Custom Cover Photo Album

Custom Covers Concast offers special covers to be used for a variety of applications including replacement covers for existing trench runs. They are especially useful for poured-in-place trench systems. The charts below lists some of the common sizes for pedestrian rated covers; but they can also be designed to meet AASHTO H-10, H-20, and H-40 Traffic Ratings for road crossing applications. Covers are available in Fibercrete®, concrete, aluminum, and galvanized steel. The concrete based covers can be miter/angle cut, colored, and stamped; Fibercrete® covers are light-weight and are under 100 pounds. Concrete covers utilize threaded inserts for machine assisted lifting.  All of them are high strength. Cover layout drawings are available upon request.   *Trench Cover Sizing Chart (PDF Format) *Trench Cover Sizing Chart (Excel Format)

These charts depict some of Concast's more common custom pedestrian-rated trench covers. Other sizes, traffic ratings, and designs are available upon request.  Please be sure to check out 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
• 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.
