The white mould in 10-cm thick aluminum enables to realize walls in small, medium and large buildings, ensuring a concrete pressure resistance of 60 kN/m2. Being anyway lighter than the steel mould, it features the same performance limits of the iron formwork and can be easily moved by hands, without the aid of cranes or other telescopic means. With the same section, the aluminum module moulds can be combined with the steel module ones by joining accessories such as the aligning clamp or pin and wedge.
