There are composite products out there that require no maintenance, include recycled materials, and look great. The only thing is some of them require 12 or 14" floor joists instead of 16" on center, because they flex more than wood. That doesn't mean they won't last as long, on the contrary; but most folks won't like the flexing that occurs with Trex or some of the other composites out there. The big box stores (Lowe's, Home Depot, etc.) often carry ads for materials in weekly circulars; I bet if you went to their websites they would have what they carry and some info about each, or at least the mfr. name so you could look it up. They come in lots of colours nowadays, too. If I had my druthers, I would have recommended it to my friend up north, he has a huge deck that goes 3/4 around his house, plus stairs.
