No, you don't need to worry about that with Patio Serving Tray. Aluminum itself does not rust. It will not get the red/brown rust color that untreated steel can get; instead, it is oxidized to a cloudy and white powdery surface over a long period of time under adverse conditions. To protect against this oxidation, we use high quality aluminum and powder coating. The coating of the aluminum further acts as a protective layer against corrosion and creates a beautiful finish on the aluminum.
