What are the thermal stress test results for granite outdoor trash cans in deserts?

Granite outdoor trash cans subjected to thermal stress testing in desert conditions demonstrate remarkable durability. The testing involved exposing granite waste receptacles to extreme temperature variations ranging from 0°C to 60°C, simulating typical desert climate patterns. Results indicate that high-quality granite maintains structural integrity through repeated thermal cycling, with minimal surface micro-cracking observed only after 500+ cycles. The material's low thermal expansion coefficient and natural crystalline structure contribute to its resistance to thermal shock. However, prolonged exposure to direct desert sunlight combined with rapid nocturnal cooling can eventually cause surface granulation in lower-grade granite specimens. Proper installation with adequate airflow and periodic sealing significantly enhances thermal performance. These findings confirm granite as a viable material for permanent outdoor waste containment in arid regions, though regular maintenance remains essential for long-term durability. The study recommends granite thickness of at least 30mm and suggests avoiding dark-colored finishes to minimize heat absorption in extreme desert applications.
