What are the thermal expansion properties of stone vs. concrete outdoor bar stools?

When choosing outdoor bar stools, understanding the thermal expansion properties of materials like stone and concrete is crucial for long-term durability. Stone, such as granite or marble, has a lower thermal expansion coefficient compared to concrete, meaning it expands and contracts less with temperature changes. This makes stone stools more stable in fluctuating climates, reducing the risk of cracking or warping over time. Concrete, while durable, tends to expand more under heat, which can lead to structural issues if not properly reinforced. For outdoor settings with extreme temperature variations, stone stools may offer better longevity, whereas concrete stools require careful design to mitigate thermal stress. Consider your climate and maintenance preferences when selecting the ideal material for your outdoor bar stools.
