ポストテンション用ストランド

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.

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.

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.
