Keruing – PEFC-Certified Heavy Hardwood for Commercial and Structural Applications

Keruing is a dense, durable tropical hardwood widely harvested across Southeast Asia. Known for its high strength, coarse texture, and reddish-brown to dark brown color, Keruing is commonly used where strength and wear resistance are key.

With a naturally oily surface and interlocked to straight grain, Keruing can be challenging to machine but delivers outstanding performance in demanding environments. Available as a PEFC-certified sustainable timber, Keruing supports environmentally responsible sourcing practices.

Supplied in custom dimensions, Keruing is available kiln-dried or air-dried based on project needs.
