Flux inclusions can be created by the failure of the flux to release during the hot-dip galvanizing process. If this occurs, the galvanized coating will not form under the flux spot.  If the area is small enough, it can be cleaned and repaired. If the flux inclusion covers a large area, then the part must be rejected.  Flux deposits on the interior of a hollow part, such as a pipe or tube, as seen in the image to the right, cannot be repaired, and the part must be rejected.  Parts rejected for flux deposits may be stripped of their zinc coating and then regalvanized.
