Post-Tensioning Bars

High-strength bars for controlled prestressing and structural connections.

Post-tensioning bars are high-strength steel bars used to apply controlled prestressing forces and securely connect structural elements. Fully threaded and smooth configurations are available with compatible couplers, nuts, plates and corrosion-protection systems.

  • High tensile and load capacity
  • Controlled, adjustable prestressing
  • Easy extension using couplers
  • Fast installation and tensioning
  • Temporary or permanent use
  • Reliable structural load transfer
  • Corrosion-protection options
  • Complete accessory range
