Red Grandis – Eucalyptus Grandis
Red Grandis is a straight grained hardwood timber of the Eucalyptus family. Sourced from Uruguay, it is a fast grown hardwood and it is harvested at around 20 years old when it has reached a diameter of around 60cm.
The trees are tall and straight giving it a good straight grain and the forests are well managed and regular pruning ensures there are minimal knots.
Red Grandis has full FSC certification and is a very stable and dense timber with a durability class of 3 meaning that untreated it is rated as moderately durable.
As this species is only rated as moderately durable we would recommend if being used externally it is pressure treated to protect the sapwood from rot and insect attack.
We would recommend Microshades High pressure treatment by Brookridge Timber which would give the product a 30 year warranty against rot and insect attack and increase the durability class to 2 which is rated as durable.
