Brief Introduction
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 |
| indoor environment | AZ70 or AZ100 |
| Suburban environment | AZ150 or AZ100 + painting |
| Urban or industrial areas | AZ150+ pre painted paint coating |
| Coastal Areas | AZ180+ thick paint coating |
| Usage | Steel Grade | Yield Strength(MPa) | Tensile Strength(MPa) | Elongation at break A80mm % ≥ |
| Generally used | DC51D+AZ | 190～360 | 270～500 | 22 |
| stamping | DC52D+AZ | 140～300 | 270～420 | 26 |
| deep drawing | DC53D+AZ | 140～260 | 270～380 | 30 |
| extra-deep washout | DC54D+AZ | 120～220 | 260～350 | 36 |
DECHO building colour steel plate can meet the need to use colour
steel plate as raw material for building. Decho Building Materials
colour steel plate is mainly processed into, for example, colour
steel corrugated board or colour steel composite sandwich board
after our colour steel plate is widely used in the construction of
airports, freezers, steel plants, warehouses, and other industrial
buildings and commercial buildings, such as the roof of the colour
steel tiles, colour steel plate sandwich walls and doors.
Reasons for choosing Decho Building Materials new material:
Provide extremely rich colour choices
The paint surface is long-lasting and bright
Surface coating will not fall off after stamping and has good
hardness with strong ductility and is not easy to scratch.
with excellent weather resistance, corrosion resistance, is to
ensure the durability of the premise of the building
