The purpose of galvanizing is to form a zinc protective coating on steel or iron parts. But why is this useful? What are the main advantages of galvanizing?
Preventing corrosive substances: The zinc coating on galvanized metal prevents corrosive substances from reaching the weaker base metal. This can extend the service life of the substrate, especially in demanding applications.
Preventing rust: Galvanizing significantly delays rusting.
Creating a sacrificial anode: The zinc coating is consumed by corrosive substances, thus providing protection for the metal beneath until it is completely exhausted. Even if the scratch penetrates the coating, the zinc will run out before the iron.
Durable: The zinc coating formed by galvanizing is tough and long-lasting, usually providing decades of protection for the underlying metal.
Affordable: Galvanizing is a rather simple and affordable process that offers significant benefits at the lowest cost.
