With its ‘capped’ design creating a protective layer that offers maximum protection against stains and the elements for an extra long life. HD Deck® Dual takes composite decking to the next level. HD Deck® Dual is made from FSC® 100% hardwood flour and recycled plastic which combine to produce a high quality finished product that outperforms traditional treated timber.
