Structural hardwood strong enough to handle a horses kick

Cumaru (Dipteryx Odorata) is a very dense, heavy and hard timber. This makes it ideally suited for use as an exterior structural timber where heavy exposure to the weather is expected.

JSC Cumaru (known as Tonka by others) is a 100% FSC certified timber product that is durable enough to withstand a horses kick - and was used at the recently redesigned Ellerslie Stables.

JSC regularly recommends and sources Cumaru for unique architectural projects. We have extensive experience working alongside your experts to help you design facades and structures that will last for generations.
