Cumaru Decking
About Cumaru Wood
Cumaru, also known as Brazilian Teak or Golden Teak, is a naturally durable Brazilian timber with a density similar to Ipe. Its consistent golden brown color and moderate cost make it an attractive alternate to more expensive hardwoods such as Teak or Ipe. Cumaru is resistant to rot and decay, making it an excellent choice for exterior applications such as decking. It not only lasts a long time, but has the beauty of an interior hardwood. It outlasts other popular wood decking species such as treated Pine, Cedar, Redwood and Douglas Fir.
ETT stocks standards Cumaru decking (Brazilian Teak) sizes, and offers custom millwork for special profiles or sizes. Cumaru deck facing is partially air-dried (AD), and then kiln-dried (KD) to approximately 15% moisture content for stability. ETT also stocks all the accessories – fasteners, sealers, cleaners, and finishes – to complete your deck
