The Topdeck System, a two story aluminium system, was introduced in 1983. The strong yet lightweight profiles allow for a construction that is extremely stable without securing it to the floor. There are many accessories available in conjunction with the basic construction to create various design possibilities. The flat surface of the structure provides different cladding options with panels. The characteristic of the Topdeck system is the thickness of the profiles and the 10.5 mm groove. The groove width and grid design of the Topdeck makes it fully compatible with the Standard System. Even all the other Alusett profiles can be used in conjunction with the Topdeck.
