These charts depict some of Concast's more common custom pedestrian-rated trench covers. Other sizes, traffic ratings, and designs are available upon request.  Refer to our replacement cover sizing worksheet which is available in both a pdf file as well as a downloadable Excel spreadsheet if you are considering getting custom covers for an existing trench run. The worksheet is a great communication and planning tool.

Concast has a simple part numbering convention for the custom covers: XWL-H(RW).

  • The "X" variable can be one of 4 different materials:
    • A=Aluminum
    • C=Concrete
    • F=Fibercrete ®
    • SG=Steel Galvanized (Pedestrian Rated)
    • HTSG=Steel Galvanized (Heavy Traffic Rated)
  • The "W" variable refers to cover width (spans the channel)
  • The "L" variable refers to cover length
  • The "H" variable refers to cover height
    • Drop the "H" for covers that are 1-1/4" high/thick
    • Also referred to as the "C" variable on the sizing chart.
  • The "RW" variable refers to rib width as it spans the cover.
    • Drop the "RW" is no rib is needed.
