Galvalume coil/zincalum coil has many excellent characteristics:
1. strong corrosion resistance, 3 times that of pure galvanized sheet;
2. beautiful spangles on the surface, which can be used as building exterior panels.
3. Corrosion resistance
The corrosion resistance of "galvanized steel coil" is mainly because of aluminum, the protective function of aluminum. When the zinc is worn away, the aluminum forms a dense layer of aluminum oxide, preventing corrosion-resistant substances from further corroding the interior.
4. Heat resistance
Aluminum-zinc alloy steel plate has good heat resistance and can withstand high temperature of more than 300 degrees Celsius, which is very similar to high-temperature oxidation resistance of aluminized steel plate.
5. Heat reflective
The thermal reflectivity of galvanized steel sheet is very high, twice that of galvanized steel sheet, and people often use it as a thermal insulation material.
6. Economy
Because the density of 55%AL-Zn is lower than that of Zn, under the same weight and the same thickness of the gold-plated layer, the area of the galvanized steel sheet is more than 3% larger than that of the galvanized steel sheet.

Precautions for use
Storage of galvalume coils
: It should be stored indoors such as warehouses, kept dry and ventilated, and should not be stored for a long time in an acidic climate. When storing outdoors, it is necessary to prevent rain and avoid condensation caused by oxidation stains.
Transportation of galvanized coils: avoid external impact, SKID should be used to support steel coils on transportation tools, reduce stacking, and take rain-proof measures.
Galvanized coil processing: COILCENTER needs to use the same lubricating oil as aluminum plate when cutting. When drilling or cutting galvanized steel sheets, it is necessary to remove scattered iron filings in time.
