Are stainless steel outdoor sculptures prone to discoloration under prolonged UV exposure?
Stainless steel is a popular material for outdoor sculptures due to its durability and resistance to corrosion. However, prolonged exposure to UV rays can affect its appearance over time. While stainless steel is less prone to discoloration compared to other metals, it may develop a slight patina or surface changes under extreme conditions. Factors like alloy composition, finish, and environmental pollutants play a role. Regular cleaning and protective coatings can help maintain its original luster. For long-term preservation, choosing high-grade stainless steel (e.g., 316 marine grade) and proper placement are key.
