This canopy tree is usually found in colline or montane forest up to 1850m, sometimes in depleted Agathis forest, rarely occurring in swamp forest. Heartwood Color White Brown Red Yellow Purple Pink Orange Tan Reddish brown Pale red to pink Sapwood Color Red Brown Yellow White Pale brown Orangish Clearly differentiated from the heartwood Grain Figure Interlocked Zig Zag Ribbon (figure) Ribbon figure Interlocked Figure is sometimes in a zig zag pattern Quartersawn stock has a ribbon figure and flatsawn surfaces sometimes have a zig zag pattern. Texture Fine Medium Uneven textured Medium coarse to coarse Luster Medium Low Lustrous Natural Growth Defects Mostly knot free Over mature trees may have some white pocket rot Natural Durability Non-durable Perishable Susceptible to insect attack Susceptible to pin-hole borer, termite and marine borer attack May stain under damp conditions Durable above ground Odor Has an odor No specific smell or taste Kiln Schedules T2 - D4 (4/4); T2 - D3 (8/4) US Schedule A (4/4) United Kingdom Drying Defects Checking Distortion Moderate twist/warp Ease of Drying Fairly Easy Rapidly Slowly Reconditioning Treatement Little degrade Thinner boards (<1") dry easily Special attention required Good kiln-drying properties Stack wood properly. A 4 to 5 hour steaming treatment, with stacks weighted down, can reduce twist and stresses Kiln Drying Rate Naturally dries quickly Naturally dries slowly Tree Size Tree height is 10-20 m Tree height is 20-30 m Bole length is 10-20 m Stems are straight and cylindrical, and are usually clear of branches to 40 to 60 feet (12 to 18 m). The species is described as fast-growing. Blunting Effect Little Medium effect Interlocked grain has a medium blunting effect on cutting edges Boring Fairly easy to very easy Fair to good results Easy Carving Fair to Good Results Fairly Easy to Very Easy Cutting Resistance Easy to saw Material with interlocked grain can be difficult. Cutting Resistance with green wood is easy Gluing Fairly Easy to Very Easy Glues well Mortising Fair to Good Results Fairly Easy to Very Easy Fairly Difficult to Very Difficult Moulding Fairly Easy to Very Easy Fair to Good Results Fairly Difficult to Very Difficult Movement in Service Stable Nailing Fair to Good Results Very Good to Excellent Results Holds nails well Easy to nail Planing Fair to Good Results Fairly Easy to Very Easy Fairly Difficult to Very Difficult Special attention required Good planing properties Interlocked grain may tear. Recommended that a reduced cutting angle is used Resistance to Impregnation Permeable heartwood Permeable sapwood Heartwood is extremely resistant Response to Hand Tools Easy to Work Responds Readily Fairly Difficult to Difficult to Work Good response Routing & Recessing Fair to Good Results Fairly Easy to Very Easy Sanding Poor sanding qualities Cross grain can make sanding qualities poor Screwing Fair to Good Results Very Good to Excellent Results Fairly Easy to Very Easy Good screw holding properties Turning Fair to Good Results Fairly Easy to Very Easy Turned surfaces tend to be woolly Polishing Very Good to Excellent Results Fair to Good Results Smooth polished surface Requires a filler Staining Very Good to Excellent Results Fair to Good Results Varnishing Good results Strength Properties Compression strength (parallel to grain) = high The bending strength of air-dried wood of the species is similar to that of Teak, which is considered to be strong. Strength in compression parallel to grain is in the high range. Other species in this range include Teak, White oak, and Hard maple. It is a heavy wood. The density is high.
