WPC No-Gap Composite Decking Board, 144 x 5.7 x 0.9 In., Dark Grey

The B-D1-DG is a Dark Grey WPC (Wood Composite Polymer) no-gap composite decking board measuring 144 x 5.7 x 0.9 in., designed for exterior decking applications in residential and commercial settings. It is manufactured using co-extrusion technology, in which a protective polymer outer layer and a high-density recycled plastic and wood fiber inner layer are processed simultaneously, resulting in 360-degree surface protection. The outer polymer coating provides UV resistance, anti-scratch and wear resistance, stain resistance, and a slip-resistant 3D wood grain texture. The no-gap profile eliminates the open joints found in traditional decking systems. The board carries a waterproof environmental rating and a 25-year rated service life. Installation uses a patented side-clip system compatible with standard decking joists; no face screwing is required. The manufacturer states a 5-year product warranty. CE, SGS, and ISO certifications are listed in the datasheet; however, specific certification numbers and scope have not been independently confirmed. Buyers requiring documentation should request copies prior to specification.
