Revolutionizing tunnel liner plate construction methods and application ranges.
THE EDGE Four-Flange Structural Liner is the latest innovation from AIL’s research and development teams.
Flanged seams instead of conventional corrugated metal plate overlaps
Simply put, THE EDGE is just the integration of bolting flanges to all four sides of our Super-Cor corrugated steel plate sections. However, it has been revolutionizing traditional shaft and tunnel liner plate construction methods and application ranges for the civil and mining sectors.
Ten times stiffer, five times stronger than traditional tunnel liner plate
The flanges add significant strength to the steel plates, buried arch bridges, deep coil tunnels and other structures, often reducing the need for reinforcement ribs on applications like large tunnels, overpasses or support structures.
Build corrugated metal structures from one side — faster, safer and more accurately
THE EDGE Four-Flange Structural Liner allows for better fitting/assembly of plates and that means smaller crews and a lower installed cost. The flanges can be built on the outside or the inside of a structure, so assembly work can all be carried out from one side when access is restrictive. Underground tunnels, support structures and shaft liners can be completely built from the inside. Corrugated metal structures over functioning rail lines, conveyors or streams can be built from the outside.
Custom-curved or leak-resistant corrugated steel structures
Optional custom-flanged plates can be incorporated to facilitate curved structures, and gaskets can be added to the flange seams to provide leak-resistance for a wide array of corrugated metal applications.
Recommended for tunnels, shafts and other mining applications
THE EDGE Four-Flange Structural Liner is recommended for mine shafts, vent raises, escape-ways, portals, canopies, ground support structures, relining of existing structures, road or rail overpasses, heavy haul road crossings, stockpile tunnels, storage structures and protection structures.
Recommended for bridge construction and other transportation applications
Tunnels, vertical shaft liners for CSO or commuter rail projects, road or rail overpasses, grade separations, bridges, relines of existing structures, ground support and control, protection structures, storage structures and water intake structures.
Discover the many benefits of buried arch bridges
Structural plate bridges or buried arch bridges offer many advantages over concrete equivalents and traditional site-built beam bridges, truss bridges or concrete drainage pipes.
