Standing: big trees, the canopy can be up to 45 meters in diameter at breast height of 0.6 to 1 meter, with the root plate. Bark gray, from cracks, scaly off. Material: diffuse porous wood, while the proportion of the value of the original timber 0.80g / cm3, fresh material 1100-1200kg / m3, the original moisture content of wood when 12% 790kg / m3. Side, the obvious difference between heartwood, sapwood white heartwood brown, with shades of white ribbon wide stripes, very extraordinary. Inclined to slightly staggered wood processing, wood muscle slightly rough but uniform, with weak luster, even in the original timber with the resin bag. Kiln drying: Shrinkage great tangential 11.5%, 6.8% radial, easy warping and cracking, when the village should adopt the system path cut method, and slow down the speed of kiln dried, preferably in electronic dehumidification kiln drying this species, avoid the use of steam kiln. Workability: easy sawing, planing but because there is an inverse staggered wood processing and wood processing, it should be long low planing solution degrees to 15 ° ~ 20 °, get smooth planing flatness of optically active sand. Painting of the can, nail holding power is good. Purpose: Flat-up of the cut plywood veneer, wood floors, and toughness of this species is quite large, can be used for tool handles and skis.
