The Pittini Group was the first to offer electrowelded lattice girders to the building sector, thus significantly contributing to the industrialisation of modern construction.
The electro-welded lattice girders manufactured by the Pittini Group, which are well known all over Europe owing to their range, high quality and expert technical support, are used to make floor lattice girder beams (for clay-cement mix or concrete floors), lattice girder slabs (bridge decks, large monolithic or lightened floors) and double slabs (reinforced concrete cross walls in seismic zones, retaining walls, curtain walls, etc.)
These products have become more and more widespread owing to safe and fast on-site laying and suppression of props when grouting. That is why they are largely used for bridge decks.
Recent studies at national and European levels have reported the effective use of lattice girder slabs for decks in steel constructions, both in terms of ductility and in fire resistance, improving performance compared with traditional solutions at the same weight. The use of double lattice girder slabs for seismic walls in steel constructions is a valuable and innovative solution for industrial buildings.
