| What is the difference between hot dip galvanizing and zinc plating? |
|
The difference consists substantially in what follows:
- the method of hot dip galvanizing is carried out dipping the object into fused zinc at approximately 450° degrees. In that way processes of diffusion are started and the zinc penetrates in the steel creating an alloy with a strong adhering capacity. The ulterior zinc creates a pure layer of cathodic protection of remarkable thickness and strong adhesione and resistance.
- in the galvanic (electrolytic) process the parts are dipped into zinc watery salt solutions; applying an opportune electrical power in the solution the zinc comes attracted by the metal, consequentely it creates a superficial layer.
This method does not create any alloy between the steel and the zinc
The protecting layer adheres to the part gripping at the rughness of the steel and it's thickness is limited.
The thickness of the standard zinc plating is 8 mycron and the one of hot dip galvanizing is 78/86 mycron.
Upon request we can perform layers with various thickness.
