Cumaru Decking

Advantage Cumaru Decking offers unmatched versatility.

Cumaru (a.k.a 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.

Beware of Shady Sellers

Some unscrupulous lumber companies charge hidden extra fees, ship low-grade material, and source their wood from unethical mills. Here are some questions to ask when buying your lumber:

  • Where is the material shipping from?
  • Has the seller actually seen the wood they're selling?
  • Can you visit their warehouse?

Our lumber is sustainably sourced directly from well managed forest and custom milled with our own machinery. We have a huge inventory that you’re welcome to visit any time, and we work with the wood ourselves, so we can guarantee its quality. We don’t charge extra insurance or packaging fees—we cover those for you!

In short, if a deal seems too good to be true, it probably is. Learn more about how to avoid bad lumber companies.
