Raw material information:
Zinc plating of steel is known to be critical to corrosion resistance. To improve anti-corrosion properties, the vast majority of industries around the world continue to use the most famous method of passivation treatment with chemicals containing hexavalent chromium.
This type of treatment prevents the formation of storage spots and white rust during transportation and storage. It also provides a high level of wear resistance at a cost effective cost.
Definition of galvanizing:
The galvanizing process is an industrial process by which a protective layer of zinc is added to steel or iron in order to protect it from rusting when exposed to various environmental factors such as water and oxygen in the air. Galvanizing on many columns and street signs, and this is what makes them appear silver, mainly due to the presence of a layer of zinc on them.
The importance of galvanizing:
The process of galvanizing the metal protects it from corrosion and damage as it gives it anti-corrosion properties and prevents the access of water and environmental factors to the iron layer, and the use of galvanized steel comes at a low cost compared to other materials that are not subject to rust such as expensive types of steel, aluminum and other materials, This is what makes many factories rely on the use of galvanized iron.
It should be noted that the galvanizing process appeared a very long time ago and was known to many human civilizations; However, it did not appear in the currently accepted form until the century before the last; Where a complete galvanizing process for metals was carried out by a French scientist, who subsequently obtained a patent, called (Stanislas Sorrell).
