WPC Co-Extruded No-Gap Decking Board 144 x 5.7 x 0.9 In. Walnut

The B-D1-WL is a co-extruded WPC (Wood Composite Polymer) no-gap decking board in a Walnut finish, designed for exterior decking applications. Each board measures 144 in. x 5.7 in. x 0.9 in. and is produced using a high-tech co-extrusion process that bonds a protective polymer outer layer with a high-density recycled plastic and wood fiber inner core simultaneously. The outer polymer layer provides 360-degree protection with UV resistance, anti-scratch and wear resistance, stain resistance, and a 3D wood-grain texture with slip resistance. The product carries a waterproof environmental rating and a fire retardant construction, with a rated service life of 25 years. The no-gap design eliminates standard board spacing, reducing trip hazards and preventing loss of small objects through the deck surface. Installation uses a patented hidden side-clip system requiring no exposed fasteners on the board face. The manufacturer states a 5-year warranty on this product. CE, SGS, and ISO certifications are listed in the datasheet; however, specific certification numbers and scope have not been independently confirmed in the provided source data.
