Post-tensioning strands

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, PTI and FIB standards. 

Superior corrosion resistance

Corrosion is one of the major cause of failure in post-tensioned structures. Galvanized post-tensioning strands by Bekaert combine excellent mechanical properties with advanced corrosion protection:

► 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.
