One of the new varieties of oriented strand board. When laying and shaping the shavings, the upper and lower surface layers of the oriented strand board are arranged longitudinally with mixed adhesive shavings according to their fiber direction, while the core layer shavings are arranged transversely to form a three-layer structural board embryo, which is then hot pressed into oriented strand board. The shape of this particle board requires a large aspect ratio, and the thickness is slightly thicker than that of ordinary particle boards. The methods of directional paving include mechanical orientation and electrostatic orientation. The former is suitable for directional paving of large shavings, while the latter is suitable for directional paving of small shavings. The directional paving of oriented strand board gives it the characteristic of high strength in a certain direction, and it is often used as a structural material instead of plywood

Ousong board has been widely used in the fields of construction, decoration, furniture, packaging, etc. in developed countries such as North America, Europe, and Japan.

The usual length and width specifications are 1220 × 2440mm, while thickness specifications generally include 3, 5, 9, 12, 15, 18mm, etc. The main tree species include: beech, camphor, willow, poplar, eucalyptus, etc.
