Fast, Easy, Low-Cost Installation with Proven Durability. MULTI-PLATE structures, consisting of field bolted galvanized steel plates, have a long history of strength, durability and economy. The structures offer high combined live and dead loads and are well-suited for deep cover applications. Developed over 75 years ago, MULTI-PLATE is available in spans to 26 feet, and can be arranged and curved to make a variety of shapes including pipe, pipe-arch, horizontal and vertical ellipses, arches and underpasses.

Designed “Site Specific” - Meets your site needs in full compliance with AASHTO, ASTM & AREMA design standards for highway and railway use. Easy Site Adaptability - Flexible layout options to fit within the right-of-way – curve the structure with a stream or adjust for vertical and horizontal clearance requirements Structural Plate for Mining Portals, Rail Tunnels and Conveyor Enclosures Our durable Plate Structures 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.
