Cumaru Decking

First Class Performance & A Great Value

Cumaru (aka Brazilian Teak, Dipteryx Odorata, Almendrillo, Tonka, and Tonquin Bean) creates that carefree, inviting outdoor space you crave. When you step onto a deck made of Cumaru, you'll be presented with a rich display of golden tan to reddish brown colors and dark grain accents. Cumaru is an exotic hardwood you can count on because it naturally resists rot, decay and insect attack. Check out how Cumaru compares to ipe, teak, and composite decking.

Cumaru decking is the second hardest decking we sell. In Brazil, Cumaru is used in mansions, five-star hotels and major commercial projects. It has a 50+ year lifespan without preservatives!  Our Cumaru decking is responsibly harvested from managed forests to provide a truly renewable resource. Cumaru has many benefits over teak and is available at a fraction of the cost. We ship our Cumaru decking products direct to your home or job site.
