Explanation:
Detailed explanation-1: -Oriented strand board (OSB) is an engineered, composite, wood-based panel product, designed as a structural replacement for sheathing grades of plywood. OSB is characterised by its constituent strand elements which vary in size and aspect ratio and are larger than the chips from which chipboard is pressed.
Detailed explanation-2: -To manufacture OSB, debarked logs are sliced into long, thin wood elements called strands. The strands are dried, blended with resin and wax, and formed into thick, loosely consolidated mats that are pressed under heat and pressure into large panels.
