Worldwide Hardwoods

We frequently supply a range of constructional and marine hardwoods such as iroko, keruing, ekki (azobe), opepe and balau. These timbers are widely used for external applications such as street furniture, claddings, lorry bodies and sea/river defences. Both sawn and planed finishes are available with additional machining such as profiling, pointing and drilling etc.

Keruing (Dipterocarpus)

Density approx. 880kg/m3 - Malaysia

Product Size Finished Size Grade Heat Treatment Environmental Scheme
26 x 150mm plus or minus 1-2mm Select & better WET PEFC
38 x 150mm & wider plus or minus 1-2mm Select & better WET PEFC
50 x 150mm & wider plus or minus 1-2mm Select & better WET PEFC
75 x 150mm & wider plus or minus 1-2mm Select & better WET PEFC

Appearance Red/brown appearance
Durability Moderately durable, reasonable resistance to decay but sapwood liable to beetle & termite attack.
Working properties Silica content causes rapid dulling of blades and high resinous levels affects saws during converstion.
Seasoning Kiln drying with care but still causes shrinkage & distortion
Uses Lorry bodies and industrial flooring.

Durability Very resistant to fungal decay and resistant to termites and marine borers.
Working Properties Extremely hard to work with hand tools and requires high powered machines to convert and plane. Requires pre-drilling before fixing.
