OSB3 (Oriented Strand Board 3) is a strong and versatile engineered wood panel designed for load-bearing applications in humid conditions. Manufactured from compressed wood strands bonded with moisture-resistant adhesives, OSB3 offers excellent strength, durability, and dimensional stability. It is commonly used in roofing, flooring, wall sheathing, and general construction due to its cost-effectiveness and reliability. Its consistent structure and high load-bearing capacity make it a preferred choice for both residential and commercial building projects.
