Structural Plate Installation Process

Long-lasting and virtually maintenance-free, Big R’s corrugated metal structures ship and install quickly and economically, with minimal equipment and labor requirements. Our technical teams will guide you through the complete project to ensure its success.

Reinforced concrete footings are cast over the prepared site.	The first arch segment is completely assembled on the ground.
Then, it is lifted into place and bolted to the footings on either side.	The segments bolt into base channels, integrated into the concrete.
Plates then attach individually to make up other arch segments.	If specified, reinforcement ribs are then added.
Layers of engineered backfill are added in sequential lifts.	Then the completed road surface is added with safety barriers.
