Cumaru embodies the appeal of plain wood. Known for its consistent coloring, the South American hardwood is as strong as ipe, and kiln drying ensures stability. The FSC-certified product is available either unfinished or prefinished, in lengths up to 20 feet and a variety of decking widths. It also has a Class A fire rating and 25-year warranty.
