Eucalyptus (family Myrtaceae) is a very large genus, and timber properties vary widely by species. Two of the most commercial are Eucalyptus grandis (rose gum), with a dried density around 640 kg/m³ and a Janka hardness of about 1,260 lbf, and Eucalyptus globulus (blue gum), which is much denser at roughly 820 kg/m³ and very hard at about 2,370 lbf. Across the genus, density can range from about 450 to over 1,100 kg/m³, so eucalyptus should always be specified by species.

Eucalyptus grows exceptionally fast in managed plantations, but in its natural state it is difficult timber: it is prone to high shrinkage, in-service movement, drying stresses, and surface checking, and some species are susceptible to insect and termite attack. BFP Thermo® Eucalyptus is heat-treated at approximately 180–220 °C in a low-oxygen atmosphere, which substantially reduces its moisture uptake and movement and deepens its colour to a uniform caramel-brown through the section.

The most reliable benefit of modifying eucalyptus is this gain in dimensional stability. Improvements in decay durability are real but species-dependent, and are strongest at the top of the temperature range — so for exterior work we advise selecting species and grade to suit the exposure rather than assuming all eucalyptus performs alike.

Its natural density gives thermo eucalyptus good wear resistance for flooring and decking, and its warm, tropical-looking tone suits premium cladding and outdoor furniture.

As a trusted timber importer in India — where eucalyptus is widely plantation-grown — we produce eucalyptus in decking and cladding profiles to order. Clients comparing thermo eucalyptus wood price against imported tropical hardwoods often value its combination of hardness and renewable, locally available supply.
