Galvalume Steel Coil(55% Aluminium-Zinc Alloy Coated Steel Coil)
Aluminium-zinc steel is composed of an aluminium-zinc alloy structure, consisting of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600 degrees Celsius. Its entire structure consists of aluminium - iron - silicon - zinc, the formation of dense tetrameric crystals of an alloy coated steel.
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.
Attentions in Transportation and Storage:
1. Galvanized Steel Coils should be stored in neat and tidy environment to avoid possible corrosioncaused by all kinds of corrasive medium.
2. The ground for storage should be flat, without hard object, and with sufficient loading-bearing capacity.
3. Storage environment should be dry and ventilated. Avoiding storing outdoors or with dew or with wide temp difference.
4. Coil could not be dragged lest the burr caused by slicing will scratch the coil surface underneath. Coil should be handled with care, without hitting any hard object.
