To protect aluminum from concrete, use isolation methods such as plastic or rubber pads, washers, or gaskets to create a barrier between the aluminum and the concrete. This prevents chemical reactions that can lead to corrosion or staining. Ngoài ra, ensure proper drainage to avoid water accumulation, which can exacerbate issues. Applying a protective coating or sealant to the aluminum can also provide an extra layer of defense against concrete’s alkaline environment.
