What are the effects of prolonged UV exposure on stainless steel outdoor chairs?

Prolonged UV exposure can significantly impact stainless steel outdoor chairs, leading to both aesthetic and structural changes. Over time, ultraviolet rays may cause discoloration, fading the polished finish and giving the metal a dull appearance. While stainless steel is known for its corrosion resistance, continuous UV exposure combined with environmental factors like moisture can accelerate oxidation, potentially leading to rust spots. Additionally, UV radiation may weaken the protective chromium oxide layer, reducing the chair's overall durability. To mitigate these effects, regular cleaning, applying protective coatings, and using covers during peak sunlight hours are recommended. Choosing high-grade stainless steel (e.g., 304 or 316) with better UV resistance can also prolong the lifespan of outdoor furniture.
