For example a species grown in one country may have significantly different durability characteristics to the same species grown in another country. This may be due to more rapid growth, harvesting at an earlier age or to a lesser extent, differences in processing. Furthermore, similar species may have sub-species which could exhibit totally different durability characteristics.

Due care should be taken that any wood , Protect Your Floors With A Concrete Sealant! does not contain the outside , Three Excellent Low-Flow Showerheads sapwood. Sapwood of most hardwood species is non durable and will decay quite rapidly even if the heartwood itself is rated as highly durable.

This group includes a large range of species including Teak, Jarrah, Jatoba, Bongossi, Purpleheart, Selangan batu, Western Red Cedar, Merbau, Blackbutt, Spotted Gum, River Red Gum etc.

The third group, Class 3 is termed "Moderately Durable". Such species will give good service without preservative treatment if clear of the ground and used in conditions of low termite hazard and involving only intermittent wetting followed by reasonably rapid drying. Such timbers , Real Estate: Seller's Checklist can still be used for exterior decks , Are Sun Rooms Safe? but it would probably not be advisable to use such species in severe weather , Marble Fireplaces conditions unless a maintenance regime involving the application of good quality decking oil is carried out at regular intervals.

Finally and perhaps of lesser importance is that the lumber chosen should not twist, cup or deform in service.
