Why are aluminum outdoor chairs more likely to develop stress fractures over time?
Aluminum outdoor chairs are popular for their lightweight and rust-resistant properties, but they often develop stress fractures over time. The primary reason is metal fatigue caused by repeated stress from weight, movement, and environmental factors like temperature fluctuations. Aluminum, while durable, weakens under constant bending or pressure, especially at welded joints or thin sections. Exposure to UV rays, moisture, and salt air can accelerate corrosion and microfractures. Poor maintenance, such as ignoring small cracks or overloading chairs, also contributes to long-term damage. To extend their lifespan, regularly inspect for early signs of wear, avoid excessive weight, and store chairs during harsh weather. Choosing thicker-gauge aluminum frames can further reduce fracture risks.
