5/4x6 Accoya One Sided Pre-Grooved decking combines the natural beauty of real wood with outstanding durability, stability, and installation efficiency. Designed for use with hidden deck fasteners, the one sided pre-grooved profile creates a clean, fastener-free deck surface ideal for high-end outdoor living spaces.

Accoya wood is engineered to resist swelling, shrinking, rot, and insect damage, making it an excellent choice for decks in humid climates, coastal environments, and demanding exterior conditions. Its exceptional dimensional stability helps boards remain flatter and more consistent over time compared to many traditional wood decking materials.
