Teak

Tectona grandis Linnaeus Fm. Lamiaceae

Our Plantation Teak have an excellent quality and density. Heavy, resistant and very durable. A little oily to the touch. Great natural durability and dimensional stability. Antiseptic resin that makes it resistant to the attack of termites, acids and fungi.

Teak Uses

Boat construction, indoor and outdoor furniture, carpentry, joinery, railway sleepers tracks, floors, vehicles parts, musical instruments, sporting goods, toys, packaging, tanks, cooperage, drawers, decorative plates, posts (for construction, for transmission and for fences), handles for tool implements, turnery, crafts, pilings for bridges, firewood and coal, agricultural implements and wagons. It is optimal for outdoor, being able to adapt to extreme weather conditions.
