Composite decking is a board made of wood-polymer composite (WPC). The primary components of composite decking are wood flour and polymer resin. Composite decking exhibits high resistance to wear and the impact of adverse external factors, making it suitable for use as a surface covering in outdoor areas, such as patios, terraces, poolsides, balconies, and so on. Composite decking can be solid and hollow. Solid composite decking is more durable and is recommended for use in high-load areas.
