Aluminium Zinc Coating
Hot Dipped Galvanized Steel Coils and Sheets
The composition of the coating is 55% aluminium, 43.4 % zinc and 1.6 % silicon. The coating is also applied by means of a continuous hot dip galvanising process. Aluzinc-zinc coating offer an excellent corrosion resistance result from the barrier effect of the aluminium on the surface and the sacrifical protection of zinc.
Applications
- Construction: roofing, composite panels, tiles
- Domestic appliances: refrigerators, washing machines, microwave ovens
- Miscellaneous: boiler casings, computer casings, air ducts
