KERUING DECKING TIMBER

Timber Qualities

Keruing timber, derived from several species within the Dipterocarpus genus, is a versatile hardwood native to Southeast Asia. Known for its strength and durability, Keruing has a reddish-brown to dark brown colour and a coarse texture with an interlocking grain. It is commonly used in heavy-duty applications such as flooring, decking, and outdoor furniture, as well as in the construction of bridges and railway sleepers. Its natural resistance to wear and tear makes it ideal for high-traffic areas. However, like many tropical hardwoods, it is crucial to source Keruing from sustainable suppliers to mitigate environmental impact and ensure long-term availability.
