Key Features:

• Varieties of Galvanization: The two methods mostly used are hot-dip galvanization, where a metal part is dipped in a molten zinc bath; and, electro-galvanization, wherein thin layers of zinc are deposited upon the metal by means of electric current. Each technique has advantages and disadvantages with respect to protection and finish.
• Corrosion Resistance: Cold surfaces become an electrical insulator as zinc oxide skeleton forms and prevents corrosion from flowing directly to the underlying metal, wherein, if it is scratched, zinc takes over as it acts like a sacrificial anode thereby protecting the embedded steel beneath by corroding first.
• General Applications: In construction (roofs, fences, beams), in automotive production (body panels and chassis), or household items (pipes, hardware, or appliances), galvanized steel has gained popularity mostly due to its high strength and cost efficiency.

This capability completely defines the role of galvanization as it can sustain long-lasting protection against corrosion in various environments. Such steel will accommodate bridges, buildings, and other outdoor structures because this type of structures has been exposed to strong gale winds and blizzards. Galvanizing attributes in the automobile industry improve vehicle life by preventing rust. Now, continuous innovations are in the process, such as environment-friendly galvanization processes and alloy coatings that would provide better corrosion resistance to galvanization. Thus galvanization could be termed as a significant technique of the present manufacturing and infrastructure development.
