Why are aluminum outdoor chairs less suitable for high-altitude environments?

Aluminum outdoor chairs are popular for their lightweight and rust-resistant properties, but they may not be the best choice for high-altitude environments. At higher elevations, extreme temperature fluctuations can cause aluminum to expand and contract, leading to structural weakening over time. Additionally, intense UV radiation at high altitudes can degrade the material's finish, making it prone to fading and corrosion. The lightweight nature of aluminum also makes it susceptible to strong winds, which are common in mountainous areas. For long-term durability in high-altitude settings, heavier, more weather-resistant materials like wrought iron or treated wood are often recommended.
