In order to increase the corrosion resistance of the sheet steel, the surface is coated with zinc plating or electrolytic coating. The coating is generally made in 100-300 gr / square meters on both surfaces. Chromate solution or oil applied to the surface of the coated material is applied to protect it against white rust.
Zinc plating provides excellent corrosion resistance to galvanized material due to zinc-like protection against corrosive elements. The end-use life depends on the thickness of the coating and the corrosivity of the environment (damp, salt etc.). This process will create excellent surface appearance and therefore can be used without any surface treatment.
Additionally, galvanized steel can be drawn deeply and easily as they retain their forming properties.
Suitable surface can also be easily painted after pre-treatment. It allows to be presented as a finished sheet to the end user by being painted and shaped before use. Galvanized steel can also be welded by many known welding methods.
Corrosion resistant galvanized steel sheet is a type of material that provides the best requirements for the automotive industry. It is used by automotive manufacturers to produce both internal and external surface parts and thus guarantee a lifetime warranty against corrosion.
In the construction sector, hot dipped galvanized sheets are provided with suitable form; roofing, the inner and outer side of the buildings as a panel or sandwich panel among other wide ranges of applications.
Due to its long life; it is also used widely in the manufacture of white appliances, (on unseen surfaces it’s plain , on the visible surfaces it’s painted sheet) is the preferred product in the manufacture of ventilation devices.
To summarize, this steel product with its corrosion resistance, low initial and life-cycle costs, durability, longevity, availability, versatility, sustainability, and aesthetics is an important for many sectors of the industrial economies.
