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.
Galvanized Aluminum Roll is an important alloy material which is often used in daily life. Aluminized zinc steel coil is aluminum zinc alloy structure, composed of 55% aluminum, 43% zinc and 2% silicon solidified at 600ºC and its entire structure is composed of aluminum - iron - silicon - zinc, forming a dense quaternary junction crystal of an alloy.
Main advantages
1, smooth surface, excellent resistance to atmospheric corrosion,
its corrosion resistance life is 2-6 times higher than hot-dip
galvanised steel;
2, with good heat and oxidation resistance, it does not change
colour for a long time under 300℃, and it can be used for a long
time around 500℃. In addition, the heat reflectivity of the product
is higher than 75%, which is 2 times higher than that of galvanised
sheet;
3, has excellent paintability and good processing performance. The
combination of machine material is strong, which is the best choice
for colour coated steel sheet substrate. Its processability and
weldability are similar to that of hot galvanised sheet, and it can
be processed by cold bending and stamping, and has a good
appearance.
Corrosion resistance: The corrosion resistance of "aluminized zinc
steel coil" is mainly due to aluminum, aluminum's protective
function. When the zinc wears down, the aluminum forms a dense
layer of aluminum oxide, preventing the resistance from further
corroding the interior.
Heat resistance: Aluminum zinc alloy steel coil has good heat
resistance, can withstand the high temperature of 300 degrees
Celsius, and aluminum plated steel plate high temperature oxidation
resistance is very similar, often used in chimney tubes, ovens,
illuminators and daylight lampshades.
Thermal reflectivity: Aluminized zinc steel coil has a high thermal
reflectivity, twice that of galvanized steel, and is often used as
insulation material.
Economy: Because the density of 55%AL-Zn is less than that of Zn,
the area of the aluminum-zinc coil is more than 3% larger than that
of the steel coil, given the same weight and the same thickness of
the gold coating.

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.
