Plywood HUAI'AN SPRING WOOD INDUSTRY

Plywood is made by bonding an odd number of veneers with the grain of adjacent layers at right angles. Strength is balanced in both directions and the panel resists distortion. The Japanese standard size is 910 × 1,820 mm with 12, 15, 18 and 24 mm thicknesses. HARU PLYWOOD produces it in our own factory in Jiangsu, which has supplied Japanese customers on an OEM basis since it was established ten years ago, under the same quality control as our JAS-certified LVL. In construction plywood provides the surfaces: 12 mm floor sheathing, 9–12 mm wall sheathing — the designated facing of Japanese shear walls, where seismic performance depends directly on nail withdrawal — and 12 mm roof sheathing. Formwork plywood (konpane) is reused five to eight times. The floor, walls and roof of a timber house are all plywood surfaces. In furniture it is the most versatile substrate: shelves, backs and drawer bottoms; dining and desk tops; moulded plywood chair seats and backs; bed frames and cabinet sides. At equal thickness it is lighter than solid timber and wide door panels stay flat.
