DuraZinc or Stainless Steel? Selecting the Right Corrosion Protection Solution for Anchor Bolts

Corrosion of anchor bolts can lead to several challenges during the service life of a connection and structure. Corrosion reduces the effective cross-sectional area of the threaded section and may consequently decrease the load-bearing capacity of the bolt. This can adversely affect both the serviceability and structural safety of the connection. Durability is particularly important in aggressive environments, where long-term performance and maintenance requirements must be carefully considered during the design phase.

To protect anchor bolts against environmental exposure, two principal approaches are available:carbon steel protected by a corrosion-resistance co...
