Harder than Hardwood

The Jenka Ball Hardness Test measures the force required to drive a 11.28mm (.444 inch) steel ball half its diameter into a piece of wood.

The test is a good indicator of resistance to denting, as well as its hardness for nailing and drilling. The higher the number, measured in kilogram-force (kgf), the harder the species.

Bamboo flooring is stronger, denser and more stable than many hardwoods. It is 13% harder than maple, 27% harder than northern red oak and is also 99% termite safe. It expands and contracts 50% less than timber and endures heavy traffic, spills and even pets.

Bamboo is an enviromentally friendly and ecologically sustainable product that is becoming increasingly popular amongst cultures worldwide.
