On the Janko scale, Birich is 1260 compared to Red Oak at 1290, White

That's interesting, as the bamboo flooring I've seen hasn't worn
anywhere near as well as everyday red oak.


That value for the bamboo is for the non-'carbonized' bamboo. The
chocolate brown stuff has been steamed to change the color and that
process significantly reduces the hardness of the material. Which is
why I went for the natural color in a Phillipines-harvested bamboo
which is noticeably darker than other bamboos. Course, they all
darken with exposure to light.

Strand woven Bamboo 3200
Natural Bamboo (represents one species) 1380
Carbonized Bamboo (represents one species) 1180

The hardness of bamboo also depends on when (years maturity) the bamboo
is harvested and what species of bamboo is used.

For comparing:
Cumaru / Brazilian Teak 3540
White Oak 1360
Red Oak (Northern) 1290
Black Walnut 1010
