GALVANIZING PROCESS

Surface preparation is the most important step in the application of coating. Failures in surface preparation will be apparent when the steel is withdrawn from the molten zinc.

A hot alkali solution is often used to remove organic contaminants such as dirt, paint markings, grease and oil from the metal surface. Grit–blasting, sand–blasting, or other mechanical means can also be used.

Scale and rust normally are removed from the steel surface by pickling in a dilute solution 18% by volume hydrochloric acid.

Fluxing removes oxides and prevents further oxidation on the metal surface , prior to galvanizing.

Fabricated items are immersed in the bath until they reach bath temperature. The zinc metal reacts with the iron on the steel surface to form a zinc/iron inter-metallic alloy.
