The Process of Galvanization Explained
Galvanization is a vital process in metal protection, specifically designed to
combat corrosion in steel and iron products. The process typically involves coating steel
with a layer of zinc, which serves as a sacrificial anode. This means that when steel comes into
contact with moisture or other corrosive elements, the zinc corrodes instead of the underlying metal,
thereby extending the lifecycle of the product.
According to a report from the American Galvanizers Association, galvanized steel can last up to 70 years, significantly reducing
maintenance and replacement costs for industries reliant on metal components.
The galvanization process can be conducted through various methods, including hot-dip galvanizing
and electro-galvanizing.
Hot-dip galvanizing involves submerging steel into molten zinc, allowing for an extensive coating that can reach thicknesses of
85 microns or more. Conversely, electro-galvanizing employs an electrical charge to deposit
zinc onto the steel surface, resulting in a more uniform and thinner layer, often less than 20 microns.
Each method has its specific applications; for instance, hot-dip galvanization is favored in construction and infrastructure due to its
robust protective qualities, while electro-galvanization is frequently used in automotive manufacturing, where a smoother surface is
required for aesthetic and functional purposes.
Reports indicate that the global market for galvanized steel is on the rise, projected to reach
approximately $200 billion by 2025, underscoring its critical role across various sectors.
