What is OSB/1?

Definition and Composition

OSB/1 is a type of Oriented Strand Board, which is an engineered wood product made by compressing layers of wood strands in specific orientations. These strands are bonded together using adhesives and wax, resulting in a sturdy and durable board.

Manufacturing Process

  1. Strand Preparation: Wood strands are sliced from logs and dried to the appropriate moisture content.
  2. Blending: Strands are mixed with adhesives and wax to enhance bonding and moisture resistance.
  3. Mat Formation: The blended strands are layered in specific orientations to create a mat.
  4. Pressing: The mat is subjected to high pressure and temperature to form a solid board.
  5. Cutting and Finishing: The board is cut to size and finished as per requirements.
