Ironbark - (Red & Grey)

Specie Properties  -  read in conjunction with the General Notes

01. Common Name / s

Ironbark - (Red & Grey)

02. Botanical Name

Eucalyptus Paniculata

03. Primary Origin

Northern NSW and Southern Queensland

04. Colour & Figure

Light grey or light chocolate with occasional darker reds and browns occurring.

Other colours may occur in timbers grown in regional areas with some having black narrow and broad streaks running through the grain. Sapwood is distinctively lighter than the heartwood.

Important Note  -  Ironbark Colour – there are many botanical variants of the Ironbark species and in most cases, the adopted common name for each does not truly reflect its inherent colour characteristics. The well respected “Bootle” publication refers to the colour of heartwood of Grey Ironbark as “variable from pale to dark brown and including dark red”, and while his colour description for Red Ironbark is “Dark Red”, it is well known and accepted that light & medium red tones also prevail.

While specifiers may choose to nominate Ironbark requirements by specie name, control over colour variations is not possible and in all cases, the supply will reflect the natural colour variations yielded by the feedstock.

Figure – texture is moderately coarse and even, usually straight grained and only occasionally interlocked.

09. Grade Options

Standard & Better – the most common and economic grade available, includes
a range of the most interesting and moderate naturally occurring features.

Select – a grade supplied where appearance is of primary importance, this grade provides a low level of natural features which may limit supply, particularly of dressed widths exceeding 140mm             

10. Leaching

Leaching of extractives may occur although less than in some other hardwoods

11. Thickness
  (finished dressed)

Given some of the sawmilling supply constraints Timbeck has to deal with the chosen finished thickness of Dressed and Moulded products is 12-18-30-40mm

Thicker sections are available unseasoned

12. Width
  (finished dressed)

Widths from 18mm to 290mm are normally available

13. Length

Lengths are available in reasonable quantities from 0.9m to 4.2m however longer lengths from 4.5m to 6.0m have some supply limitations.

Set lengths when available are supplied in 300mm increments.


14. Price Guide
 

Relative Cost - 215 Units  (compared to Western Red Cedar at 100 units)

15. Coating
  (external)

Ironbark is usually supplied raw for on-site finishing however Timbeck has the capabilities to factory pre coat utilising Cutek CD50 clear oil.

Film forming Lacquers are not recommended for weather exposed applications.


16. Coating
  (internal)

Factory pre coating can be offered in UV cured lacquer for non-hard wearing areas, spray applied two pack polyurethane for hard wearing applications or oils for other applications.
 

17. Availability

Not as readily available as some other hardwoods particularly in relation to the supply of volumes of set sizes and specific lengths of seasoned sections. Extended lead times may be necessary to ensure supply meets expectations.
