Liner Plate

Liner PlateFull Length Corrugations & Lapped Joints for More Effective Stiffness & Ring Compression

CONTECH 2-flange Liner Plate provides optimum shaft stability and protection when constructing new utility tunnels, relining structures under highways and railroads and lining vertical shafts.

CONTECH 2-flange Liner Plate offers the highest continuous ring stiffness and high compression joint strength. 2-flange Liner Plate has effective stiffness that is more than twice that of the same gage (thickness) of 4-flange Liner Plate.

2-flange Liner Plate provides corrugations extending through the lapped longitudinal joint. When assembled, this liner functions as a corrugated pipe with continuous circumferential corrugations. The result is more effective corrugation performance for the highest stiffness and strength in the industry! Strength to handle the inconsistencies encountered on a regular basis. Extra safety factor when you need it most!
 

Benefits of CONTECH Liner Plate

  • Stiffest plate available - Usually does not require ring-beam stiffeners
  • Available in black (uncoated) or galvanized steel - Unsurpassed in strength and safety
     

Liner Plate for New Utility Tunnels and Enclosures

Liner Plate Utility TunnelDuring tunnel construction, slough-ins and other concentrated loads are unpredictable and can be catastrophic without adequate protection. Our sufficiently stiff tunnel Liner Plate functions as a safety zone for workers and equipment. The required amount of liner stiffness depends upon soils, tunnel size and construction methods.

Liner Plate for Vertical Shafts

Liner Plate Vertical ShaftVertical shafts vary in diameter from a few feet to 50+ feet, and frequently have depths exceeding 60 feet. Whether microtunneling, slip-lining, and installing tunnels, maintaining shaft integrity requires a dependable support system. Our Liner Plate is unsurpassed in strength and safety. Once tunneling is completed, the liner plate is often dismantled and reused.

Structural Plate for Rehabilitating Bridges and Large Culverts

Structural Plate Bridge RehabBridges 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.

 

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.

Potential Contribution: CONTECH Metal Pipe and Structures
  • Steel is the most recycled material in the world
  • Up to 80% recycled content

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.
