Oriented strand board is also called which material?

• A. Plywood
• B. O.S.B.
• C. MDO
• D. Hardboard

Answer: (B)

Oriented strand board is a type of engineered wood panel formed from wood strands laid in cross-oriented layers and bonded with adhesive. The material is commonly referred to by its initials, OSB. This distinguishes it from plywood, which uses veneer sheets; MDO, which is plywood with a smooth overlay; and hardboard, which is a dense fiberboard. OSB’s construction—strands oriented in multiple directions—gives good stiffness and strength for sheathing and subflooring, usually at a lower cost.
