    Technical Specification 

    Gable roof design has become the standard in aluminum truss temporary roof structures throughout the world. Roof 2 system comes in three different size variations covering small to big size events. It is a very popular roof structure thanks to its variability, strength and decent size measures. The main grid is assembled on the ground and then lifted up thanks to the employment of Tower 1 elevation systems.

     The main rectangular grid of Roof 2 is made of FT44 trusses while the front and rear rafters come from FT34 truss line and the inside rafters are made by FT33 truss segments. The gable of the roof is created by the FT34 rafters and specifically designed corners for strong and secure roof structure attachment. Three inside FT33 rafters are connected to the main grid and top beam through clamps. The rafters are spaced 2.5 m apart from each other in order to create a sufficient support for the top canopy placement eliminating water pockets. 

     Roof 2 for stage size 12 x 10 m (39.4 ft x 32.8 ft) can cover wide range of events while still maintaining great loading characteristics. Front and rear main beams of the grid can carry load up to 120 kg/m (81 lb/ft) and at the same time the side truss beams can handle imposed load of max. 35 kg/m (23.5 lb/ft). In total the max. loading capacity of the roof comes up  to 3500 kg (7716 lb). The operational wind limit for using the roof system with the side canopies on all three sides is 20 m/s (45 mph).

    Wind Management

    Wind resistence is calculated with 3 side mesh canopies applied to the structure (2 side canopies and one rear canopy). The three roof walls carrying canopies must be secured by guy wire cross bracing at all times as well as the top grid horizontal ceiling. 

    Side walls guy wires min. loading capacity - 2900 kg (6393 lb)

    Rear walls guy wires min. loading capacity - 3400 kg (7496 lb)

    Roof ceiling guy wires min. loading capacity - 1700 kg (3748 lb)

    Please note that tension capacity of guy wires needs to be higher than required min. loading capacity.


    In service max. allowed windspeed - 20 m/s - 72 km/h - 45 mph



    Option 1 - 3000 kg / 6614 lb ballast underneath each tower base = total of 12 000 kg / 26,455 lb ballast necessary


    Canopy and Side Walls

    Top canopy is available standardly in silver grey and black color. The material used is SIO-LINE B 8000 with weight of 630 g/m2.

    The side walls are covered by air permeable mesh canopies in black.
