Andaman Padauk
Pterocarpus dalbergioides
Also known as: Andaman Redwood, Indian Padauk, Vermillion Wood
Andaman Padauk is a striking Southeast Asian hardwood endemic to the Andaman Islands, valued for its vivid brick-red to golden heartwood and high natural durability. A member of the CITES-regulated Pterocarpus genus, it is closely related to African Padauk and shares many of its working characteristics, producing a bold visual impact in furniture and architectural millwork.
Botanical Profile
Pterocarpus dalbergioides is a large deciduous tree of the Fabaceae family, native to the Andaman Islands in the Indian Ocean. It reaches 30–40 metres in height with a broad crown. Like other Pterocarpus species, it yields a distinctive red sap — historically used as a dye — and produces winged seed pods.
Physical Properties
Diffuse-porous hardwood with medium to coarse texture and air-dried density of approximately 770 kg/m³. Janka hardness of 1,720 lbf. The heartwood is initially vivid red to golden-orange; UV exposure causes significant colour shift to a warm reddish-brown. Tangential shrinkage 5.5%, radial 3.5%.
Workshop Notes
Blunting Effect
Moderate — silica deposits can accelerate edge wear
Gluing Advice
Good adhesion; oily surface may require solvent wipe before bonding
Finishing
Finishes well; UV-protective coatings recommended to preserve colour
Steam Bending
Moderate steam bending properties
Historical Context
Andaman Padauk was extensively harvested during British colonial administration of the Andaman Islands from the 18th century onward, used for ship building, railway sleepers, and structural timber. Its distinctive colour made it prized for decorative furniture exported to mainland India and Europe. Regulated harvesting and CITES listing now constrain commercial availability.
Technical Specs
Golden to brick-red heartwood, often with darker streaks; fades to reddish-brown over time with UV exposure
