Steel Coating Alloys

Semco manufactures two types zinc coating alloys (Brightener); 5% Aluminum and 10% Aluminum with the balance percentage being SHG Zinc. Steel coating alloys are used for the protection of iron and steel from corrosion. The 5% Aluminum coating gives 2 times the long-term corrosion resistance versus pure zinc coating. Most steel coating alloys are hot dipped, in which the zinc and steel form a bond. This layer or bond can vary in thickness depending according to it's application.
