3D Embossed Circular Hole WPC Base Decking Board – Dark Grey

Some composite decking boards are content to just look like timber. The 3D Embossed Circular Hole WPC Decking Board in Dark Grey takes a different approach — it uses a distinctive embossed surface profile and a vented circular-hole structure to deliver real, measurable performance advantages that go beyond aesthetics.

The 3D embossed surface isn’t decorative texture for its own sake. The raised grain pattern provides genuine slip resistance — a measurable improvement over smooth-faced composite and flat timber boards, making this one of the smarter choices for pool surrounds, alfresco areas, and any deck surface that sees regular wet-foot traffic. The texture also does an effective job of breaking up light reflection, giving the Dark Grey finish a more natural, matte depth rather than the plastic sheen that gives cheaper composite boards away.

The circular hole profile along the board’s underside serves the structural purpose of reducing board weight without compromising strength, while also improving airflow underneath the deck. Better ventilation under the deck means less moisture accumulation and faster drying after rain — both of which extend the life of your subframe and reduce the conditions that encourage mould growth.

At 149mm wide and 22mm thick, this is a full-sized board with the structural depth to handle standard joist spacings of up to 400mm and the foot traffic demands of a busy entertaining area. The 5400mm board length keeps your join count low across most standard deck widths.

No oiling. No sealing. No sanding. Just a hose-down when it needs it.
