Hardness Test

Someone asked me, how does hardness determine the durability of the wood?

The Janka Durability Test

The Janka Hardwood Durability Test is a method used to measure the stability and strength of specific Hardwood species. There are many differences between the various Hardwood species. While some of the species are hard, strong and dense, other species are light, smooth and soft. It’s extremely useful to know as much as possible about your next hardwood flooring purchase, for it can be vital information that helps you determine which species fits your specific needs and desires.

What does the number means, the smaller the score, the likelihood of the deck being dent by a simple hammer,
Pine Deck: 870 pounds. It is likely to get a dent.
Merbau: 1900 pounds
Borneo Ironwood: 3100 pounds.
Okan Ironwood: 3900 pounds.
Chengal: 2100 pounds.

It has been known that Okan ironwood is used by maritime explorers for Antarctica exploration shipbuilding.
whereby it has been able to last 10 years in sea water and extreme conditions, without any sign of rot. Maybe we can
try to do the same with Chengal timber, we should be seeing holes starting to form in less than 2 years.
