Galvaanilistes

Galvaanilistes, also known as galvanized iron or galvanized steel, refers to iron or steel that has been coated with a protective layer of zinc to prevent rusting and corrosion. The process of applying this zinc coating is called galvanization, which significantly extends the lifespan of metal products exposed to harsh environmental conditions.

The galvanization process typically involves immersing the metal in a bath of molten zinc, a method known as hot-dip galvanizing. Alternatively, zinc can be applied through electroplating, spraying, or other coating techniques. The zinc layer acts as a sacrificial barrier: when the coating is scratched or damaged, the zinc corrodes first, protecting the underlying iron or steel from oxidation.

Galvaanilistes is widely used in construction, automotive manufacturing, and outdoor applications due to its durability and cost-effectiveness. Common products include roofing materials, fencing, structural beams, and automotive parts. The zinc coating also provides some resistance to chemicals and salt, making it suitable for coastal and industrial environments.

While galvanized steel is highly durable, prolonged exposure to certain chemicals or high temperatures can degrade the zinc layer. Over time, the coating may also develop a white, powdery substance called zinc corrosion product, which does not compromise structural integrity but can affect aesthetics. Proper maintenance, such as cleaning and repainting, can further enhance its longevity.
