The pre flux protects the work from further oxidation, thus resulting in prepared surface for galvanizing.
Galvanizing fluxes are formulated for accelerated speed, minimal fuming, less ash for uniform zinc coats. It is in solid and solution form which is used in the coating of tube, pipe, wire, small parts such as bolts and nuts, fencing in many parts. Flux is formation of high quality, adherent galvanized coating. It is a combination of organic and inorganic based surfactant, additives with wetting agents and salts of zinc ammonium chloride.
