6 Multistrand PT slab wedge plate systems

The multistrand PT slab wedge plate systems is normally adopted for bonded tendon.

The strands are individually gripped in one flat anchor head unit and tramsmits their prestressing forces by means of flat type anchor plate casting unit.

The strands are stressed individually by means of a mono strand jack.

The strands are contained in one flat duct which is made of corrugated galvanized or non-galvanized metal.

To ensure corrosion protection and to give adequate bond strength, the tendons are filled with suitable cement grout mix after complete stressing of the strands.
