| retain the bright metallic luster for a long period | |
| Oil | minimize the tendency for humid-storage stain |
| Chemical Treatment and Oil | The chemical treatment provides very good protection against humid-storage staining, while the oil provides lubricity for operations. |
| Dry | must be transported and stored with special precautions to preserve low-humidity conditions. |
| Anti-finger print | minimize the chance of humid-storage staining forms a dark gray surface discoloration on the surface |
12) Application of Full Hard Galvalume Steel Coil:
a. Construction: roofing, cladding, structural sections, composite panels, etc.
b. Electric appliance: washing machine, refrigerators, toaster, microwave, etc.
c. Others: air duct, lighting, computer casing, etc.
Manufacturing Flow of Full Hard Galvalume Steel Coil Azfull Hard50 :
Feature of Full Hard Galvalume Steel Coil Azfull Hard50 :
1) Full Hard Galvalume Steel is composed of 55% aluminum, 43.5% zinc and 1.5% Silicon.
2) Full Hard Galvalume steel is formable, weldable and paintable.
3) Full Hard Galvalume steel has superior corrosion resistance in the most atmospheric conditions. This is achieved through the combination of the sacrificial protection of the zinc and the barrier protection of the aluminum.
4) Full Hard Galvalume Steel coating out-perform galvanized coating from 2-6 times than hot dip galvanized steel.
