Why is cast iron outdoor seating heavier than other metal options?

Cast iron outdoor seating is notably heavier than other metal options due to its dense material composition. Unlike aluminum or wrought iron, cast iron has a higher carbon content, which increases its weight while enhancing durability. This heaviness provides stability, preventing furniture from tipping over in windy conditions. Additionally, the weight contributes to its longevity, as cast iron resists wear and tear better than lighter metals. Its robust nature also makes it ideal for outdoor use, as it withstands harsh weather conditions without compromising structural integrity. Ultimately, the extra weight is a trade-off for unmatched strength and longevity in outdoor settings.
