The GD (Grand Duty) System meets the demand for a truss with a high load bearing capacity that lends itself to safe outdoor use, even at a free span of up to 20m at high load. Due to the square profile geometry and the complete diagonal bracing, the GD Truss exhibits the same rigidity in vertical and in horizontal direction and can thus absorb the forces of canvas coverings (awnings, advertising spaces, projection canvasses, etc). Made with the fast connection system and tested according to the Din 4113/VBG 70 specifications by the TuV.
