We built this deck with TimberTech XLM (extreme low maintenance) series decking which is class "A" fire rated. There are no seems on this deck. It is scratch resistant and comes with a 25 year warranty. We built a Stone Deck in the middle and had it piped for a gas fire pit. Hidden fateners add beauty to your deck and we offer a free up grade to hidden fasteners (hidden screws) on all TimberTech decks.
