Bar prestressing systems are frequently used in the rehabilitation and strengthening of structures. For these applications, ANP-Systems GmbH offers complete structural prestressing solutions, including bonded internal bar systems, unbonded systems, and external prestressing tendons.

Smooth steel bars with rolled fine threads are particularly preferred for prestressing very short tendons due to their minimal slip values.

Bonded internal bar tendons are primarily used in concrete, composite, and masonry structures. In contrast, unbonded internal bar tendons and external bar tendons are typically used for transverse prestressing, bridge strengthening, rehabilitation works, connection elements for steel structures and machinery, as well as temporary bracing applications.
