Freyssibar Prestressing System

Developed by Freyssinet, Freyssibar is a prestressing system which comprises of a wide range of fully threaded bar and complementary anchoring, coupling and extension devices. It is used for post-tensioned cables and prestressed ground anchors and can also be transferred to any application involving temporary or permanent tie rods.

Freyssibar bars are often used to introduce prestress into existing areas with high stress concentrations or subject to bursting forces. This could include column heads, bridge deck diaphragms, and anchorage regions. Freyssibar can provide a useful increase in load carrying capacity or act as a remedial solution for existing over-stressed sections and can also be used as an alternative to plate bonding.
