APPLICATIONS
STRUCTURAL PLATE FOR STORAGE STRUCTURES AND AMMO BUNKERS
Consisting of field bolted galvanized steel plates; MULTI-PLATE has a long history of strength, durability and economy. It is arranged and curved to make a variety of shapes, including round, pipe-arch, arch, and ellipse (horizontal and vertical). BridgeCor's advanced profile and variety of shapes is an ideal solution as well.
STRUCTURAL PLATE FOR GRADE SEPARATION
Our structural plate systems, including BridgeCor, MULTI-PLATE, Aluminum Structural Plate and SUPER-SPAN, are used frequently throughout the nation's infrastructure because of its light weight, durability and ease of installation. Structures can be pre-assembled on-site and lifted into place or assembled in place without the need for heavy or specialized equipment.
STRUCTURAL PLATE FOR PEDESTRIAN AND RECREATION TRAFFIC LOADS
The many shapes and sizes of structural plate structures, BridgeCor, MULTI-PLATE, Aluminum Structural Plate and SUPER-SPAN, as well as their low cost and ease of installation, make them a mainstay for pedestrian and golf course bridges, overpasses, underpasses, and tunnels.
STRUCTURAL PLATE FOR REHABILITATING BRIDGES
Bridges can be relined by erecting our plate structures inside existing structures. Or, the new plate structure can be erected outside and threaded into existing openings. Our Plate Structures, including Two-Flange Liner Plate, are delivered to the job site unassembled. The plates and ribs are easily bolted together to form various shapes: round, vertical and horizontal ellipse, pipe-arch, underpass and arch.
STRUCTURAL PLATE FOR MINING PORTALS, RAIL TUNNELS AND CONVEYOR ENCLOSURES
Our durable Structural Plate can meet heavy duty demands for industrial or mining applications. MULTI-PLATE round arch shapes are the most widely used structures for aggregate tunnels.

Special features such as hopper openings, conveyor supports, bulkheads, escape laterals and elbows to accommodate grade changes and alignment are readily integrated. Plate structures can also be utilized to extend and improve mine entrances, providing protection from falling rocks and debris.
