Massaranduba (Manilkara Bidentata spp).
Common names include bulletwood, Brazilian redwood, or massa and is a wood of high density but will remain easy to work. Most often used as decking or flooring it does respond to steam bending better than most other Brazilian hardwoods. With a straight grain which can have an almost purplish hue this is a wood that has a distinctive look. Though its heartwood often is a shade of purple, Manilkara bidentata is sometimes confused with another tropical tree widely known as “purpleheart”. Our wholesale mill produces both FSC certified and non-fsc massaranduba. We have massaranduba in decking, flooring, dimensional lumber, E4E, S4S, RS (Rough Sawn), deck tiles, and table slabs.
