However, wood is an anisotropic material with relatively low compressive, tensile and flexural strength. The dimensions of the wood elements are generally relatively large in order to achieve a predetermined load carrying capacity.
OSB board is a synthetic wood. The source of OSB, the term "European pine board", is oriented strand board (Oriented Strand Board, OSB), a novel board species that has developed internationally from Europe, seventies. The application of the European pine board on furniture has been unprecedented, and many large-scale furniture enterprises begin to use OSB to manufacture furniture, and the reason why the European pine board is liked by consumers is that formaldehyde is not released, and the European pine board is firm and durable, and the furniture is lighter in weight and better in flatness than furniture manufactured by medium-density fiber boards.
