What is Galvanized Zinc Paint?
Galvanized zinc paint is a type of coating that provides a layer of protection to metal surfaces. It’s made up of zinc particles suspended in a binder, which, when applied, forms a protective barrier that prevents rust and corrosion. The zinc in the paint acts as a sacrificial metal, meaning it will corrode in place of the underlying metal, thereby protecting it from the elements.
Benefits of Galvanized Zinc Paint
