WPC (Wood Plastic Composite) is a composite material made of wood fiber and thermoplastics. It is widely used in various applications, including wall cladding, benches, and decking.

WPC hollow decking refers to WPC decking boards or planks that have a hollow core structure. These hollow boards are lighter in weight compared to WPC solid decking but still offer good strength and stability. WPC hollow decking is often used in outdoor applications such as decking for patios, balconies, or decks around swimming pools. The hollow core design helps to reduce the overall weight of the decking while maintaining its structural integrity.
