AluGD is a formwork system that was designed to allow the realization of traditional slabs with joists and hollow clay blocks; it is also used for concrete slabs: - up to 45cm module 100x200cm - up to 70cm module 100x100cm. Standard module = 2,00m x 1,00m. Wheelbase girder grid = 113 mm. Component weight < 25kg The support heads in the AluGD system are different: fixed, dropping, for compensations and lowered beams. The props used can be: - CEP 10-20. - AluCP props. The AluGD modules are of these types: - Standard - For longitudinal compensations - For transversal compensations To facilitate assembly they are differentiated by colour. The 27 mm covering panels are made of wood and are nailed to the girder grid.
