4 minsPublished Oct 01, 2002Ungalvanized Weld Areas. Coating misses on weld areas are the result of the presence of welding Dark Staining Adjacent to Welds. Preparation chemicals that penetrate unsealed overlaps or via Dull Gray or Mottled Coatings. Reactive steels will produce thicker galvanized coatings that are Dross Pimples/Inclusions. Dross develops during the process of galvanization in the form of zinc White Storage Staining. After galvanizing, items stacked or stored in wet, not well-ventilated Ash Staining. Zinc ash can develop during the galvanizing process as the work is immersed in the Striations and General Surface Irregularities. Ridges and lines thicker than the nearby galvanized Runs, Drainage Spikes, and Puddling. These defects cannot be avoided during the hot-dip Bare Patches. Uncoated areas on the surface of galvanized work are because of not preparing the Rust Staining.

The process involves the dipping of both fabricated and unfabricated pieces into hot molten zinc, usually about 840° F (449°C). Quality galvanizing starts before the item is dipped into the molten zinc and in some cases even before fabrication is begun.
