Southeast Asian hardwood offering exceptional strength and warm tones
Batu (also known as Red Balau) is a premium Southeast Asian hardwood prized for its incredible density, strength, and rich reddish-brown color. Similar in performance to Ipe but often more affordably priced, Batu delivers outstanding durability and a beautiful, distinctive appearance that deepens with age. Its exceptional weather resistance makes it ideal for challenging climates.
