Frequently Asked Questions


It is a major industrial problem, as it can cause accidents (breakage of a part) and also represents a significant cost, since it is estimated that every few seconds 5 tons of steel are dissolved in the world, coming from a few nanometers or picometers, invisible in each piece but which, multiplied by the amount of steel in the world, constitute a significant amount.

Ferric oxide (Fe2O3), This is the form of rust commonly seen in rusted iron and steel structures that attacks everything from bridges to car bodies and is tremendously destructive.

4Fe(s) + 3O2(g) -> 2Fe2O3(s)

Red corrosion deteriorates the material as a result of electrochemical attack by its environment. Whenever corrosion is caused by an electrochemical reaction (oxidation), the rate at which it takes place will depend to some extent on the temperature, the salinity of the fluid in contact with the metal and the properties of the metals concerned.


The use of electrolytic zinc plating as opposed to zinc immersion galvanizing, paints, and other coatings, has several reasons:

The thickness of the protective layer of zinc is usually 10 microns and no more than 30 microns, so that the volume of the part is not increased. In some cases this is essential.

The protective layer is electrolytically adhered to the part. This layer becomes part of the part, so that the part can be bent, folded and modified without losing the protective layer.

Electrolytic zinc plating does not deform the materials, the process is carried out at room temperature.

The price of electrolytic zinc plating is more economical than other coating options.

Versatility in finishes, different passivates. Electrolytic zinc plating has a fine and shiny appearance, leaving no burrs or impurities.

The quality system guarantees professional finishes.

Possibly one of the best options to protect your materials against corrosion.


Accelerated corrosion tests in salt spray chambers are often used to evaluate the performance of metallic coatings, paints and treatments and pretreatments on coated metals.

Salt spray tests are widely used on galvanized steels, for example, where both coating protection and aesthetic deterioration of the coating can be evaluated.

The test hours have an approximate equivalence in real life. This equivalence depends on other factors such as contamination, environment where the material is going to be installed: rural areas, industrial areas, coastal areas, etc…
