The aluminium-zinc alloy coating is applied in a similar way to traditional galvanised steel, by way of a continuous hot-dipped galvanized process that gives a coating on both sides of the material of 55% aluminium, 43.4% zinc and 1.6% silicon.
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 aluminium. Corrosion rates vary according to the severity of conditions, Aluzinc steel coatings out-perform galvanized coatings from 2 – 6 times. The protective mechanism for Aluzinc and hot-dip-galvanized steel are such that the hot-dip-galvanized coating protects better, and lasts longer.
