Post-tensioning strands

Achieve a 100-year design life Bekaert’s uncoated or galvanized post-tensioning strands. These steel seven wire strands are the ideal component for large post-tensioned concrete structures such as bridges, parking structures and high-rise buildings. Bekaert post-tensioning strands are produced in compliance with ASTM, EN, ISO, PTI and FIB standards.

Superior corrosion resistance

Corrosion is one of the major cause of failure in post-tensioned structures. Galvanized and zinc-aluminium alloyed coatings ( Bezinal®, Bezinal®3000 ) post-tensioning strands by Bekaert combine excellent mechanical properties with advanced corrosion protection. Moreover all strands can be HDPE sheathed.

  • Chloride Tolerance
    The chloride tolerance of galvanized reinforcement is >10x higher than black steel delaying the onset of steel corrosion significantly.
  • Carbonation Tolerance
    The pH around black steel can drop to <11.5 su causing it to depassivate. Galvanized coatings can maintain passivation, by keeping the pH down to 8 su.
