| Name | Jarrah (Eucalyptus marginata) |
| Type | Hardwood. |
| Other Names | Also known as Eucalyptus. |
| Sources | Grows in south western Australia. |
| Appearance | Typically straight grained but often interlocked and wavy. Moderately coarse, even texture. Rich dark reddish brown heartwood, often with gum veins and boat-shaped flecks. Paler reddish brown sapwood. |
| Physical Props | Heavy, hard, strong (particularly crushing strength), and stiff with moderate dimensional stability in service. Highly decay resistant heartwood. Steam-bends moderately well. |
| Working Props | Fairly difficult to work due to hardness and density. Reduced cutting angle recommended for planing. Turns well. Pre-drilling required for screwing and nailing. Glues and finishes well. |
| Uses | Used extensively for construction in Australia, particularly for marine applications such as bridges, dock pilings, wharfs, and ship building. Also used for flooring, cross-ties, shingles, siding, trim, rafters, joists, furniture, interior joinery, chemical vats, and decorative veneers. Valued for striking tool handles. |
| Comments | More jarrah is harvested than any other commercial Australian timber. It is more appropriate than Karri for marine applications but it’s not quite as heavy or as strong. |
