Another product I used to sell and install that hasn't been discussed is vinyl. The decks I constructed used a treated frame (CCA at that time). The decking was attached with a hidden fastener system that involved aluminum "tracks" fastened to the joists with stainless screws. A dead blow hammer is used to smack the deck boards in place, not ridgedly attached to facilitate expansion and contraction. The railing was vinyl and reinforced with galvanized steel channel. All exposed joists are wrapped in vinyl fascia cover. The first one I built was ten years ago and it looks as good today as it did when it was built and the lady who owns it loves it. It was expensive, but of the highest quality in my book.
