Applications of Aluzinc & Prepainted Aluzinc coils

Aluzinc, Zincalume and Galvalume are different trade names of one product. Aluzinc is cold rolled galvanized steel with metal coating composed of Aluminium (55%), Zinc (43.4%) and Silicon (1.6%). It is formable, weldable and readily accepts paint finishes . DANA STEEL has a state of the art Galvanizing with DUAL POT system at it’s Continous Galvanizing Line facility in Dubai UAE. Herein Aluzinc Coils are manufactured in it’s Manufacturing Facility .

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. Then the aluminum part of the Aluzinc coating will persist for a longer period of time, and the protection will thereby remain
