Check out www.evolution-deck.com, which is made from galvanized steel with granite stone - our house is featured. This cost us about 25% more than a composite deck installed. Regardless of brand, a wood or composite deck requires maintenance, deteriorates, and doesn't last more than 15 years. Evolutiondeck provides a true 30-year warranty, doesn't require maintenance and it adds to the resale value of our home! We saw this as a worthwhile investment.
