Why is aluminum outdoor seating prone to oxidation if unfinished?
Aluminum outdoor seating is highly durable and lightweight, but unfinished aluminum is prone to oxidation due to exposure to moisture, oxygen, and environmental elements. When aluminum is left untreated, its surface reacts with oxygen to form aluminum oxide—a thin, dull layer that can eventually lead to corrosion if not properly maintained. Unlike rust on iron, aluminum oxide forms a protective barrier, but prolonged exposure to rain, humidity, and salt air can break it down, causing pitting and weakening the material. To prevent oxidation, applying a protective finish, such as powder coating or anodizing, is essential. Regular cleaning and maintenance also help extend the lifespan of aluminum outdoor furniture.
