How do WPC outdoor sculptures compare to metal sculptures in terms of thermal expansion?
When selecting materials for outdoor sculptures, thermal expansion is a critical factor to consider. WPC (Wood-Plastic Composite) and metal are two popular choices, each with distinct properties. WPC outdoor sculptures exhibit lower thermal expansion compared to metal sculptures, making them more stable in fluctuating temperatures. Metal sculptures, especially those made from aluminum or steel, can expand and contract significantly with temperature changes, potentially leading to structural stress over time. WPC's composite nature provides better resistance to warping or cracking, ensuring longevity in outdoor environments. For artists and designers, understanding these differences helps in choosing the right material for durable and visually appealing outdoor art.
