Structural OSB Board (Oriented Strand Board) is a high-performance engineered wood panel designed for load-bearing construction applications.
Manufactured by compressing cross-oriented wood strands with moisture-resistant resin under high temperature and pressure, structural OSB offers excellent strength, dimensional stability and consistent structural performance.
Compared with traditional plywood, structural OSB board provides a cost-effective and reliable solution for roofing, flooring, wall sheathing and timber frame construction.
LUJU structural OSB board is available in OSB 3 and OSB 4 grades to meet different moisture resistance and structural load requirements.
Key Features
- High Load-bearing Strength：Designed for structural construction applications.
- Excellent Dimensional Stability：Resists warping, cracking and deformation.
- Moisture-resistant Performance：OSB 3 and OSB 4 available for humid conditions.
- Uniform Internal Structure：No core voids, consistent strength performance.
- Easy Installation：Suitable for cutting, fastening and structural assembly.
- Cost-effective Structural Panel：Alternative to plywood in many construction projects.
