OSB (Oriented Strand Board) is an engineered wood panel made by compressing layers of
wood strands (thin,
rectangular flakes) that are oriented in specific directions and bonded together with strong
waterproof resins
under high heat and pressure. The strands are typically arranged in cross-oriented layers to
enhance strength
and structural stability.

OSB is widely used in construction applications such as wall sheathing, roof decking,
flooring, packaging, and
structural panels. It is known for its high strength-to-weight ratio, good load-bearing
capacity, and cost-
effectiveness compared to plywood.

OSB is valued for its uniformity, durability, and efficient use of wood resources. It performs
well in structural
applications, especially when properly sealed or protected from moisture, making it a
popular material in modern
building systems and prefabricated construction.
