What Is an Oriented Strand Board?
Oriented strand board (OSB) is a panel-shaped building material made by processing wood into thin, long fiber-like strands, aligning them directionally, and then laminating and bonding them.
While similar to plywood, it is characterized by a more random fiber arrangement and manufacturing process. OSB demonstrates strength and durability through elements such as fiber directionality, adhesive, and laminated structure. By laminating fibers with directional alignment, it achieves high strength and rigidity, and using durable adhesives enhances the overall panel strength. Additionally, stacking multiple layers increases thickness and strength.
It finds applications in various sectors such as structural panels, interior materials, furniture, and packaging materials. Particularly as structural panels, it is widely used for structural components such as walls, floors, and roofs.
