From Conception… to Completion

Our team will take care of every aspect of your bridge project.


When planning a bridge, be it for highway, railroad, logging, or mining, our patented COMPO-GIRDER® INVERTED CHANNEL BEAM will outperform conventional box or slab girders.

The main reasons for bridge contractors, precast manufacturers, design engineers, and developers choosing the COMPO-GIRDER® INVERTED CHANNEL BEAM are cost savings and versatility.

There are many other less obvious advantages such as ease of handling, full access to utilities, and a wide range of shapes and camber, all of which combine to achieve successful and timely project completion.

Economical and Versatile

  • Up to 24m (80’) normal application
  • Any load fatigue requirement
  • Unrestricted web height
  • Deck can be cantilevered to accommodate roadway, sidewalk, or curb
  • The COMPO-GIRDER® INVERTED CHANNEL BEAM can be lifted, rolled, slid or bunked at any one or two points along its length. This means easier handling at the yard, transportation, and launching site.
  • Pre-camber versatility, more pleasing profile and appearance

The Advantages of the COMP-GIRDER® over Prestressed Box Beams
