Chain Link Fences: What Is The Galvanizing Process?

Galvanizing is a process where a zinc coating is applied to steel by immersing it in a bath of molten zinc.

There are several stages in galvanizing, which include:

PRETREATMENT

Chain Link Fences Cleaning:

Firstly, the fence passes through a cleaning process to remove possible traces of grease and oils by immersing them in an acid degreasing agent at about 35 °C.

Chain Link Fences Pickling

The pickling process removes rust and calamine, which are the most common surface contaminants of ferrous products, thus obtaining a chemically pure surface of the material. Also, It is diluted with hydrochloric acid at room temperature. So, the pickling time depends on the degree of surface oxidation of the parts and the concentration of the acid solution.

Chain Link Fences: Fluxing

The treatment with salts (mixtures of zinc chloride and ammonium chloride), removes any remaining traces of impurities and an intense cleaning of the metal surface. These salts act like fluxes in welding, i.e. they promote the wetting of steel surfaces by molten zinc, improving the reaction considerably.

Chain Link Fences: Galvanizing

This is an anticorrosive process by definition.

So, during the immersion of the products in the molten zinc, the zinc diffuses on the surface of the steel, resulting in the formation of different layers of zinc-iron alloys of different compositions. Also, an outer layer of pure zinc, highly resistant to water or soil.

Chain Link Fences: Quality Control

Finally, in Quality Control, verify the galvanized materials through visual inspection and tests, checking their suitability.
