Galvanizavimas

Galvanizavimas is a metal coating process that involves applying a protective layer of zinc or zinc-iron alloy to the surface of steel or iron materials. The process involves dipping the metal object into a bath of molten zinc, where it undergoes a series of chemical reactions that form a strong bond between the metal and the zinc coating.

The galvanizing process was first developed in the 18th century, and it has since become a widely used method for protecting metal against corrosion. The zinc coating serves as a sacrificial anode, meaning that it will corrode in preference to the underlying metal, thereby protecting the metal from rust and decay. Galvanizavimas is commonly used for steel lattices, fencing, roofing, and other applications where the metal is exposed to the elements.

The galvanizing process consists of several stages, including shot blasting to clean the metal surface, followed by a bath of molten zinc. The metal is then removed from the bath and allowed to cool, resulting in a thick, even layer of zinc on the surface. The resulting galvanized layer is typically 20-100 micrometers thick and can last for many years, depending on environmental conditions. Galvanizavimas has several benefits, including improved durability, reduced maintenance costs, and increased lifespan for metal structures.

Galvanizavimas is widely used in various industries, including construction, automotive, and manufacturing. The process is also eco-friendly, as it reduces the need for paints and other coatings that may contain toxic chemicals.
