BENEFITS OF GALVANIZING

GALVANIZING PROCESS
MAJOR CLIENTS
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 Failures in surface preparation will be apparent when the steel is withdrawn from the molten zinc.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 used to removeorganic contaminants such as dirt, paint markings, grease and oil from the metal surface by grit-blasting, sand-blasting or other mechanical means.
SURFACE PREPARATION CAUSTIC CLEANING
Scale and rust are removed from the steel surface by pickling in a dilute solution of 18% by volume hydrochloric acid.
PICKLINGFluxing removes oxides and prevents further oxides from forming on the surface of the metal prior to the galvanizing
FLUXINGFabricated items are immersed in the galvanizing bath until they reach the bath temperature. The zinc metal reacts with the iron on the steel surface to form a zinc/iron intermetallic alloy.
