Oriented Strand Board (OSB) is an engineered wood panel made from compressed wood strands bonded with strong adhesives under heat and pressure. It offers high strength, good dimensional stability, and a uniform structure with a rough-sanded surface.
OSB is durable, cost-effective, and easy to process, making it widely used in flooring, wall sheathing, roofing, furniture, and packaging. It is available in different sizes, thicknesses, and grades to meet various construction and performance needs.
With strong load-bearing capacity and impact resistance, OSB performs reliably in both residential and commercial applications across different climates.
OSB (Oriented Strand Board), also known as oriented strand particle board, is an engineered wood panel made by arranging thin wood strands in specific orientations.
These strands are combined with eco-friendly adhesives and hot-pressed under high temperature and pressure.
Due to its unique cross-oriented structure, OSB offers excellent structural strength, moisture resistance (in higher grades), strong nail-holding ability, and dimensional stability.
It is widely used in building construction, including wall sheathing, roofing, and subflooring in wood-frame houses. OSB is also used in furniture manufacturing and interior decoration.

Learn more about the pros and cons of our products.
| Advantages | Disadvantages |
|---|---|
| High strength and excellent load-bearing capacity | Rough surface, requires finishing for decorative use |
| Good moisture resistance (especially higher-grade OSB) | Edges are prone to moisture absorption and require proper sealing |
| Cost-effective compared with plywood | May produce splinters during cutting or processing |
| Environmentally controllable with low-formaldehyde adhesives | Low-quality products may still emit formaldehyde |
