Post-tensioning

Achieve a 100-year design life Bekaert’s uncoated or galvanized prestressing 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 prestressing 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.

Developing your business together

As a global leader in wire transformation and coating technologies, Bekaert has the ability to collaborate with clients and end users to develop unique solutions for innovative post tensioning technologies. We have experience in working with owners, design engineers, and construction contractors to reduce cost, increase safety, manage environmental impact, and extend the overall life cycle of your structure through product innovation.

Choose your options

Bekaert offers uncoated or class A  coated srands (Zinc, Bezinal®, Bezinal®3000) with high tensile strength up to 2260 Mpa (325 KSI). There is also 7-wire compacted strand available for optimal breaking load / diameter combinations.

Large-scale projects with ease

MTHL is the road bridge across the Mumbai Harbour connecting the island city of Mumbai and the mainland. 

To strengthen this 21.800 km of elevated highway, several thousand tons of strands from Bekaert were produced and used for post-tensioning work.

When completed, it would be the longest sea bridge in India.

Contributing to EU´s energy security

Extension of LNG regasification terminal in Poland

The project to expand the Polish terminal in Świnoujście is on the European list of Projects of Common Interest. This investment should improve the security and diversification of the natural gas supply in Europe. It also contributes to achieving the EU’s energy and climate goals.

We helped our customer VSL International Ltd. With prestressing operations of the structure by delivering 7-wire strands with advanced surface protection for this project.

Why choose our strands to reinforce LNG terminals?

  • High resistance to cryogenic exposure thanks to the supreme ductility of strands
  • Safe storage due to advanced surface treatment and protective packaging
  • Flexible partner with a global footprint
  • Your partner in the sustainability race
