Architectural aluminum sheets come with a variety of surface treatments that serve to improve their appearance, durability, and performance. These treatments make the aluminum suitable for a wide range of architectural applications.
One commonly used surface treatment is anodizing. This process entails immersing the aluminum sheet in an electrolytic solution and applying an electric current to create a protective oxide layer on its surface. This oxide layer can be dyed to achieve the desired color or left clear to maintain a natural metallic appearance. Anodized aluminum sheets are highly regarded for their excellent resistance to corrosion, scratches, and color fading.
Another surface treatment option is powder coating. In this method, a dry powder is electrostatically applied to the aluminum sheet and then cured in an oven. The powder melts and fuses to the surface, resulting in a smooth and durable finish. Powder coating offers exceptional color retention, weather resistance, and resistance to chipping and cracking.
A third type of surface treatment is PVDF coating, which involves applying a high-performance fluoropolymer resin called polyvinylidene fluoride to the aluminum sheet through a coil coating process. PVDF coatings are known for their exceptional resistance to fading, chalking, and chemical attack, making them perfect for exterior applications where color retention and durability are crucial.
Additionally, there are various mechanical surface treatments available for architectural aluminum sheets. These treatments, such as brushing or polishing, can be employed to achieve the desired texture or reflectivity on the surface. Mechanical treatments allow for the creation of brushed, satin, or mirror-like finishes, adding aesthetic appeal to the aluminum sheet.
To summarize, architectural aluminum sheets can be treated using anodizing, powder coating, PVDF coating, or mechanical treatments. Each treatment offers unique advantages and characteristics, enabling architects and designers to select the most suitable option for their specific project requirements.
