Origin & character of the wood
Keruing comprises numerous species from the genus Dipterocarpus, which are native to the tropical forests of South East Asia. The trees produce a hard, heavy wood that is particularly suitable for technically demanding applications. Due to its high strength, Keruing is particularly valued in the commercial sector.
Structure with powerful radiance
Keruing shows a color spectrum from reddish-brown to dark brown, often accompanied by distinctive resin channels. The coarse pores give the wood a robust appearance and make it a reliable material for construction projects. You can find information on the durability classes here.
Strong wood for hard-wearing applications
Thanks to its high density and stability, Keruing is particularly suitable for decking boards, constructions or vehicle floors. The wood remains dimensionally stable even under high loads. You can find other relevant terms and types of wood in the Betterwood lexicon.
