Anti-rust painting
The paint can prevent the metal from the rust and enhance the adhesion. After painting the antirust paint the
metal can be isolated from air. The paint passivate the metal and prevent the metal from the rust. There are
physical binding and chemical binding caused by passivation layer. So the adhesion is strong.
Electro Galvanized Steel is a zinc coated metal that is produced through an electroplating process. This
process uses an electric current to plate the metal with zinc. This enhances its corrosion resistance.
The electro galvanized nails generally used in the package of some more sophisticated electronic
products,appliance,etc.
Hot-dip galvanized is the process of coating iron, steel or aluminum with a thin zinc layer, by passing
the metal through a molten bath of zinc at a temperature of around 860 °C. When exposed to the
atmosphere, the pure zinc reacts with oxygen to form zinc oxide , which further reacts with carbon
dioxide to form zinc carbonate, a usually dull grey, fairly strong material that stops further corrosion
in many circumstances.Hot dip galvanized nails widely used in bad environment is relatively poor,
such as corrosion of air and liquid; relatively humid, such as beach houses and parapets connection.
