What is an anti-corrosion coating?

Anticorrosion paint is one of the most effective and cheapest ways to protect the metal against the corrosive effects of corrosion. Coatings can be applied to all metal. They can be used to protect entrance gates, sheet metal or metal parts of vehicles. However, one layer is usually not enough, usually three coats are needed in order for the coating to fulfill its protective function. Modern anti-corrosion products are produced in ecological ways and have minimal negative environmental impact. In addition, it is a non-flammable and non-edible matter, so it's usually harmless.
