ASTM A792m Roofing Material Metal Hot Dipped Anti-Fingerprint Galvalume Steel Dx51d Az275
Alu Zinc Coated Az150 Afp
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.
| 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 |
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.
