When designing sheet metal parts, galvanised steel sheets are often used materials. As the name suggests, galvanised steel sheet is a material made by "galvanizing" "steel sheet". Let’s first introduce the manufacturing methods and basic knowledge.
Plating is a surface treatment that forms a metal film on the surface of metals or resins. Among them, forming a zinc coating is called galvanizing. Zinc combines with oxygen in the air to form a passivated oxide film. Therefore, its characteristic is that it has an extremely high rust prevention effect.
Additionally, zinc has a higher tendency to ionize compared to iron, meaning it oxidizes faster than iron. So, if iron (steel) is galvanised, even if small scratches temporarily appear on the plating surface exposing the underlying iron, the surrounding zinc will preferentially corrode, thereby preventing the iron from corroding. This phenomenon is known as sacrificial protection. Hence, galvanised coatings are mainly applied to iron (steel).
Due to its excellent corrosion resistance, galvanised steel sheet is used in many places. Besides being used as materials for power transmission towers and guide rails, it is also used in automobile running parts. It also has many applications as a building material. Apart from being used as materials for galvanised steel roller shutter doors and window guards, it is used in the form of galvanised sheets for the exterior walls and roofs of buildings.
