Cumaru, a beautiful hardwood, is very much similar to Ipe in colour, durability and strength. The decking is KD (kiln-dried) to 16% M.C. for increased stability. It is pre-grooved for assembly with EBTY hidden deck fasteners. The profile is reversible, smooth one face and small anti-slip grooves on the other, providing the option to choose preferred surface - and make attractive designs.
