400mm GT-Truss is a four-point square truss with a 50 mm tube diameter and 2 mm wall thickness. It employs a conical connector system that forms a precise form-fit when joined with a copper hammer, delivering reliable traction while minimizing transport volume. The design emphasizes a high load capacity for its size and offers powder-coated finishes on request. The 1 m section weighs 7.5 kg, with load data provided for spans up to 16 m.
