Construction Systems


  • load applied to the nodes
  • double- or multilayer
  • each node has up to 18 threaded holes as pin-joint connections
  • gives greatest freedom in design
  • double-layer structure
  • pin-jointed connection to the nodes
  • lower chord as ball node system
  • plane or vurved surfaces
  • average to wide-span structure
  • single-layer structure in triangular and/or trapezoidal surface geometry
  • bend resistant connection
  • i.g. for curved surfaces of average span structures
  • small to middle spans
  • cladding elements fixed directly on members
  • single-layer system in triangular surface geometry
  • pin-jointed connection to the nodes
  • curved surfaces of small to average span structures


  • single- or multi-layer structure
  • single bolted connections
  • sharp changes in inclination of roof i.e. shed
  • single layer structures, with high, slender sections
  • bending-stiff, pin-jointed connections
  • plan and vurved free-formed grid-shells with targe warpage
  • Single-layer grid shell structures, with high, slender sections.
  • Possibility of direct loading of the members without a secondary structure.
  • Semi-rigid, pre-stressed bolted connections invisible inside the sections.

  • Plane and curved free-formed grid-shells.
