Why Cumaru Decking?

Cumaru Decking provides a cost effective and long lasting decking alternative. Its colors are warm and attractive. Cumaru Decking also ages gracefully and lasts a long time for the owner.

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.
