Tatajuba, also known as bagassa, is native to tropical South America. The Tatajuba tree is mainly found in Brazil and Guiana. It is one of the lesser known woods in the forests of northern South America.

With its high resistance (class 1) and relative hardness, Tatajuba is a hard-wearing decking wood. The wood color is a homogeneous yellow-brown with clear glossy stripes, which darkens strongly in the sun to a dark red-brown. The planed surface may have a slightly rough structure from alternating grain.

Tatajuba – The pioneer tree

The young Tatajuba tree differs significantly in appearance from the older tree. It was therefore previously assumed that there were two different species. Tatajuba belongs to the latex-producing wood species and can reach a height of 45 m and a diameter of up to 1.90 m at breast height.

Tatajuba, also known as bagassa, is a long-lived pioneer tree that establishes itself very quickly in forest areas destroyed by forest fires and in gaps left by dying trees, so-called succession areas.

Hard and resistant

With an approximate density of 1100 kg/m³ and a moisture content of 12%, Tatajuba, like Cumaru and Massaranduba, is one of the heavier woods. The hardness according to Janka is 7800 – 10000 N, the dimensional stability is good.

The low tangential and radial shrinkage rate of approximately 0.3 % tangential and 0.4 % radial and the durability class according to DIN-EN 350-2 of “Class 1” make Tatajuba a very suitable wood for construction and exterior use. The first classification states that Tatajuba is resistant to attack by fungi and wood-boring insects.

Despite its high density, the wood of the Tatajuba tree has only moderate shrinkage and is therefore easy to dry. Although the hardness according to Janka is very high, Tatatjuba can also be worked relatively well when subjected to high forces.

The ratio between stress and elongation, which results from the effect of the force on the elasticity of the wood, is specified for Tatajuba with an MOE of 21490 N/mm2 and the bending and compressive strength up to fracture, the MOR, is specified as 78 N/mm2.

Weak point delay

Due to the aforementioned positive properties, the high durability, the high resistance to fungi and insects, Tatajuba is also very suitable as construction wood for the substructure of terraces. The only moderate stamina is somewhat problematic. For this reason, the distance between the substructure of a Tatajuba terrace should not exceed 45 centimetres when building a terrace. Tatajuba is mainly used in construction, furniture manufacturing, outdoor flooring and boat building.
