What are the differences in weight distribution between WPC and cast iron outdoor tree boxes?

When choosing outdoor tree boxes, understanding the weight distribution differences between WPC (Wood Plastic Composite) and cast iron materials is crucial for both functionality and installation.

WPC tree boxes are significantly lighter than cast iron ones, making them easier to transport and install. Their weight is evenly distributed due to the composite material's uniform density, reducing the risk of tipping or instability. This lightweight nature also minimizes stress on underlying surfaces like pavements or decks.

In contrast, cast iron tree boxes are much heavier, providing inherent stability and resistance to wind or accidental displacement. However, their uneven weight distribution—often concentrated at the base—requires sturdy foundations and careful handling during installation. The added weight can also strain surfaces over time.

For urban landscaping, WPC offers practicality with manageable weight, while cast iron suits high-traffic areas needing durability. Consider your project's needs to choose the best material for your outdoor tree boxes.
