Thin metal sheets refined with zinc magnesium are not only thinner and more durable but they also offer a notably better corrosion resistance than common thin metal sheets with zinc coating and they also dispose of excellent protection against paint creep Besides zinc the alloy of the zinc magnesium coating also contains magnesium and aluminum of up to eight per cent The excellent corrosion resistance is based on the interaction of two main mechanisms the cathodic corrosion protection and the protective barrier effect The general cathodic corrosion protection of a zinc magnesium coating can be compared to the one of conventional zinc coating However the mixture of zinc magnesium aluminum alloy forms an additional tight compact and structured surface layer against white rust corrosion and this makes the difference The layer offers a notably improved barrier against progressive corrosion The result is as follows Depending on the potential corrosion the zinc magnesium coating is only half as thick as a conventional zinc coating Refined thin metal sheets The all rounders for sun shading 4
