The ultimate in longevity and easy maintenance, opt for an elevated concrete deck cast in corrugated steel pan. A concrete deck is supported by a simple steel structure capable of long open spans. The steel frame can be fully trimmed out to give what is traditionally a commercial structure a warmth that can fit right in with any home's style.
The concrete deck surface can be enhanced with a stamped and colored pattern, coated with epoxy, or covered with a hard surface finish like porcelain tile or paver stone. Concrete decks have the added advantage of dry space below the deck. Elevated concrete decks do require professional engineering.
