What are the limitations of using WPC for cantilevered or suspended outdoor seating designs?

Wood-Plastic Composite (WPC) is a popular material for outdoor furniture due to its durability and low maintenance. However, when used for cantilevered or suspended seating designs, WPC has several limitations.

1. Load Capacity: WPC may not support heavy loads as effectively as traditional materials like steel or solid wood, making it less ideal for cantilevered structures requiring high strength.

2. Flexibility and Sagging: Over time, WPC can sag or deform under continuous stress, especially in suspended designs where even weight distribution is critical.

3. Weather Resistance: While WPC resists moisture, prolonged exposure to extreme temperatures or UV rays can weaken its structural integrity, leading to cracks or warping.

4. Design Constraints: WPC's limited flexibility restricts complex or dynamic shapes, often requiring additional support frames, which can increase costs.

5. Longevity: Compared to metal or hardwood, WPC may degrade faster in high-traffic outdoor settings, necessitating more frequent replacements.

For these reasons, designers must carefully evaluate WPC's suitability for cantilevered or suspended outdoor seating, balancing aesthetics with practicality.
