Detailed scientific and mechanical properties for Merbau Hardwood Lumber

Merbau

  • Description: Merbau is a beautiful exotic hardwood that grows in the forests of Southeast Asia as well as throughout the South Pacific region. When freshly cut the color of the wood is yellow to orangish-brown, but upon exposure will darken to a rich dark brown to reddish-brown color much like Brazilian Cherry. One unique characteristic of Merbau is the yellow flecks, or mineral deposits, which can be seen in many of the pieces. These flecks will become more subtle over time, but when initially finished the wood appears to be flecked with gold.
  • More Info: Merbau truly is a perfect exotic wood floor species for a number of reasons. Not only is it a great alternative to Brazilian Cherry, which has become harder & harder to acquire, not to mention somewhat expensive, but it has all of the properties you look for in a wood floor; beautiful color, optimum hardness, & outstanding stability. Nova USA currently imports Merbau in a Solid 11/16" x 3-1/4” & 5” width. The product is Clear grade with 1’-6’ lengths and is only available Unfinished.
