Garapa is a very easy-to-work-with timber considering its density as a South American hardwood. It is a durable and stable timber.
Garapa has a distinct golden yellow brown colour, which has a reflective streak within – often resembling the same as that of a cat’s-eye gemstone. The colour often naturally weathers to a grey tone with age. The grain is usually straight but can tend to be interlocking with a consistent medium texture.
20 – 30m
1 000 – 1 500mm
Average Dried Weight:
1,8 – 4.8m (300mm intervals)
19 x 90mm
21 x 140mm
Garapa is arguably one of the best decking timbers on the South African market and much loved by decking contractors. It is often overlooked by clients because of its yellow appearance, however over time – like many of its counterparts – it will turn grey if left to weather.
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.
It scores fairly well in this department although it is nowhere close to as dense as Massaranduba or Cumaru.
It is quite a dense timber coming in at very similar weight to timbers such as Rhodesian Teak.
Modulus of Rupture
A very respectable figure for decking. It is not easily broken but again does not have the structural strength that you would expect from Cumaru or Massaranduba.
This timber will not easily distort. It is known for its stability in our market and if your frame is built correctly, you should have no issues with boards twisting or bending our of shape.
Shrinkage and T/R Ratio
Although officially considered to be of “average” stability, the timber is well known for performing well in a variety of environments from the coast to the Lowveld.
