The Janka Hardness Scale is an industry standard for measuring how durable various wood species are — and more and more consumers are looking to it to make their buying decisions. And while this example lists just some of the most popular hardwood species, there are hundreds of varieties, representing the North American hardwood population. Larger force - harder wood.
