What are the risks of metal fatigue in wrought iron outdoor chairs over decades?

Wrought iron outdoor chairs are prized for their durability and classic aesthetic, but over decades, they can suffer from metal fatigue—a gradual weakening of the material due to repeated stress and environmental exposure. The primary risks include:

1. Structural Weakening: Constant weight load and movement can cause microscopic cracks, leading to eventual failure.

2. Corrosion and Rust: Moisture and oxygen accelerate rust, thinning the metal and compromising strength.

3. Joint and Weld Deterioration: Stress points like welds or joints are prone to cracking over time.

4. Surface Degradation: Paint or protective coatings wear off, exposing the iron to further damage.

5. Sudden Breakage: Undetected fatigue can result in unexpected collapses, posing safety hazards.

To mitigate these risks, regular inspections, rust removal, and protective coatings are essential. Proper care can extend the lifespan of wrought iron chairs, ensuring they remain both functional and beautiful for years to come.
