What are the effects of prolonged shade on the corrosion rate of aluminum chairs?
Prolonged shade can significantly influence the corrosion rate of aluminum chairs, primarily due to moisture retention and reduced evaporation. While aluminum naturally forms a protective oxide layer, constant shade creates a damp environment that accelerates localized corrosion, especially in coastal or humid areas. Shade also limits UV exposure, which can slow the degradation of protective coatings. Factors like alloy composition, surface treatment, and air pollutants further determine corrosion susceptibility. Regular maintenance and proper ventilation are recommended to mitigate these effects and extend the lifespan of outdoor aluminum furniture.
