Tectona grandis
Teak (Tectona grandis) is a medium-hardness wood balancing workability and wear resistance, with a Janka hardness of 630 lbf (2802 N) and a density of about 0.55 g/cm³. It originates from india and south asia.
With radial shrinkage of 2.6% and tangential shrinkage of 5.3% (a T/R ratio of 2.04), it is moderately stable — allow for seasonal movement in wide boards. Its fiber saturation point is around 28%, below which the wood begins to shrink and move as it dries.
These figures feed directly into the Vriksai calculators below — select Teak in any of them to get species-specific results for weight, moisture, shrinkage and hardness.
