricated from .063” 5052-H32  aluminum and are standardly primed and painted flat black on both sides. Aluminum backplating provides the strongest strength-weight ratio and is very  resistant to weather and corrosion in harsh environments.
  • Poly backplates are fabricated from  .125” high density polyethylene (HDPE) and are stand- ardly dull black on one side and semi-gloss black on the other side. Polyethylene backplating is very resistant to impacts and abrasions. It will also keep its strength and shape in extreme temperatures and severe weather conditions.
  • Available with 1”, 2” and 3” wide reflective tape installed in center or flush with outside edge. If reflective tape is required, the backplates will be fabricated from  ABS material.
