Interstate Grating Products

Bridge Decking

Bridge Decking is manufactured by cold-press riveting truss shaped recticuline bars to parallel rectangular bearing bars. The resulting product is an exceptionally durable heavy duty grating with superior stiffness and lateral stability. Bridge Decking is often the preferred heavy duty grating for concentrated or stress applications subject to impact and repetitive loads. Popular applications include bridge floors, highway inlets and airport trench drain covers. Bridge Decking Diagram
