Slate Grey SmartBoard Composite Decking 20mm x 138mm x 3600mm

Slate Grey SmartBoard composite decking board, finished size 20mm × 138mm × 3600mm. A reversible board with a brushed matt finish on both faces — smooth one side for a clean modern look, reeded on the reverse to echo traditional timber decking. The deeper, cooler grey tone sits between Battleship Grey and a charcoal finish and reads particularly well alongside rendered or painted walls. Manufactured from 90% recycled material and backed by a 25-year manufacturer’s residential warranty. Will not rot, split or crack, and qualifies as low slip risk under UK HSE testing. Must be fixed using the 63mm SmartBoard colour-matched decking screws (sold separately). Sold per 3600mm board.
