The "LATTICE SLABS" consist of thin standard concrete basis reinforced by a wire net distributed over the whole surface and by three lattices. Their maximum width is of 120 cm, while the maximum length is that of the span to cover. They are lightened by two block rows set at intervals of 12 cm. These intervals and the lattices constitute the resistant ribs.
In correspondence to the ribs, the integrating steel reinforcement is set, sized for the loads and spans to cover.
They are very easy and rapid to lay and guarantee a uniform soffit that, with a mere shaving of the joints can be left "at sight".
They are VERY used particularly for the roofing of rooms requiring a high fire-retardant behaviour.
