Wood Hardness Chart
The Janka hardness test measures the force required to embed a .444 inch steel ball to half its diameter in wood. It is one of the best measures of the ability of a wood species to withstand denting and wear. The higher the number, the harder the wood is. A rating is not in this chart for bamboo, as bamboo flooring varies greatly between different manufacturers products. For instance, the CFS Premium Green bamboo has a rating of 1380.
