Zinc-Aluminium Coating

Hot Dipped Galvanized Steel Coils and Sheets

The composition of the coating is 95% zinc and 5% aluminium. The coating is also applied by means of a continuous hot dip galvanizing process on the both sides. The advantages is a very good ductilibility, an excellent forming performance and an excellent edge corrosion resistance.
