What are the differences in thermal expansion mismatch between WPC and aluminum flower boxes?

When choosing flower boxes for outdoor use, understanding the thermal expansion mismatch between materials is crucial. Wood-Plastic Composite (WPC) and aluminum are popular choices, but they behave differently under temperature changes.

WPC flower boxes exhibit higher thermal expansion compared to aluminum. This means WPC expands and contracts more with temperature fluctuations, which can lead to warping or cracking over time. Aluminum, on the other hand, has a lower coefficient of thermal expansion, making it more stable in varying climates.

The mismatch in thermal expansion can affect the durability and appearance of flower boxes. WPC may require more maintenance to prevent damage, while aluminum offers long-term stability with minimal upkeep. Consider your local climate and aesthetic preferences when selecting between these materials for your outdoor planters.
