WebSurface protection coating consisting of Zn and Aluminum sheets joined by an inorganic binder that acts as a sacrificial metal. The purpose of Zn coatings and their alloys is to protect the coated material from corrosion. This is achieved through two mechanisms: 1.-. Physical barrier isolating the coated material against the oxidizing medium. 2.-. WebThe zinc coating, when intact, prevents corrosive substances from reaching the underlying steel or iron. The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc. … pionnasse
