8.Coating Layers of hot dip aluminium coated steel:
1. Heat Resistance
When continuously exposed to temperatures up to 450°C, ALCOAT shows very little change and keeps its attractive surface brightness. This is a clear advantage over galvanized steel coil and cold-rolled steel coil under the same conditions.
2. Heat Reflectivity
At 450°C, the sleek surface of ALCOAT reflects approximately 80% of heat. In the presence of infrared rays, the reflection rate can reach as high as 95%. This makes ALCOAT an ideal material for heat reflector plates used in toasters, ovens, gas ranges, and oil stoves.
3. Corrosion Resistance
Aluminum naturally offers better corrosion resistance than metals like manganese, molybdenum, chromium, tungsten, cadmium, iron, and zinc. Thanks to the stable aluminum oxide film on its surface, ALCOAT performs significantly better than galvanized coil in most environmental conditions.
4. Green Environmental Performance
ALCOAT is harmless to human health and qualifies as an environmentally friendly product. Additionally, the aluminum-coated plate is fully recyclable.
5. Processing Performance
Aluminized steel sheets can be processed using the same methods and equipment as standard steel plates, offering excellent workability without special requirements.
6. Weldability
Due to aluminum's soft nature and strong electrical conductivity, ALCOAT welds easily with good heat dissipation at the welded joint. Moreover, because its coating has a higher melting point than galvanized coatings, it resists flowing during welding, resulting in a small melt zone. This means high welding currents are not needed, unlike with galvanized steel plates.
7. Surface Appearance
ALCOAT maintains a long-lasting, shiny finish while delivering superior corrosion resistance and weathering performance compared to many traditional coated steels.
Used in key parts of vehicle exhaust and fuel systems where high heat resistance and corrosion protection are essential.
Ideal for heating-related appliances that require excellent heat reflectivity, stable performance under high temperatures, and long-lasting surface appearance.
Suitable for industrial building applications demanding fire resistance, weather resistance, and durability against corrosive environments.
