KAPUR (Dryobalanops spp.) 
General Description : Sapwood is well defined and pale coloured. The heartwood is red-brown when freshly cut, weathering to a light red-brown. It has no lustre or figure. Ripple marks are often distinct. The grain is slightly interlocked or spiral and texture is coarse and even. Resin canals usually without contents occur characteristically in concentric lines on the end surface but the wood is not resinous. It often has a camphor-like odour.   

Principal Uses
: House posts, beams, posts, joists, door and window frames, flooring, stair treads and stringers, keels, keelson ribs and framework of boats, carriages and wagon frames, lorry and truck frames, floor boards, etc. However, in domestic flooring and internal fittings where finished appearance is important, care should be taken in fixing because of a tendency to develop an unsightly black stain in contact with iron nails, screws or other fittings.

Veneering : The timber is considered as potentially acceptable for plywood manufacture.

KERUING (Dipterocarpus spp.)     
General Description : Sapwood is well defined and grey-brown in colour. The heartwood is red-brown or purple-red, weathering to a dark red-brown. Surface dull and often tacky. Grain almost straight: texture moderately coarse and even. It has a faint resinous odour. Resin exudation may occur in inadequately seasoned wood of some species.   

Principal Uses : Heavy construction, posts, beams, joists, rafters, staircase stringers, wharf and bridge decking, keels and framework of boats, framework of carriages and wagons, wagon flooring, truck body work, fence posts, flooring etc. It is one of the preferred timbers in England for gymnasium equipment. Treated with preservatives preferably with creosote, it is an excellent wood for salt water piling, harbour works, bridges, railway sleepers, telegraph poles and power-line poles. Abundant supply is one of the best features of this wood.

Veneering : A trial on D. cornutus shows that is potentially acceptable for plywood manufacture.

Principal Uses
: Treated with preservatives, Kempas is suitable for all heavy construction, railway sleepers, telegraph and power line poles, fence posts, etc. The untreated timber is suitable for all structures under cover where termites are not a hazard, including posts, beams, joists, rafters, etc. It is a very attractive timber for parquet flooring but some manufacturers consider it too hard to machine. It makes good walking sticks and is a favourite wood for charcoal manufacture.

Veneering : Not generally suitable because of its hardness and conversion difficulties unless preheating is employed.
