Space Frame Bolt Ball

Product description

Nodes starting from DIA90mm diameter (90,110,130,160,200,240,280,300,350...) shall be produced with C45 quality material in conformance with the GB standard, with hot forging in normalized condition and/or machining production techniques.
Required bolt connection holes shall be drilled and tapped with digitally controlled drilling machines.

Technical Advantages

  • Load applied to the nodes
  • Each node has up to 18 threaded holes as pin jointed connections
  • Gives greatest freedom in design
  • The nodes are balls, to give a free selection for the connection holes. The standard ball nodes have diameters from 49.5mm to 350mm. To connect several members to a relatively small node, the members will have to be conical at the ends.
