What are the differences in thermal endurance limits between WPC and granite flower boxes?

When selecting outdoor flower boxes, thermal endurance is a critical factor, especially in extreme weather conditions. Wood-Plastic Composite (WPC) and granite are two popular materials, each with distinct thermal properties.

WPC flower boxes are engineered to withstand moderate temperature fluctuations. They resist warping and cracking under heat but may soften or expand in prolonged high temperatures. Their lightweight nature and UV-resistant coatings enhance durability.

Granite flower boxes, on the other hand, excel in thermal stability. Granite's natural density allows it to endure intense heat without damage, making it ideal for hot climates. However, its weight and cost can be limiting factors.

In summary, WPC offers versatility and affordability, while granite provides unmatched heat resistance. Your choice depends on climate, budget, and aesthetic preferences.
