What's on the poster
A species table covering Merbau, Kwila, Cypress Pine, Blackbutt, Spotted Gum, Tallowwood, Tasmanian Oak, Red Ironbark, Jarrah, Brushbox, Turpentine, Forest Red Gum, River Red Gum and Karri, among others.
Three reference tables: F ratings (stress grades F4 to F34), treatments (ACQ, CCA and LOSP), and bushfire attack levels (BAL-LOW to BAL-FZ).
How to read the poster
What each column means. For more detail, see understanding timber ratings.
- Common and scientific name
- Makes sure you select the exact species, as common names vary by region.
- Source and growing regions
- Where the timber comes from.
- Grain and colour
- Appearance, to help you picture the finished job. Timber is natural, so expect variation.
- F rating
- Stress grade: bending strength in MPa. Higher numbers are stronger. F14 or higher is recommended for decking, joists and bearers.
- Durability class
- Natural resistance to decay, from Class 1 (very durable) to Class 4 (non-durable). Match it to the exposure.
- H rating
- Hazard level: the exposure the timber suits, from H1 (indoors) to H6 (marine, in sea water).
- BAL rating
- The bushfire attack levels the species suits. Essential for designated bushfire-prone areas.
- Termite and ant resistance
- Natural resistance to these pests. Even resistant species should be part of an integrated termite management plan.
- Recommended treatments
- Whether the species needs preservative treatment, or whether oil finishes are enough.
- Typical uses
- Common applications where each species performs well.
