Co-extrusion WPC wall cladding typically use recycled plastic and wood flour as raw materials, and the product itself is 100% recyclable, supporting resource circularity. It combines the natural appearance of real wood with the weather resistance and dimensional stability of plastic, overcoming the problems of traditional wood—cracking, warping, and mildew—while offering waterproof, insect-resistant, paint-free, and low-maintenance performance. It is suitable for both interior and exterior wall decoration.
