Overview
What this timber is.
Eucalyptus camaldulensis is known for red to reddish-brown heartwood. In Cape Town it is discussed as a local hardwood option for decks and exterior work, distinct from sugar gum and from plantation grandis.
Decking timber
Red river gum for Cape Town decking.
Red river gum is a eucalypt with distinctive red heartwood, grown in South Africa and used for outdoor timber when suitably processed.

- Botanical name: Eucalyptus camaldulensis.
- Eucalyptus camaldulensis — red heartwood.
- Local hardwood option, not an imported tropical species.
- Colour fades and greys in weather; can check in sun.
- Board quality and drying decide whether it is suitable as decking.
Our approach
Suited environment.
Considered for Western Cape outdoor floors and structures where a red eucalypt is wanted and the boards are dry enough for the job. Full sun and wide boards increase movement. Coastal metal still has to be specified.
What it is
The colour is the reason many people ask for it. Density and gum vein, drying quality and board stability vary with the stock. It is still a eucalypt: it can move, check and weather. It is not a tropical hardwood and it is not treated pine. Deckspertz does not publish a lifespan, a rate card, or a maintenance-free claim for this timber.
Suited environment
Inland Cape Town, northern suburbs and the Winelands are typical places this timber is discussed. A wet, shaded courtyard or a salt-sprayed Atlantic deck is a harder brief — possible only with the right grade, gaps, ventilation and fasteners. Do not assume furniture-grade colour outdoors.
What happens over time
The red heartwood dulls and then greys on faces that see weather. Oils deepen the red while they remain. Checking along the grain is common on eucalypts in Cape UV. Adjacent pale masonry can pick up colour from extractives when the timber is new and wet.
How Deckspertz specifies it
Red river gum is included as a Cape Town decking conversation, not as a named completed-project timber on this website at the time of writing. Moisture content, profile and finish are specified from the site. Supply in Cape Town changes. This page is a species guide, not a stock list.

Questions
Before you enquire.
Will it stay red?
Not if it is left to the weather. Coatings hold colour for a time. Uncoated red river gum greys like other outdoor eucalypts.
Is it the same as red grandis?
No. Red river gum is E. camaldulensis. Red grandis is typically E. grandis.
Start a project
Specify timber from the site, not a catalogue name.
Share the suburb, how the outdoor floor will be used, and photographs if you have them. Availability of Red river gum is checked for the job.
