What is the purpose of galvanizing metals?

The primary purpose of galvanizing metals is to prevent rusting. This process involves coating the base metal, commonly steel or iron, with a layer of zinc. The zinc acts as a sacrificial anode, meaning that it will corrode before the underlying metal does. This protective barrier prevents moisture and oxygen from reaching the metal surface, significantly reducing the risk of corrosion and extending the lifespan of the metal.

The effectiveness of galvanizing in rust prevention is well established; it is widely used in various applications, from construction materials to outdoor equipment. The durability of the zinc coating contributes to the longevity and maintenance of the objects it protects, making galvanizing a crucial method in preserving metal integrity in various environmental conditions.
