because the two sides of the ground surfaces only resting on the supporting structure the two sides can be done in different colours so that the ground surfaces can be turned over at any time.
because the supporting structure is in aluminium and the ground surfaces are chipboard panels: they permit a prolonged use through time with relatively low costs of depreciation.
High Loading capacity
adding the low squares the loading capacity of the structure increases up to 1800 kg / sm.
Reaction to fire
