What is aluminium-zinc plated sheet
Aluminium-zinc plated sheet is a steel plate plating on the basis of zinc with the addition of aluminium (passivation protection), the general composition of 55% aluminium, 43.5% zinc, 1.5% silicon, with excellent resistance to atmospheric corrosion, corrosion resistance of galvanized sheet 2-5 times, but also has the high temperature corrosion resistance of aluminium plate, smooth surface, good appearance, but the formation of its plating and resistance to welding a little worse. In foreign countries generally about 40% of aluminium zinc plating used directly, about 60% of the plate is further as a colour coated substrate.
Uses: building roofs, walls, electrical cabinets, home appliances, automobiles, colour coated substrates, etc.
Base Metal Plate (Cold Rolled): It has the advantages of high strength, easy processing and economy, but it is prone to corrosion.
55% Alu-Zinc Steel Sheet: 55% Aluminium + 43.5% Zinc + 1.5% Silicon and other trace elements.
Alloy Layer: By forming a thin alloy layer between aluminium and iron, it inhibits the growth of brittle zinc-iron alloys and increases processability.
| SURFACE TREATMENT | DESCRIPTION OF USE |
| CHROMATE PASSIVATION(C) | Surface treatment for high-strength steel plates after hot-dip plating to reduce white rust during transport and storage |
| Chrome-free passivation(C5) | Surface treatments that require limiting the amount of hexavalent chromium, etc. in passivation solutions that are harmful to the environment and humans |
| Anti-finger print(N) | Surface treatment after the passivation process, which acts as a lubricant during processing, prevents fingerprints from staining during operation, and prevents premature blackening of the surface during use. |
| Chrome-free and fingerprint resistant(N5) | Surface treatment after the passivation process, in the process of lubrication, to prevent the operation of the fingerprint staining, to prevent the use of the surface of the process of premature blackening, and at the same time, the requirement to limit the fingerprint-resistant film harmful to the environment and human body, such as hexavalent chromium content |
| Oiled(O) | Surface treatment added after the passivation process to further reduce rusting during long-distance transport and long-term storage |
| Environment | Zinc Weight/ G/sqm |
