About us

3D NEXUM GmbH, based in Zug, develops innovative joining technology for metal construction and façade construction. Its core product is the 3D coupling, a connecting element that enables the assembly of aluminium profiles and components without special tools and without specialised training. The company supports customers from engineering and the design of custom connecting elements through pilot projects to series production, and supplies matching assembly tooling in the form of four-piece sets made of stainless steel tube (CNS 8 × 2 mm). The systems were tested by Lucerne University of Applied Sciences: for air and driving-rain tightness up to 1200 Pa (SN EN 12152/12154) as well as for tensile resistance according to SN EN 16758. The 3D coupling is compatible with profiles from Gutmann, Wicona, Heroal, Raico, Schüco, Reynaers and Euro-Nut systems. Fields of application include façade construction, metal construction, furniture and wood construction, building services, the construction industry, automotive and aerospace, as well as protection against vandalism.
