How does wrought iron’s resistance to UV radiation compare to aluminum?

When choosing materials for outdoor applications, UV resistance is a critical factor. Wrought iron and aluminum are both popular choices, but they perform differently under prolonged sun exposure.

Wrought iron is highly durable but lacks inherent UV resistance. Over time, UV radiation can accelerate oxidation, leading to rust if the iron isn’t properly coated or maintained. Regular painting or powder coating is essential to protect wrought iron from UV damage.

Aluminum, on the other hand, naturally resists UV radiation due to its oxide layer, which forms a protective barrier. This makes aluminum a low-maintenance option for outdoor use, as it won’t rust or degrade as quickly as untreated wrought iron. However, aluminum may lose its luster over time without protective finishes.

For long-term outdoor durability, aluminum generally outperforms wrought iron in UV resistance. However, with proper care, wrought iron can still be a viable option for aesthetic or structural projects. Consider maintenance requirements and environmental conditions when selecting between these metals.
