How does WPC’s screw-holding power compare to aluminum in outdoor sofa joints?

When choosing materials for outdoor sofa joints, durability and screw-holding power are critical factors. WPC (Wood Plastic Composite) and aluminum are two popular options, but how do they compare in terms of screw retention?

WPC offers superior screw-holding power compared to aluminum due to its composite nature, combining wood fibers and plastic for enhanced grip. Aluminum, while lightweight and corrosion-resistant, tends to have weaker screw retention over time, especially in high-stress outdoor environments.

For outdoor furniture, WPC’s ability to maintain screw integrity ensures long-term stability, reducing the risk of loosening or joint failure. Aluminum may require additional reinforcement or specialized fasteners to achieve similar performance.

In summary, WPC outperforms aluminum in screw-holding power for outdoor sofa joints, making it a more reliable choice for durable, long-lasting furniture.
