Space. Simple form. Both mask a complexity inherent in tensile architecture. The structure in place, itself evidence of science and careful planning, stands to remind us of what can be achieved with the intelligent use of rods working together in tension. Be it a glazed curtain wall, a tensioned fabric roof, a simple yet elegant suspension bridge, or a cable net or grid structure, all can depend on rods as the primary load carrying elements. The results are structures of unique depth and openness, with large spans made possible by balancing the need for reduced self weight, with the application of minimalist and efficient high tensile rod tendons. This is lightweight tensile architecture and a Ronstan passion.


Description

A compact stainless rod system with optimal aesthetics, efficiency and performance.

Lengths/Span

Up to 3.6m (11.8’) for ø 6.35-12.7mm (0.250"-0.500")
Up to 6.0mm (19.7') for ø 15.88mm-31.75mm (0.626"-1.250") before joiners are required.

Rod Diameters

Up to 31.8mm (1.25”) as standard.

Specific Features

  • Minimalist design ensures compact neat details.
  • Easy adjustment of the rod from one end enables simple access and fast installation reducing time on site.
  • No exposed threads ensuring the 'sleekness' of the rod is carried through the entire system.
  • Clean polished stainless steel finish to withstand the harshest environments.
  • Good strength to weight ratio allows the mass of your structure to be kept low while minimising material and transport costs.
  • High corrosion resistance and low maintenance due to material choice decreases the life cycle cost of the structure.
  • Range of surface finishes - #7 Polished and passivated (standard option), #4 Satin. Others by request.
