Why do cast iron outdoor chairs often feature thicker frames than aluminum versions?

Cast iron outdoor chairs often feature thicker frames compared to aluminum versions due to the inherent properties of the materials. Cast iron is heavier and more brittle, requiring thicker frames to ensure structural integrity and prevent cracking under stress. The added thickness also enhances durability, allowing the chairs to withstand harsh weather conditions and heavy use over time.

In contrast, aluminum is lightweight and more malleable, enabling manufacturers to create slender yet sturdy frames without compromising strength. The thinner frames of aluminum chairs make them easier to move and more suitable for modern, minimalist designs.

Ultimately, the choice between cast iron and aluminum outdoor chairs depends on preferences for weight, style, and longevity, with cast iron offering rugged durability and aluminum providing sleek practicality.
