The following is a summary of some of the inspections that should be performed …

Topic 1 – Inspection of the galvanizing process Topic 2 – Problems with galvanizing reactive steel Topic 3 – Measurement of galvanizing thickness Topic 4 – Preparation of galvanizing for painting Topic 5 – Coatings for galvanizing Topic 6 – Inspection of surface preparation and coating application

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 …
