OSB (Oriented Strand Board) is an engineered wood panel made of wood strands, which are in cross-oriented pattern and bonded with adhesives under heat and pressure.

OSB is different from MDF and Particle Board. MDF is made of wood powder. Particle Board is made of wood powder and very small wood chips which are put in random pattern. These are why OSB is better than MDF and Particle Board in strength, stiffness and consistency.

Depending on the glue used, OSB can be suitable for interior or exterior applications and be classified into 4 groups (BS EN 300):

1, OSB/1, General purpose panels for use in dry conditions
2, OSB/2, Load-bearing panels for use in dry conditions
3, OSB/3, Load-bearing panels for use in humid conditions
4, OSB/4, Heavy duty load-bearing panels for use in humid conditions

OSB is cheaper than plywood. The wood strands for OSB come from cheaper small logs. The wood veneers for plywood come from large logs.

OSB is a good substitute for plywood in some applications, such as furniture, roof, wall, sub floor, DIY and so on. The growth in global OSB consumption has been rapid in recent years.

China not only produces/exports OSB, but also imports OSB.
