What are the differences in thermal expansion between stainless steel and cast iron outdoor chairs?
When choosing outdoor furniture, understanding the thermal expansion properties of materials like stainless steel and cast iron is crucial for long-term durability. Stainless steel has a lower coefficient of thermal expansion compared to cast iron, meaning it expands and contracts less with temperature changes. This makes stainless steel chairs more stable in fluctuating climates, reducing the risk of warping or structural stress. Cast iron, while robust, expands more significantly under heat, which can lead to cracking or joint loosening over time. For outdoor use, stainless steel's resistance to thermal expansion often makes it a superior choice for maintaining structural integrity in varying weather conditions.
