Contech Aluminum Structural Plate Bridges
ALUMINUM STRUCTURAL PLATE BRIDGES
ALUMINUM STRUCTURAL PLATE BRIDGES
Lightweight for Easy Installation. Aluminum Structural Plate provides all the advantages of steel MULTI-PLATE and its light weight adds to the ease of installation compared to other structures. It weighs 1/50 as much as reinforced concrete pipe, reducing assembly and equipment costs and allowing for easy handling of long preassembled structures.
Aluminum Structural Plate offers designers and DOT’s unparalleled durability, design strength and speed of construction. The combination of lightweight material and variety of shapes and sizes also makes this product excellent in reline or rehabilitation applications.
INFORMATION
MATERIAL
Plates are fabricated from an aluminum allow with material properties that conform to AASHTO M219 and ASTM B 209 specifications.
BURIED BRIDGE STRUCTURE
Reduces maintenance costs and lowers life cycle costs as there are no bridge deck or joints at the deck/roadway interface.
BRAND
Contech
PRODUCT TYPE
Bridge
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.
DETAILS
Aluminum structural plate’s corrugation pattern has a 9” pitch and a 2 ½” depth. The corrugations are at right angles to the length of the structure.
BOLTS AND NUTS
Hot-dipped galvanized, specially heat-treated ¾” diameter steel bolts, meeting ASTM A 307 specifications, are used to assemble structural plate sections. The underside of the bolt head is uniformly rounded and does not require special positioning. In addition, the underside of the bolt head is ribbed to prevent bolt rotation while tightening. Unlike conventional bolts, once the nut is finger tight, final tightening can usually be accomplished by one worker.
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.
DIMENSIONS
-Thickness : Nominal plate thicknesses are available from 0.125” to 0.250” (See Table 12).
-Widths : All standard plates have a net width of 4’-6” centers provide a standard 5.33 bolts per foot of longitudinal seam in two parallel rows at 1 ¾ centers. The outside crests of the end corrugations are punched for circumferential seam holes on centers of 9.625” (or 3 pi).
-Lengths : Individual circumferential plate lengths are noted in terms of N (N = 9.625” or 9 5 /8” or 3 pi). Standard plates are fabricated in seven net covering lengths :
- 8N (77.00”), 9N (86.63”)
- 10N (96.25”), 11N (105.88”)
- 12N (115.50”(, 13N (125.13”) and 14N (134.75”)
The N nomenclature translates circumference directly into nominal diameter in inches. For example, two 10N plates give a diameter of 60” (2 x 10N x 3 pi); three 12N plates = 108” (3 x 12N x 3 pi), etc. Various plates lengths structure shape and size.

APPLICATIONS
PLATE STRUCTURES FOR RUNWAY EXTENSIONS
Our Structural Plate products provide strength, durability and construction speed when extending runways and taxiways.
PLATE BRIDGES FOR BRIDGE REPLACEMENT
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.
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 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 REHABILITATING BRIDGES
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 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.
