The purpose of electroplating zinc in cold galvanizing processing is to prevent corrosion of steel objects, thereby effectively improving the corrosion resistance and service life of steel. Steel will be weathered and rusted over time, and corroded by water or soil.

Every year in China, about one tenth of the total amount of steel is corroded, so in order to protect the service life of steel or its parts, cold galvanizing is generally used to process steel.

Feature 1:

Good corrosion resistance, fine and uniform combination, not easily penetrated by corrosive gases or liquids inside.

Feature 2:

Due to the purity of the new layer, it is not easily corroded in acidic or alkaline environments. Long term effective protection of the steel body.

Feature three:

After passivation with chromic acid, it forms various colors for use, which can be selected according to customer preferences. Galvanization is aesthetically pleasing and decorative.

Feature 4:

Zinc coating has good ductility and will not easily fall off during various bending, handling, impact, etc.

So, why do cold galvanizing processes possess these characteristic features? What is the principle behind it?

Cold galvanizing processing principle:

Due to the fact that zinc is not easily changeable in dry air and can produce a basic zinc carbonate film in humid environments, this film can protect internal parts from corrosion damage. Even if the zinc layer is damaged by certain factors, the combination of zinc and steel will form a micro battery after a period of time, making the steel substrate a cathode and protected.
