BBR VT CONA CMB band post-tensioning system

The European assessed CONA® CMB post-tensioning system is a multi-strand technology for special external and also internal unbonded post-tensioned applications. The standard tendon configurations range from 1 to 16 strands. The unique system design offers a high level of corrosion protection and is widely used for the prestressing of wind towers but also for strengthening of railway and road bridges.

Key features

  • Standard tendon sizes from 1 up to 16 strands
  • Strands are configured in either 2 or 4 strand flat horizontal bands, stacked vertically up to 16 strands
  • Optimised for compacted strand – 15.2 mm diameter, 165 mm2 area, 1,820 MPa, Fpk = 300 kN
  • High level of corrosion protection ensured with transition tube and greased/waxed and HDPE sheathed monostrands.  An additional extruded smooth rectangular plastic sheath for extra durability is also available
  • Bands pre-cut and rolled onto a transportable drum for rapid deployment and tendon placement on-site
  • Ideal for strengthening of bridges, buildings and tank wrapping. Convenient flat band profile for transfer of transversal forces at deviator/saddle points
  • Restressable & exchangeable tendons perfectly suited for long-term inspection and maintenance
  • European Technical Assessment and CE marking
