Anticorrosive coating of steel thicker the better?

Corrosion protection of steel structures are generally achieved by painting anti-corrosion paint, so many people think that the thicker anti-corrosion paint is certainly the better, and in fact, how thick steel anti-corrosion paint, not by our competent Willing to decide, mainly depends on the following three elements:

Corrosion-resistant steel spray
1, Corrosion of the workpiece in the environment, including the sun, salt spray, humidity, high temperature, acid, grease and so on.
2, the required life of steel components.
3, steel varieties of anti-corrosion paint. Different anticorrosive lacquers have different optimal film thickness, and the requirements for the thickness of lacquers in different environments are also different.
