DX51D AZ Aluminum Galvanized Steel Sheet Coli 2500mm Width DX52D AZ
Product Description:
Aluzinc is used in applications where long life is an essential requirement. Aluzinc coated steel has superior long term corrosion resistance in most atmospheric conditions.
This is achieved through the combination of the sacrificial protection of the zinc and the barrier protection of the aluminum. Corrosion rates vary according to the severity of atmospheric conditions. Aluzinc steel coatings out-perform galvanized coatings from 2 – 6 times.
The protective mechanism for Alu-zinc and hot-dip-galvanized steel are such that the hot-dip-galvanized coating initially protects better but the zinc coat will gradually corrode away more and more in the vicinity of the edge and the protective effect will be lost.
