Ipe (Brazilian Walnut)

 S4S Eased Edge 1x4, 5/4x4, 5/4x6

This Brazilian species is one of the most stable of all the tropical hardwoods. It dries extremely well with little checking, twisting, or bow. It is widely recognized for its strength and natural resistance to decay. It can be used in ground contact applications without preservatives or additional treatments. The Forest Products Laboratory rates untreated Ipe hardwood, which is native to South America, as having an expected lifespan of 30 years or more. Widely used in commercial exterior construction such as boardwalks, piers, and benches it has recently become a popular choice for residential decks due to its low maintenance, attractive color, and extremely smooth surface that withstands the test of time. It is a heavy timber, weighing approximately 6 lbs. per board foot with a 12% to 14% moisture content, generally sinks in water, and has a fire rating of Class 1 UBC (uniform building code), the same as concrete or steel.  The strength rating (PSI) of Ipe is twice that of Oak, three times that of Cedar or Redwood, and ten times that of plastic.   Janka Hardness Scale rating: 3680 lbs.*
