Galvanized Post tension Flat duct(0.38mm-0.4mm thick)
 

Post tension Flat duct is used as a duct former for a variety of precast and cast-in-situ concrete work. The semi-rigid hot dipped galvanized metal duct is strong and durable for casting into concrete and is easily tied into position adjacent to reinforcing steel. Corrugated Duct can be used for post tensioning ducts and precast connections.

The concrete is placed around ducts or sheaths containing unstressed strands.

The anchor, duct and strand combination is referred to as a tendon. Once the concrete has gained sufficient strength, the tendons are progressively stressed against the concrete and locked off by special anchors. A bonded system fills the tendons with grout, whereas an unbonded system is where the tendons are not grouted.
