Oriented Strand Board

Oriented Strand Board is suitable for general applications in indoor and outdoor conditions, providing unlimited possibilities for your development of construction projects. Oriented strand board and plywood are composed of strands arranged in layers at right angles, and are usually regarded as equal in performance.

Product Details

What is oriented strand board?

Oriented strand board, also known as OSB, is a type of engineered wood similar to particle board,formed by adding adhesives and then compressing layers of wood strands(flakes) in specific orientations. OSB may have a rough and variegated surface with the individual strips of around 2.5*15cm(1.0 by 5.9 inches), lying unevenly across each other,and is produced in a variety of types and thicknesses.

The high performance OSB from Treezo Group is made of 100% formaldehyde-free resin adhesive and selected wood. The result is ultra-low emissions (<0.03 ppm) at the level of natural wood. It is the best choice for environmentally sensitive applications where emissions are of concern.

What are the features of OSB for Australia?

1. High environmental performance: The authentic osb board is produced according to the high-level environmental protection standards. It is safe to use with ISO9001:2000, FSC, CARB Certification. The glue used in the osb board is extracted from formaldehyde-free resin.

2. Good stability: The osb board is dried and deoiled at high temperature, has great strength and hardness, which is not easy to deform and crack. The interior of the osb is a directional structure, without joints, gaps and cracks, with good overall uniformity and excellent internal bonding strength.

3. Personalization: The osb board has many materials of colors and styles, which can meet the personalized needs of consumers.Click here to custom your special osb products!

4. Good moisture-proof and anti-corrosion performance: The surface shavings are arranged vertically, and the core shavings are arranged horizontally. This criss-cross arrangement reorganizes the wood texture structure and completely eliminates the influence of the internal stress of the wood on processing, making it exceptionally easy to process and moisture-proof in Australia.

5. Super nail gripping power: The osb board has super nail gripping power unmatched by ordinary boards regardless of the center or the edge.

6. Easy for installation: Relative to its strength, Oriented Strand Board panels are lightweight and easy to handle and install.

What is oriented strand board used for?

The combination of Oriented Strand Board wood and adhesive creates a strong, dimensionally stable panel that can resist deflection, delamination and warping; similarly, the panel can resist tilt and shape deformation when encountering harsh wind and seismic conditions. Ideal for:

1. Overall wardrobes, cabinets, TV cabinets, shoe cabinets, bathroom cabinets, wine cabinets.

2. Office furniture, packaging materials, container bottom plates.

3. Wooden house construction, villa construction, indoor furniture, building templates etc.

Oriented Strand Board

Is oriented strand board stronger than plywood?

In today's architectural world, almost all structures are built with panels, at least part of the infrastructure. Builders have two widely available plywood or particleboard options, each with advantages and disadvantages during their usage.

Oriented Strand Board

OSB is a rigid panel made by grinding logs into thin strands that look a bit like wood chips. The strands are arranged in a cross-hatched direction and mixed with the material to bond them together, then finished in a heat press. Finished particleboard has a consistent density throughout the panel and can be made into boards up to 16 feet long or more. Historically, the main advantage of particleboard has come from its cheaper manufacturing cost. For most uses, such as subfloors and siding, it is rated equivalent to plywood. However, its performance in humid climates can be problematic as it tends to retain moisture, which can cause board edges to swell.


Plywood is a sturdy panel made by layering thin veneers from logs. Veneers are laminated together vertically to form solid panels, usually manufactured in 8 or 10 foot lengths. The main advantage of plywood is its moisture resistance. Many flooring contractors refuse to use anything else as a subfloor because it is considered more consistent and reliable. Plywood is generally more expensive than OSB, which is a major disadvantage.

Overall, the two types of structural panels are rated as very similar by agencies that specialize in building codes and material quality. Plywood can be considered higher quality, but many believe the truth comes from its long history, more consistent appearance, and higher cost. OSB is very commonly used for wall sheathing as well as roofs and floors.
