Galvanised coating refers to a protective layer of zinc applied to metal surfaces, typically steel or iron, to prevent rust and corrosion. This process usually involves hot-dipping the metal in molten zinc, creating a durable and corrosion-resistant barrier. The zinc layer acts as a sacrificial anode, meaning it will corrode before the underlying metal does, extending the lifespan of the material. Galvanised coatings are commonly used in construction, automotive, and outdoor applications due to their effectiveness in harsh environments.
