Lattice girders^GT for half slabs

Composition

Lattice girders^GT are three-dimensional, industrially prefabricated reinforcing elements. They consist of an upper chord, two lower chords, and continuous diagonal truss wires. Truss wires are connected to the chords by means of electric resistance welding. The lattice girder^GT for half slabs is kept in stock and, therefore, is available at short notice.
