Kugel Knoten (spherical node). The KK-System was invented and developed in the 1940’s by the late Dr. Max Mengeringhausen and is universally recognized by industry and academia as the pioneering spacetruss system. Spherical solid nodes are drilled and tapped at varied angles to create any desired geometric form and round pipes with conical ends bolt axially between nodes to form spatial grids. Typical uses are very stiff double layer structures with amazing strength to weight ratios with spans up to 150m (500’).

Tube diameters and grid sizes vary according to strength, cladding and cost requirements. Optimal use of these materials provides impressive economy. The system is available in stainless steel or hot dip galvanized high grade steel. Finish options include powder and liquid paints, brushed or polished.
