What are the friction coefficients of PVC outdoor tree box surfaces when wet?

PVC outdoor tree boxes are widely used in urban landscaping due to their durability and low maintenance. However, understanding their friction coefficients when wet is crucial for ensuring safety, especially in public spaces.

Generally, the friction coefficient of PVC surfaces varies depending on texture and finish. Smooth PVC surfaces may have a lower friction coefficient (around 0.2–0.3) when wet, increasing slip risks. Textured or matte-finished PVC tree boxes can offer higher friction coefficients (0.4–0.6), improving traction in wet conditions.

For optimal safety, selecting PVC tree boxes with anti-slip coatings or ribbed designs is recommended. Regular maintenance, such as cleaning debris, also helps maintain slip resistance. Always verify manufacturer specifications for precise friction data under wet conditions.
