Timber species used must have robust mechanical properties and high to very high natural durability, depending on the structures' degree of exposure to weather. Appearance is a secondary selection criterion.
As tropical timber is naturally resistant to decay, fungal and insect attack and ecologically the right choice, it is recommended for heavy use, such as hydraulic works or industrial flooring.
Such applications involve a range of technical requirements that typically require the use of large sections in the form of beams, planks and battens.
