It is an easy to work, and is a moderately durable timber that finishes well. Eucalyptus Resinifera has much the same aesthetic look in colour and grain as it’s common relative genome Eucalyptus Grandis, but unlike it, it has a higher density; which is why we choose this as preference.
The colour of Saligna varies from dark pink to reddish brown with a paler sapwood which is easily distinguishable. Saligna has a moderately course texture and the grain is typically straight with occasional interlocking.

Average Dried Weight:
1,2 – 3m (300mm intervals)
22 x 100mm
Grown in South Africa as a structural timber, Saligna is now used for everything from doors and windows, to decking, flooring and furniture. It is a level up from Pine and for its price, offers a good entry level hardwood deck. It is important that this material is dried correctly, as it is not known for its stability.
Timber is an organic product, as such, many people don’t realise that timber performance can be measured and averaged. These numbers are well documented and accessible to the consumer. They can tell you all you need to know about what to expect from a particular timber. We believe your choices should be based on fact and not perception or “hear say”. To make it easier to decipher these numbers, we have placed a table below that compares the various hardwood decking timbers On The Deck supplies. We then decipher what each analysis effectively means to your particular project.

Timber being a natural and organic material means that each and every species is different and has unique properties which makes them suitable for a range of different applications and uses. We have simplified the main properties that are measured and put it into an easy to read and simplified version so that the numbers relate back to how the timbers perform.
Although not as high as some of the other common hardwoods, it is still reasonably dense though and won’t mark too easy. It will not dent too easily.
An average for this species is around 650kg/m3, but in some cases certain hybrids can push up to 850kg/m3.
Modulus of Rupture
This is very good for this timber and you can see what it is an excellent structural timber.
It won’t distort easily and holds it shape fairly well, so long as it is correctly secured.
Shrinkage and T/R Ratio
It is not known for stability and in some cases probably gets more critical reviews than it deserves. The timber as mentioned above needs to be correctly dried and lengths not exceeding 3m should be used.
