Galfan Wire manufacturers tell you that for steel wire, the advantages of the double-dipping process: First, galvanizing first and then galvanizing galvanized alloy has a large process latitude, and the problem of surface leakage plating can be avoided; second, the obtained coating is thicker and hot-dip plating The coating weight of A, B, C grades of zinc wire and A, B, C, D, E grades of steel strands can be achieved.
Galfan Wire manufacturers tell you that because of the double plating process, the thickness of GALFAN alloy coating can be the same as that of pure zinc coating, so in actual use, the corrosion resistance life can be increased by more than 1 time. The disadvantage of the double plating process is that it is difficult to control the composition of the alloy in the plating pot, the process flow is long, and the corresponding material consumption and energy consumption are also higher.
Galfan Wire manufacturers tell you that the reason why the corrosion resistance of the GALFAN alloy coating is higher than that of the pure zinc coating is due to the very active chemical properties of aluminum, when the GALFAN alloy coated steel wire is drawn out of the plating solution, a layer of gray will be formed on the surface. Thermal aluminum protective film. In the subsequent corrosion process, the zinc-rich phase is corroded first as the anode, so the aluminum content of the surface layer increases with the prolongation of corrosion time, the resulting protective film also increases, and the corrosion rate of the coating is also delayed.
The above information is the Galfan Wire Manufacturer's introduction and analysis of the benefits of the  galfan for using the double dipping process, hope it helps you.
