Steel bridge with a Fiberglass bridge deck

  • robust, extremely durable, immune to water ingress, de-icing materials and superior to concrete decks .
  • concrete weighs 5x more than Fiberglass
  • Fiberglass allows pre-assembly on site, then install using lighter cranes than concrete


FRP Pedestrian Bridge Decks

lightweight FRP pedestrian bridge decklightweight FRP pedestrian bridge deck

  • since 1994 manufacturing fiberglass composite bridge decks 
  • lightweight weighing 5 to 11 pounds per square foot
  • FRP robust and durable with over 60 years of durability in chemical corrosive service without degradation
  • FRP bridge deck is immune to corrosion and water ingress with a longer life and very low maintenance costs
  • design and manufactured as prefabricated panels in any depth, shape, skew, camber, cross fall, conduits, etc.
  • modular in width and length
  • embedded mechanical connections for long term durabilty
  • scuppers, curbs, expansion joints, railing post attachments, manholes, access ports, etc.
  • non slip wearing surface for pedestrian, snow plows, ATV, Snowmobiles
  • Colors available
  • Design to Canadian Highway Bridge Design Code or AASHTO Pedestrian Bridge Specifications
  • Design Service Life 100+ years 
  • Light weight panels easy to load, handle, install for accelerated or rapid construction
  • Deck thickness depends on loads and support structure but a table chart for discussion is noted
