Red Bloodwood (Corymbia Gummifera)

Red Bloodwood is a medium sized Australian hardwood occurring along the coast of New South Wales and Queensland. It is commonly used in the production of round timber.

Red Bloodwood is a medium-sized Australian hardwood that grows along the coastal areas of New South Wales and Queensland.

Taking its common name from the appearance of its heartwood, Red Bloodwood ranges from a dark pink to dark red colour, with much paler sapwood. It has a course texture, with the grain of Red Bloodwood usually interlocked.

Due to the presence of concentric gum veins, Red Bloodwood is not ideally suited for use as sawn timber as gum veins – or the red-coloured kino veins – can open up during drying. This species is mainly used for round timber applications such as poles, piles and posts, however due to its attractive grain pattern, Red Bloodwood is also used for veneers and decorative paneling.

Red Bloodwood can be painted, stained and polished. It glues satisfactorily, but any surface preparation or machining should be done so immediately prior.

A highly durable and dense species, Red Bloodwood is well suited for in-ground applications such as posts, although untreated sapwood is susceptible to lyctid attack.

Sydney Blue Gum is a moderately durable timber with a life expectancy for in-ground applications of between eight and 15 years. Untreated sapwood is susceptible to Lyctid borer attack.

Sydney Blue Gum timber is easy to dry relative to most other eucalypts. It is also easy to work, dress and fix. It responds well to most finishes and takes a good polish, making it popular for decorative applications where moderate durability is required.

Type:

    Hardwood

Appearance

Red Bloodwood ranges from a dark pink to dark red colour, with a much paler sapwood. It has a course texture, with the grain of Red Bloodwood usually interlocked. Concentric gum veins, or kino veins, feature prominently and make this an attractive feature for decorative veneers and paneling.

Common Applications

While the presence of concentric gum veins is an attractive feature for decorative veneers and paneling, this also limits the other applications of Red Bloodwood to round timber. Poles, piles and posts are the most common and red bloodwood’s high durability makes it well suited for in-ground applications. Red Bloodwood can also be used for sleepers, fencing and house stumps.

Common Form

Sawn, Veneer

Workabiity

Red Bloodwood can be painted, stained and polished. It glues satisfactorily, but any surface preparation or machining should be done so immediately prior. The presence of concentric gum veins means Red Bloodwood is rarely used in sawn timber form – mainly round timber and decorative veneers or paneling. Red Bloodwood can be seasoned satisfactorily, however there is a tendency for the gum veins to open up during the drying process.

Fencing

When it comes to fencing, timber is your natural choice. A material that is durable, strong and reliable it compliments almost every outdoor landscape and environment. Clear specification, detailed installation and appropriate maintenance will see any timber fence provide a natural and lasting property boundary and back drop for years to come.

Internal Panelling

Timber paneling creates interiors as warm as they are stylish. Commonly utilising an MDF or plywood substrate, internal timber paneling is natural and versatile and comes as either solid natural timber panels or as sheets of engineered wood products

Structural Timber Posts

Timber poles are utilised in structural construction to provide support for gravity loads and resistance against lateral forces. Not only serving a structural function, timber poles provide many aesthetic benefits, with their use in construction often complementing architectural designs aimed at harmonisation with the natural environment.
