Are granite outdoor trash cans more resistant to fading from sunlight than concrete?

When selecting permanent outdoor trash receptacles, many property owners debate between granite and concrete options regarding their resistance to sun fading. Granite, being a natural igneous rock formed under extreme heat and pressure, possesses exceptional mineral density that provides superior protection against UV radiation. The crystalline structure of granite contains quartz, feldspar, and mica that naturally reflect sunlight, allowing it to maintain its original coloration for decades with minimal fading. Concrete, while durable, is a porous manufactured material composed of cement, sand, and aggregates that gradually deteriorates when exposed to direct sunlight. The chemical composition of concrete makes it susceptible to photodegradation, where UV radiation breaks down molecular bonds in surface materials, causing noticeable color fading within just a few years. Furthermore, granite's non-porous surface prevents moisture absorption that could accelerate fading, whereas concrete's permeability allows water penetration that intensifies sun damage. Professional landscape architects consistently recommend granite for permanent outdoor installations in sunny locations because its color-fast properties ensure long-term aesthetic appeal without requiring protective sealants or frequent maintenance. For maximum fade resistance in harsh sunlight conditions, granite outdoor trash cans demonstrably outperform concrete alternatives.
