The BGR70 is a rectangular aluminum truss with dimensions of 690 mm height and 550 mm width. Constructed from EN AW 6082-T6 aluminum alloy with 80x80x5 mm main chords, it has a self-weight of 45 kg/m. This truss can achieve spans up to 45 meters while supporting a center point load of 750 kg. Its unique pre-camber system (0-4mm spacers) ensures zero deflection under load, making it ideal for motion and LED screen applications. The tool-less assembly system requires no tools for connection. Main cords measure 80x80 mm with 5 mm wall thickness, and bracing is 60x60x3.5 mm. The coupling system utilizes lugs (70x20 mm) and pins (18 mm).
