A few good wood types for decks are southern yellow pine, ipe, cambara, cumaru, red balau, and golden ironwood. Redwood, red cedar and Port Orford white cedar are also good woods for decks. These woods are dense, resist insects and can stand up to weather.
Teak is also an excellent wood to use for decking. It is such a tough and durable wood that it is used for the decking of ships. Unlike other woods, it does not even need to be sealed to prevent it from rotting or warping. Like other woods, it will simply weather to a silver gray. However, a homeowner who wants her teak deck to retain its reddish-brown color can treat it.
