Apr 12, 2016

Roofing nails in the production process is the main electro-galvanized and hot-dip galvanizing process.

1. hot plating zinc is will zinc also liquefied of State Xia for, will corrugated nail put in liquefied of zinc solution layer in the, in high temperature in the, corrugated nail surface of iron and zinc mutual dissolved formed alloy layer. with this time, surface of zinc ion slowly of to railways diffusion, eventually all cover posted had, surface of zinc solution layer cooling Hou will into a layer zinc layer.

2. zinc electroplating are electrode positive and negative ions move to zinc plating, liquefied in a zinc anode and cathode cathode docking with roofing nails, anions move in the presence of electric current to the cathode. roofing nail itself steel body, zinc and steel plating forming micro-batteries, roofing nails of cathodic protection of steel to form the coating.
