Principle Of Galvanized Channel Steel

The hot-dip galvanized layer is formed by three steps of zinc in a high-temperature liquid state:
1. The surface of the iron base is dissolved by zinc liquid to form a zinc iron alloy phase layer;
2. The zinc ions in the alloy layer further diffuse towards the matrix to form a zinc iron mutual solution layer;
3. The surface of the alloy layer is enveloped by a zinc layer.
