How does the density of granite affect its load-bearing capacity for benches?

Granite is a popular choice for outdoor benches due to its durability and aesthetic appeal. One of the key factors determining its suitability for load-bearing applications is its density. Higher-density granite typically offers greater strength and resistance to wear, making it ideal for benches that need to support significant weight.

The density of granite, measured in grams per cubic centimeter (g/cm³), directly influences its load-bearing capacity. Denser granite varieties, such as those with a density above 2.6 g/cm³, are less porous and more resistant to cracking under pressure. This makes them perfect for high-traffic areas or public spaces where benches must endure constant use.

In contrast, lower-density granite may be more prone to weathering and structural fatigue over time. When selecting granite for benches, consider both the density and the intended environment to ensure long-lasting performance. Proper installation and maintenance further enhance the load-bearing capabilities of granite benches, making them a reliable choice for outdoor furniture.

By understanding the relationship between granite density and load-bearing capacity, you can make informed decisions for durable and sturdy bench designs.
