When selecting metal urban outdoor furniture, a common question arises: What are the legs made of, and will they rust? The answer depends on the specific material and protective finishes used.
Typically, the legs of such furniture are constructed from metals like steel or aluminum. Steel is strong and heavy, offering excellent stability. To prevent rust, quality steel furniture legs are often made with powder-coated finishes. This process involves applying a dry powder electrostatically and then curing it under heat, creating a durable, protective layer that shields the metal from moisture and corrosion. Some higher-end pieces may use stainless steel, which contains chromium for inherent rust resistance.
Aluminum is another popular choice, especially for its lightweight nature. Aluminum naturally forms a protective oxide layer, making it highly resistant to rust. It is often used in its alloy form for added strength and may also be powder-coated for enhanced color retention and extra protection against the elements.
So, will they rust? With proper materials and finishes, the risk is minimal. Powder-coated steel and aluminum legs are designed to withstand urban outdoor conditions. However, no material is entirely impervious. Damage to the coating, such as deep scratches, can expose the base metal to moisture, potentially leading to corrosion over time, especially with steel.
To ensure longevity, look for furniture labeled as "rust-resistant" or with "powder-coated" finishes. Regular maintenance, like cleaning with mild soap and water and checking for chips in the coating, will help preserve the furniture's appearance and structural integrity for years, keeping your urban outdoor space stylish and functional.
