It is engineered to withstand both bending and axial loads, making it especially useful in tunneling and concrete reinforcement applications. These girders offer a high strength yet lightweight solution, serving as both a framework and reinforcement for shotcrete in tunnels or as stiffening elements in precast concrete slabs
Lattice girders were developed for the special demands of mining and tunnel construction. Lattice girders are completely integrated into the shotcrete shell. Porous zones, respectively spray shadows are avoided.
Settling of the surrounding ground is reduced and the water tightness of the shotcrete shell is improved significantly.
