What are the risks of thermal expansion in PVC outdoor seating joints?
Thermal expansion in PVC outdoor seating joints can lead to significant risks, including joint failure, cracking, and reduced structural integrity. PVC, a popular material for outdoor furniture, expands and contracts with temperature fluctuations, which may weaken joints over time. Prolonged exposure to sunlight and extreme weather accelerates this process, causing misalignment or even breakage. To mitigate these risks, manufacturers often design joints with expansion gaps or use flexible adhesives. Regular maintenance, such as inspecting for cracks and ensuring proper installation, can also extend the lifespan of PVC outdoor seating. Understanding these risks helps in choosing durable furniture and implementing preventive measures.
