Fast, Easy, Low-Cost Installation with Proven Durability
Developed over 75 years ago, 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. Available in spans to 26 feet, MULTI-PLATE can be arranged and curved to make a variety of shapes including pipe, pipe-arch, horizontal and vertical ellipses, arches and underpasses.
Benefits of MULTI-PLATE systems:
- Buried Bridge Structure - Reduces maintenance costs and lowers life cycle costs as there are no bridge deck or joints at the deck/roadway interface.
- Modular Bridge System - Rapid installation results in reduced overall project costs, delays and detours.
- 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

 Our structural plate systems, including 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.
|
Our Structural Plate products can be used for fish passages and wildlife crossings. The ability of Structural Plate products to span the delineated area reduces the need for permitting and allows for quick installation.
|
 The many shapes and sizes of structural plate structures, 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.
|
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. Plate structures can also be utilized to extend and improve mine entrances, providing protection from falling rocks and debris.
|
Bridges and large culverts 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 Plase 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.
|
Plate structures allow highway agencies and municipalities to dramatically reduce construction time and traffic disruptions when replacing our nation’s aging infrastructure. Plate bridges are ideally suited for emergency bridge replacements.

SS Credit 1 – Site Selection, 1 Point
Intent – Avoid the development of inappropriate sites and reduce the environmental impact from the location of a building.
|
Potential Contribution: Bridge and Structures
- Long clear spans allow you to cross sensitive areas with little or no impact
- Maintain a 50-foot buffer on either side of the waterway
|
SS Credit 2 – Development Density and Community Connectivity, 2-5 Points
Intent – Channel development to urban areas with existing infrastructure, protect greenfields and preserve habitat and natural resources.
|
Potential Contribution: Bridges and Structures
-
Connect people and services over roads, under rail crossings and across streams
-
Shorten walking distance to basic services
-
Provide aesthetic solutions
|
SS Credit 4.1 – Alternative Transportation, Public Transportation Access, 1-6 Points
Intent – Reduce pollution and land development impacts from automobile use.
|
Potential contribution: Bridges and Structures
- Create bicycle trail connectivity - allowing alternative transportation mode
- Create shorter, safer pedestrian access to public transit
- Bring public transportation (i.e. railway) into a community with minimal impact to existing roads and grades
|
MR Credit 4 – Recycled Content, 1-2 Points
Intent – Increase the demand for building products that incorporate recycled content materials. The sum of post-consumer recycled content plus one-half of the pre-consumer content constitutes at least 10% (1 point) or 20% (2 points), based on cost, of the total value of the materials in the project.
|
MR Credit 5.1 – Regional Materials, 1-2 Points
Intent – Increase demand for building materials and products that are extracted and manufactured locally to a job site in hopes to reduce the environmental impact that would result from transporting these goods. Products manufactured, extracted and recycled within 500 miles of the project site for a minimum of 10% (1 point) or 20% (2 points), based on cost of the total materials value.
