Best when…
- organic material benefits
Top advantages
- 01 organic material benefits
Top limitations
- 01 Very high density (1000–1100 kg/m³) — significantly heavier than radiata pine structural timber; increases dead load calculations and requires more robust connection hardware
- 02 Checking and splitting during seasoning — large-section members (100mm+) frequently develop surface and end checks as moisture content drops; design must accommodate or conceal checks in exposed applications
- 03 Limited availability of long lengths in structural grades — clear spans over 4.8 m in F14+ grades require ordering in advance; standard merchant stock typically 2.4–4.2 m
- 04 F-grade variability from visual stress grading — visual assessment per AS 2082 has ±20–25% strength variability compared to machine stress grading (MGP); specify MGP-equivalent where tight tolerances matter
- 05 Significant cost premium over structural softwood — $800–1500/m³ for F17–F27 Spotted Gum versus $400–600/m³ for equivalent MGP15 radiata pine structural
