- Introduction
The BBR FLAT is a bonded post-tensioning system using seven-wire prestressing strands and is particularly suitable for thin construction elements.
- Tendon Sizes
The standard tendons consist of 4 dia. 0,5” strands or alternatively of 4 dia. 0,6” strands.
- Post-tensioning System
The available anchorages are the active and passive anchorages.
- Introduction
The BBR CONA Single with monostrands is used where small post-tensioning units are required. For unbonded tendons the strand is coated with a special protective grease and encased in a plastic conduit. In case of bonded tendons, a corrugated metal or plastic sheath is installed, which is cement grouted after the stressing operations.
- Tendon Sizes
The standard tendons consist of one dia. 0,5” or 0,6” strand.
- Post-tensioning System
The available anchorages are the active and passive anchorages and the intermediate anchorages with continuous strand or with coupler sleeve.

- Introduction
The BBR CONA External is a further development of the CONA Compact system using seven-wire prestressing strands and is particularly suitable for unbonded external tendons.
- Tendon Sizes
The standard tendons are composed of 7, 12, 19, and 31 dia. 0,6” strands. Other tendon sizes can be obtained by omitting one or more strands in a standard tendon.
- Post-tensioning System
The available anchorages are the active and passive anchorages and the tendons can be executed as Basic Types (non-replaceable) or as Replaceable Types.
