About Bulletwood

Bulletwood (Massaranduba) is one of the hardest and strongest commercial hardwoods from the Amazon region. Its exceptional density, durability, and resistance to decay make it ideal for heavy-duty structural, marine, and exterior applications. The wood’s fine texture and uniform reddish-brown colour also make it suitable for high-end flooring and outdoor furniture. Bulletwood performs extremely well in harsh environments and is valued for its long service life.
