On Woods

I'm building a web site for a flooring company and part of wood flooring is how hard it is. The information below might be of use.

The Janka hardness test measures the force required to embed a .444 inch steell 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. By the same token, it is also a good indicator of how hard or easy a species is to saw or nail. Northern red oak, for example, has a janka hardness rating of 1290. Brazilian cherry, with a rating of 2350, is nearly twice as hard.
