Hot-dipped galvanized technology protects the steel underneath from further corrosion. Hot-dip galvanized anchor protected self-drilling anchor bolt used in underground construction, because the self-drilling anchor bolts are usually made of steel, they are susceptible to corrosion. In this context, the self-drilling anchor bolt requires a structural design suitable for protection from corrosion.


The hot-dipped galvanized coating is excellent for use in moist atmospheres where more rust resistance is required than the standard zinc plated wedge anchors can provide.  Ensure the service life of the anchor rod.
