Structural Cables, Rods & Bars


The Ronstan range of structural cables, rods and bars provides architects, engineers, designers and specialist contractors with locally manufactured structural tendons of export quality.  Our products are supported by application knowledge and experience gained over 65 years, an aggregation that ensures the selection of structural cables, bars or rods with properties matched perfectly to deliver the most efficient structural tendon solution for the project. 

Be it a glazed curtain wall, a tensioned fabric roof, an elegant suspension bridge or a cable net, Ronstan’s Cable, Rod and Bar Systems can be used as primary load carrying elements to deliver lightweight structures of unique depth and openness. Large spans can be created by balancing the need for reduced self-weight, with the application of minimalist and efficient high tensile cable tendons or structural rods and bars. This is lightweight tensile architecture and a Ronstan passion.

Product Features:

  • Open Spiral Strand, Full Locked Strand and wire rope constructions.
  • Stainless-Steel, Galvanized and Galfan® corrosion protection options.
  • Design, engineering and manufacture of bespoke Cable Nets, Cable Clamps and associated tensile structure hardware.
  • Structural rods and bars in S/S or Carbon Steel to 520N/mm² Min Yield Stress.
