Tatajuba –(Bagassa Guianensis)
Tatajuba also known by a few other names such as cow-wood, Amarelao, or Bagasse. It is another hardwood that has not been prevalent in all international markets. Tatajuba has characteristics similar to that of Ipe and Cumaru. It could be a good alternative to budget-conscious clients. Tatajuba is not as difficult to work with as Ipe or Cumaru. The color ranges from golden to reddish brown. Fresh cut Tatajuba appears yellow, which is close to yellowheart but darkens over time. It is available as FSC certified and is kiln-dried (KD). We have Tatajuba as decking, flooring, dimensional lumber, E4E, S4S, RS (Rough Sawn), deck tiles, and table slabs.
