Standard truss exhibition stands.

The most commonly used format of exhibition stands are standard stage trusses with a side width of 290 mm. The reason for their popularity is their wide availability in equipment rentals, as well as their classic "club" appearance. Trusses in the 290 format are available in two versions - described on a triangular plan (so-called trisystem) and a rectangle (quadrosystem). The advantage of the first is their lower weight and lower purchase cost - hence their popularity at fairs, where ease of transport goes hand in hand with minimal load requirements. Quadro trusses have their place on the stage, where the maximum spans of beams without support are large, as are the loads (from roofs, lighting and sound systems). AluPro exhibition stands in the TS290 system are equipped with flat bar-screw connections "F". Their advantage is full symmetry and ease of assembly. No atypical elements that, if lost in transport, are difficult to buy in delegation conditions.
