The bar prestressing method is frequently used in the field of structural rehabilitation and strengthening. ANP-Systems GmbH offers complete systems for the prestressing of structures, including bar tendons with internal bond, without bond, and with external tendons.

In this context, smooth steel bars with cold-rolled fine threads are preferably used for the prestressing of very short tendons due to their low slip values.

Internally bonded bar tendons are mainly used in concrete, composite and masonry structures. In contrast, internally unbonded bar tendons and external bar tendons are typically applied as transverse prestressing, for bridge strengthening, in rehabilitation works, as connecting elements for steel structures and machinery, as well as for temporary tie-downs.
