Hot-Dip Galvanizing Layer Formation Process
The formation process of the hot-dip galvanizing layer is the process of forming an iron-zinc alloy between the iron matrix and the outermost pure zinc layer. During hot-dip galvanizing, an iron-zinc alloy layer is formed on the surface of the workpiece, making the iron and the pure zinc layer tightly combined.
When the iron workpiece is immersed in molten zinc, a solid solution (body core) of zinc and α iron is first formed on the interface. This is a crystal formed by zinc atoms dissolving in the matrix metal iron in the solid state. The two metal atoms are fused, and the attraction between the atoms is relatively small.

We supply a wide range of steel product including galvanized steel, galvalume steel, PPGI, PPGL, corrugated steel roofing sheet, stone coated steel sheet, as well as aluminum and color coated aluminum.


Galvanized/Galvalume/PPGI/PPGL steel are widely used for roofing of house and villa, vegetable shed, wall cladding, prefabricated houses, warehouses, agricultural greenhouses, breeding houses and other construction.
