Yes, it does. Both species are extremely dense with life expectancies in the decades. Both are more durable than traditional wood species like Cedar, Pine or Redwood. They can withstand the punishment of patio furniture, pets, and barbecues better than softwood because they are denser. Champagne Ipe also performs very well outside. If left untreated, it will fade to a silvery-gray color as it oxidizes. The alternative would be to use a coat of oil based stain like Penofin or SuperDeck to help maintain the natural beauty of the lumber.
