What are the key differences between cast iron and steel landscape chairs in terms of durability?

When choosing outdoor furniture, durability is a top priority. Cast iron and steel are two popular materials for landscape chairs, but they differ significantly in longevity and maintenance.

1. Material Composition and Strength

Cast iron is heavier and more brittle, making it prone to cracking under impact. Steel, especially powder-coated or stainless variants, offers higher tensile strength and flexibility, resisting deformation better.

2. Weather Resistance

Cast iron requires regular sealing or painting to prevent rust, while steel—particularly galvanized or stainless steel—naturally resists corrosion. However, untreated steel can rust faster than cast iron in humid climates.

3. Maintenance Needs

Cast iron demands frequent upkeep to maintain its finish. Steel chairs, especially with protective coatings, are low-maintenance and often withstand harsh weather with minimal care.

4. Longevity

With proper care, cast iron can last decades but may chip or crack over time. High-quality steel chairs often outlast cast iron due to superior rust resistance and structural resilience.

For long-term durability in outdoor settings, steel landscape chairs generally outperform cast iron, especially when coated for extra protection. However, cast iron’s classic aesthetic may appeal to those willing to invest in maintenance.
