The Life of a Zinc Coating is Directly Proportional to its Thickness. Although zinc coatings can be applied by several different processes, only hot dip galvanizing provides a continuous, tough, Like batch hot-dip galvanizing, the surrounding zinc will provide cathodic protection to these uncoated areas, but as there is much less zinc present, the best practice is to touch-up any

Continuous hot dip galvanizing operation entails joining, cleaning, annealing and cooling of cold-rolled steel strip to 455-460 oC before hot dipping in molten zinc (Zn) bath at 455-460 oC The European General Galvanizers Association has published an Environmental Product Declaration (EPD) for ‘Batch Hot Dip Galvanizing of Steel Products to EN ISO 1461 – For corrosion protection reasons, steel is often hot-dip galvanized. A distinction can be made between continuous strip galvanizing and batch galvanizing.
