The following is from the American Galvanizers Association (AGA), “Inspection of Hot Dip Galvanizing Steel Products.”  Galvanized items should be visually inspected for the following: Bare spotsBare spots, defined as uncoated areas on the steel surface, are the most common surface defect and occur because of inadequate surface preparation, welding slag, sand embedded in castings, excess aluminum in the galvanizing …

INSPECTION OF WORK BEFORE DISPATCH TO THE GALVANIZER Fabricated assemblies, castings and other components for galvanizing should be inspected before despatch to the galvanizer to ensure that the articles are suitable for galvanizing. This will avoid costly rectification and delays at the galvanizing plant. Size and shape. Check that work is suitably sized and dimensioned for the handling and galvanizing facilities …
