Introduction: 

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.

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-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.
• Thermal reflectivity: Aluminium-zinc plated mild steel has a high thermal reflectivity, twice that of galvanised mild steel, and is often used as a thermal insulator.

Coating content classification

• 55% alu-zinc steel plate: the coating consists of 55% aluminium, 43.4% zinc and 1.6% silicon, the corrosion resistance is 2-6 times of galvanised sheet, characterised by high-temperature corrosion resistance, smooth surface, good appearance, but the plating of the molding and weldability is slightly worse.

Characteristics:

• Corrosion resistance: zinc is chemically active, in the air at room temperature, the surface generates a thin and dense layer of alkaline zinc carbonate film, which can prevent further oxidation, and aluminium in the air, can form a layer of insoluble oxides, in which the barrier protection function.
• Heat Resistant: Aluminium zinc plated sheets can be used in high temperature environments up to 315 degrees.
• Reflectivity: Aluminium-zinc coated sheets are highly reflective, with a heat reflectivity almost twice that of galvanised steel, making them ideal for use on steel metal roofs to achieve energy savings.
• Easy to paint: Aluminium-zinc-plated sheets from aluminium-zinc-plated sheet manufacturers have excellent adhesion between the sheet and the paint and can be painted without pre-treatment or weathering.
• The coating adhesion of the aluminium-zinc plating layer is relatively good, so it can be applied directly to advertising boards and general-purpose boards without pre-treatment such as weathering.

Advantages of Galvalume Steel which Compared with Galvanized 

Which is more scratch-resistant and durable, light steel keel galvanised or aluminium zinc plated?

The difference between galvanised and aluminium zinc plating

Lightweight steel coatings are divided into two types: galvanised and aluminium zinc plated:

Galvanised: the amount of galvanised light steel plating and can be determined according to its different use of the environment and function of the amount of galvanisation required; in order to strengthen the corrosion resistance, can be controlled in accordance with the different requirements of the thickness of the galvanised layer can be in the 120g/m2 - 275g/m2.

Galvanised steel sheet Z275 - i.e. galvanised steel sheet, Z275: zinc layer weight designation, indicating the weight of zinc contained in the steel sheet on both sides 275g/m2.

Galvanised Physical Changes: Galvanised is exposed all year round to react with oxygen in the air and the surface will blacken.

Aluminium zinc plating: aluminium zinc plated light steel has a number of excellent characteristics: strong corrosion resistance, 3 times that of pure galvanised; beautiful zinc flowers on the surface, which can be used as a building exterior panels. Abbreviation AZ150, aluminium-zinc-plated 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 zinc is abraded, aluminium forms a dense layer of aluminium oxide, preventing further corrosion of the corrosion-resistant material inside.

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

Heat reflectivity

Aluminium-zinc-plated mild steel has a high thermal reflectivity, twice that of galvanised mild steel, and is often used as a thermal insulator.
