Tanalised timber refers to wood that has been industrially treated using a controlled vacuum pressure process with the Tanalith preservative.
Tanalith C preservative contains chromated copper arsenate. In Europe, the use of Tanalised C pressure treated timber was restricted in 2006, and its successor in this market is Tanalised E pressure treated timber, which contains copper and triazole biocides.
Timber treated with any Tanalith preservative is resistant to leaching but should be handled with care and any exposed skin is recommended to be washed before eating, drinking or going to the toilet. Avoid handling treated timber that is wet.
See the Related links for more information.
