Hot-dip aluminium-zinc coated steel plate is a pre-coated steel plate obtained by hot-dip plating a layer of Al-Zn coating on both sides of a cold rolled steel plate of various strengths and thicknesses as a substrate, with a mass percentage of 55% Al (aluminium), 43.5% Zn (zinc) and 1.5% Si (silicon) in the composition of the plated layer, which combines the physical protection of Al and high durability as well as the electrochemical protection of Zn, and has the strength and plasticity of the base steel, and the corrosion resistance of the coating. The material has the strength and plasticity of substrate steel and the corrosion resistance of plating, which protects the metal substrate from internal corrosion. In addition, the surface has a highly decorative bright silver grey colour and regular patterns with a sense of embossment.

The corrosion resistance of "Aluminium-zinc plated steel coil" comes from the barrier layer protection function of aluminium and the sacrificial protection function of zinc. When zinc is sacrificed on cut edges, scratches and abrasions of the plating, aluminium forms an insoluble oxide layer which acts as a barrier. Aluminium-zinc-plated alloy steel coil has been in a variety of different atmospheric environments, outdoor exposure tests for more than 20 years, confirmed that aluminium-zinc-plated steel cutting edge protection, than galvanised steel is much better.

Aluminium-zinc-steel plated light steel has quite a few excellent characteristics: Strong corrosion resistance, 3 times that of pure galvanising; beautiful zinc flowers on the surface, can be used as building roof exterior panels. Abbreviation AZ150, aluminium-zinc-steel plates keel for a long time without colour change on the bare surface, such as chemical corrosion, the surface of the physical reaction occurs, the formation of aluminium protective film on the surface of the keel, so that the outside world of chemical substances and the keel separated from the separation of the keel, to protect the keel of the main body of the material, to prevent rusting.

Corrosion resistance is mainly because of aluminium, the protective function of aluminium. When the zinc is abraded, aluminium forms a dense layer of aluminium oxide, preventing the corrosion-resistant substances from further corroding the interior.

Aluminium-zinc-steel-plated alloy steel coils have been subjected to more than 20 years of outdoor exposure tests in a variety of atmospheric environments, confirming that aluminium-zinc-plated steel sheets provide much better protection for cut edges than galvanised steel sheets.

Aluminium zinc steel plating: AZ150 for short, aluminium zinc plating is galvanized corrosion 2-6 times, aluminium zinc plating keel long-term naked surface has no colour change, such as in the case of chemical corrosion, the surface of the physical reaction occurs on the surface of the keel to form a protective film of aluminium, so that the outside world of the chemical substances and the keel separated from the separation of the keel to protect the keel of the main body of the material, to prevent rusting.
