Janka Hardness Rating

What is the Janka Hardness Test?

The Janka hardness test measures the hardness of wood. It measures the force required to embed an 11.28 mm (0.444 in) steel ball into wood to half the ball’s diameter. This method leaves an indentation. It is a good measurement technique to determine the ability of a type of wood to withstand denting and wear. It is also a good indicator of how resistant it is to sawing and nailing.
The results are stated in various ways, which can lead to confusion, especially when the name of the actual units employed is often not attached. In the United States, the measurement is in pounds-force (lbf). In Sweden it is in kilograms-force (kgf). Here in Australia, either in newtons (N) or kilonewtons (kN). Sometimes the results are treated as units, for example “660 Janka”.

As you can see from the Janka Hardness test below Genesis Bamboo comes in at 14.6 KN. This is a much harder than most common hardwood floors sold in Australia. Our flooring is on average 22% harder than Spotted Gum and 140% harder than Tasmanian Oak and is ranked among the hardest woods in the world.
This makes Genesis Bamboo Flooring the perfect fit for a busy modern Australian lifestyle.
