Full 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
