COOWIN has focused on WPC (wood plastic composite) for 100 years. Their WPC decking and cladding products use patented composite technology to achieve fine looks that last through time. Their unique closed surface technology provides superior stain resistance compared to traditional composite or wood decks. COOWIN's 3D embossing technology creates a wood grain depth of 1mm that does not fray over time, providing a strong, textured surface like carefully carved artwork.
