Galvanized
It is done in 2 ways, the first one is Electro Galvanized coating and the second one is Hot Dip Galvanized coating. With the hot-dip galvanizing method, the coating is done by dipping the material into the molten zinc (460C°). In this way, oxidation is prevented and the life of metals is extended, and air contact is prevented from rusting. Oxygen interacts with the metal, causing abrasions (rust), and the pieces are separated from the metal in layers, the strength of the metal decreases, and the image becomes dirty. Rusting is not only a visual defect, but also a chemical reaction that corrodes metal. With galvanization, a population is created on the metal in the coating, this population penetrates into every corner, inside, surface and cavities of the metal. It is applied to galvanized, iron or steel. Wear resistance is increased by coating the metal with zinc. The best way to prevent rust is coating application. The coating thickness decreases and loses every year, that is, zinc disappears in certain amounts every year, which allows the life to be determined beforehand. Since zinc is more reactive than iron or steel, first the zinc galvanized coating corrodes, protecting the iron or steel in the substrate.
