How do cast iron outdoor chairs handle repeated exposure to freeze-thaw cycles?

Cast iron outdoor chairs are renowned for their durability and classic appeal, but how do they fare under repeated freeze-thaw cycles? When exposed to fluctuating temperatures, moisture can seep into microscopic cracks in the iron, expanding as it freezes and potentially causing damage over time. However, high-quality cast iron chairs are often coated with protective finishes like powder coating or enamel to minimize water penetration and rust. Regular maintenance, such as cleaning and reapplying sealants, further enhances their resilience. While cast iron is inherently sturdy, proper care ensures these chairs remain functional and aesthetically pleasing despite harsh weather conditions. For longevity, storing them indoors during extreme winters or using protective covers can significantly reduce wear from freeze-thaw cycles.
