What is OSB ?
OSB is Oriented strand board, is the upgrading of the traditional particleboard products,
its mechanical properties with directionality, durability, moisture resistance and dimensional stability than ordinary particleboard.
With a small expansion coefficient, no distortion, good stability, uniform material and nail holding high performance.
Oriented strand board (OSB), also known as flakeboard, sterling board and aspenite in British English,
is a type of engineered wood similar to particle board, formed by adding adhesives and then compressing
layers of wood strands (flakes) in specific orientations. It was invented by Armin Elmendorf in California in 1963.
