What are the main differences between granite, marble, and concrete for outdoor round tables?

When selecting materials for outdoor round tables, granite, marble, and concrete are popular choices, each with unique characteristics. Granite is highly durable, resistant to weathering, and requires minimal maintenance, making it ideal for long-term outdoor use. Marble, while elegant and visually striking, is more porous and susceptible to staining and weathering, requiring regular sealing. Concrete offers a modern, industrial look and is highly customizable but can crack over time if not properly maintained. Consider factors like climate, usage, and aesthetic preferences when choosing the best material for your outdoor round table.
