Ipê, Cumaru and Massaranduba are species of hardwood coming from South America. They are exceptionally durable outdoor hardwood decking materials and proven to withstand the elements (think Atlantic City Boardwalks). They all have excellent resistance to mold, termites and decay and over time, all weather to a gray patina. They can be used in a variety of applications from hotel rooftop pool decks to boardwalks, shared condo terraces, outdoor dining spaces for restaurants and bars and more. While there are slight variations in their Janka rating and grain, the differences really comes down to initial color and aesthetics.
