What are the key design parameters for stackable or interlocking WPC outdoor tree boxes?

Stackable or interlocking WPC (Wood-Plastic Composite) outdoor tree boxes are popular for their durability and modularity in garden and urban landscaping. Key design parameters include:

1. Material Quality: High-grade WPC ensures resistance to moisture, UV rays, and pests, extending the lifespan of the boxes.

2. Modularity: Interlocking mechanisms must be precise for easy assembly and stability when stacked.

3. Drainage System: Proper drainage holes prevent waterlogging, protecting plant roots.

4. Load-Bearing Capacity: The design must support the weight of soil, plants, and additional stacked units.

5. Aesthetic Appeal: Textured finishes and natural wood-like appearance enhance visual integration into outdoor spaces.

These parameters ensure functionality, longevity, and aesthetic harmony in outdoor settings.
