MULTIPROP Aluminium Slab Props - MP350 (1.95m to 3.5m). MULTIPROP frames – as shoring towers or load towers under tables. Compared with tubular steel slab props, the aluminium MULTIPROP carries significantly higher loads whilst, at the same time, has a very low dead weight. With different frame sizes, square or rectangular shoring towers can be optimally adapted to suit individual construction site conditions. The frames also serve as platform beams and side protection for working levels.
