Galvanizing is a process of imparting a sacrificial zinc coating on the iron or steel surface, thereby protecting the surface from atmosphere. Method of application differs according to the need and availability of measures.
The most popular galvanizing method is Hot Dip Galvanizing which is adaptable to almost all types of fabricated and non fabricated items. Flux type Continuous Galvanizing Line is such a kind where iron or steel strips are degreased, pickled and fluxed for surface preparation before dipping into the molten zinc.
Major Steps :
ALKALINE CLEANING - Removing oil, grease and soil from steel surface is crucial, otherwise dissolution of iron oxide / scale by pickling will be retarded.
ACID PICKLING - Ferrous metals have a surface coating of metallic oxide and / or scale which must be removed before zinc coating can be applied successfully. Pickling involves immersing the work in an acid to dissolve the scale or oxide film.
FLUXING - Liquid flux is recommended for continuous galvanizing line (C.G.L). It is used directly without any dilution. It has the ability to keep the sheets free from oxides by removing the rust blush prior to dip in the zinc bath. It also improves the zinc – iron adhesion in the galvanizing process.
PASSIVATION - Chromate conversion coating chemical is applied on galvanized iron and zinc –aluminum surfaces. It imparts excellent corrosion resistive coating that protects the underlying surface from weathering.
In case of nonox lines no fluxing is required. Further, depending on the sheet condition, acid pickling stage may also be omitted.

Alkaline cleaning removes organic soils such as rust preventative oils and lubricants. Multi-metal cleaners reduce or eliminate etch on all non-ferrous metals such as galvanized, galvalume and aluminum surfaces.
In addition, cleaners are specially designed to reduce foaming and provide maximum cleaning effectiveness.

Conversion coating enhances the corrosion resistance property on the pretreated galvanized, galvalume and aluminum surface. It also helps inhibit the under paint corrosion creeping process that in turn increases the object life.
Conversion coating reinforces the bond between the paint film and the surface.
PHOSCHEM 213 is a nitrate-nitrite accelerated zinc phosphating chemical used by immersion process at ambient temperature. It produces a smooth, compact, uniform coating on steel and zinc surfaces.

FLUXOL 336 is a liquid flux recommended for continuous galvanising line (C.G.L). It is used directly
without any dilution. The flux is highly stable at galvanising temperature. Chemically active flux effectively
removes impurities from the pickled steel to facilitate trouble free iron-zinc reaction.

PASSIVATING CHEMICALS :
Zinc is also a sensitive metal which forms white rust on exposure to air and moisture. The corrosion products give an unsightly, mottled surface consisting of the loose powder that makes it unfit for the industrial and domestic uses. White rust damages long-term protection of the base steel. Passivation of the galvanized surface is inevitable for long life of the articles.
1. Alibond 292 – It is a hexavalent chromium based chemical process, which produces a protective colourless chromate conversion coating on galvanized iron. The coating protects the surface from corrosion and finger staining and renders a gloss to the surface. It can be used by dip or spray.
2. Alibond 304 – Due to the hazardous nature of hexavalent chromium industries prefer trivalent chromium based products. It is a trivalent chromium based chemical process, which produces a protective almost colourless to very light bluish chromate passivating film on galvanized iron. It can be used by dip or spray in galvanizing plants and specially recommended for continuous strip lines.
3. Zipac 305 (Non chrome) – It is a unique eco friendly product free from chromium. It is a water soluble conversion cum passivating chemical, ideally suitable for zinc coated metal surfaces. The chemical forms a thin film over the zinc coated steel (G.I.), which forms a protective non-chrome layer to improve the corrosion resistance properties of the treated metal. ZIPAC 305 may also be used effectively for aluminium –zinc coated strips. The toxicity profile of chromium and pollution effect of chromates can be eliminated by using the new generation product in coil lines.
