What is the difference between Megali and Dacromet coating?

In the casting process of industrial automobiles, we need to use certain anti-corrosion technology. Because we know that the base parts of automobiles are made of steel materials through certain processes. If the steel is not treated with anti-corrosion treatment, it will rain or It is very easy to be corroded in severe weather such as snowfall, and poses a certain threat to the driving safety of the truck scale.
Under such a premise, human scientists have invented a variety of anti-corrosion methods for steel base parts, and Megali and Dacromet are one of the more common anti-corrosion methods. So what is the difference between these two anti-corrosion methods? Below we have Please let the technicians from the processing factory of Megali introduce to you:

Megali coating is used for automotive fastener products. The production process is first electroplating and then coating, and its anti-corrosion effect is good. Dacromet process is also a commonly used automotive anti-corrosion coating process. Its advantages are high flatness and smooth surface , good aesthetics. Various processing companies have various types of coatings, and different types of coatings have different functions.
Generally speaking, Megali coating is mainly used by North American customers and originated in America; Dacromet originated in Japan, and Japanese customers use it more; there is also a Delcon coating that is more commonly used by European customers.
Now my country's anti-corrosion technology has also been greatly improved with the improvement of my country's industrial level, and many automobile industries are also developing rapidly, making up for the shortcomings of the domestic automobile market.
