Function:
Galvanizing the metal can make it corrosion resistant.
Without protective zinc coating, metal will always be exposed to elements and will be oxidized and corroded faster.
In terms of corrosion prevention, galvanized steel is an economical and effective alternative to austenitic stainless steel, aluminum and other materials.
Operating principle:
First, it forms a protective coating that separates the metal from the surrounding environment. The zinc layer prevents water, moisture and other elements in the air from corroding the steel. If the zinc coating is scratched carelessly, and the scratch is very deep, the metal is exposed and easy to corrode.
Galvanizing can also protect metals by “galvanic corrosion”. When two metals with different electrochemical composition contact with the existing electrolyte, electrical corrosion will occur. According to the atomic structure of two metals, one is the anode and the other is the cathode. The rate of anodic corrosion is faster than its own corrosion, while the rate of cathodic corrosion is slower than its own corrosion. Zinc is used for galvanizing because it acts as an anode when in contact with many different types of metals. Since the zinc coating in contact with the base metal is usually an anode, the corrosivity of the base metal or cathode is slowed down.

Short comments: Galvanizing is one of the most widely used methods used to protect metals from corrosion. It applies a thin zinc coating on the thicker base metal, which can make the metal affected by the surrounding environment.
