Stainless prestressing steel grades
Ultimate solution for prestressed concrete
structures subject to chloride exposure
In the past decades, corrosion-induced damage has repeatedly led to severe component failure in prestressed concrete structures. This is typically caused by inadequate design or poor workmanship, leading to hydrogen-induced stress corrosion cracking and subsequent failure of the prestressing steel. To prevent such damage, metallic and epoxy resin coatings were sometimes applied to the steel to provide additional protection. However, these systems did not provide the required reliability. Thus, the use of high-strength stainless steel wire could be a possible alternative. Because of its...
