Advantages & limitations
Merbau
Advantages
- Rated for exterior exposure (EN 350 Class 1)
- Hard wear surface, dent-resistant
Limitations
- Hard on tooling; pre-drilling recommended
- Heavy — consider structure and handling
Indian Rosewood
Advantages
- Rated for exterior exposure (EN 350 Class 1)
- Hard wear surface, dent-resistant
Limitations
- Noticeable seasonal movement — allow for it in design
- Hard on tooling; pre-drilling recommended
- Heavy — consider structure and handling
Recommendation
Choose Merbau if…
- You need minimal movement (doors, decking, panelling)
Choose Indian Rosewood if…
- You need the harder wear surface
- Its profile matches the application better than a single overall score
Frequently asked questions
Which is more durable, Merbau or Indian Rosewood?
Neither — both carry the same EN 350 rating (Class 1, Very Durable). For outdoor decisions between them, weigh dimensional stability and hardness instead.
Which wood is better for outdoor use?
Merbau — outdoor performance combines decay durability with dimensional stability, and it leads on that combination.
Is Merbau harder than Indian Rosewood?
No — Indian Rosewood is harder (Janka 2440 vs 1712 lbf).
How we score. Each wood gets a weighted composite of the verified figures shown above: durability 22%, stability 18%, hardness 12%, bending strength 12%, machining ease 12%, stiffness 8%, flame spread 8%, lightness 8%. The Library Score is that composite's percentile rank within our 60-species library — 50 means the library median, 90 means it outperforms nine of every ten species we cover. No price data is scored — cost guidance is qualitative. The score summarises the data; it does not replace judgement about your specific application.
