Short answer: Galvanizing defects — bare spots from residual oxide or grease, dross inclusions from unfiltered zinc, rough or thick coatings from excessive withdrawal speed, and thin coatings from too-short immersion — usually trace back to surface preparation and bath control rather than the zinc itself. Preventing them means rigorous degreasing and pickling, filtered zinc, controlled withdrawal and correct dip time, with coating weight verified per the relevant standard and documented on the mill certificate.
