OSB, short for Oriented Strand Board, is made with oriented strands. It's important to note the oriented strands. The surface flakes are arranged longitudinally, while the core flakes are arranged transversely. This three-layer structure, crisscrossed, restructures the wood's grain structure, completely eliminating the effects of internal stress on processing, making it exceptionally easy to work with and moisture-resistant.
I believe that with Zhoubao's tireless popularization, everyone has a general understanding of OSB boards. Then the question is, do you know that OSB boards actually belong to a large family?
How many types of OSB boards are there?
OSB has become one of the most promising wood-based panels due to its health and environmental benefits. This has also earned it a wide range of applications and development opportunities. my country, referring to the European EN300 standard, categorizes OSB into four grades. Let's take a look at the members of the OSB family!
01. OSB1
It is a general-purpose non-load-bearing board suitable for interior decoration materials and furniture in dry conditions;
02. OSB2
It is a load-bearing sheet material, suitable for dry conditions;
03. OSB3
It is a load-bearing board suitable for wet conditions;
04. OSB4
It is a load-bearing board suitable for wet conditions.
Different levels, applications in different fields
Which grade is suitable for the decoration industry?
OSB2 is mainly used in buildings and homes, and is an upgraded product of blockboard and multi-layer board.
Which grade is suitable for the furniture industry?
OSB2 has excellent processing properties due to its reconstructed wood structure, load-bearing and dimensional stability, and is suitable for furniture making.
Which grade is suitable for construction projects?
OSB3 is used for indoor and outdoor structural materials, decorative materials, concrete formwork, etc.
Which grade is suitable for flooring?
OSB3 is the base material of solid wood composite flooring, which replaces density board, blockboard and multi-layer board. It has the characteristics of moisture resistance, stable performance and no deformation.
Five advantages of OSB board
Environmental protection and safety
Strictly selected high-quality pine wood, using MDI glue, environmentally friendly and healthy.
Strong structure
The core shavings are laid in multiple layers in a directional manner to eliminate the internal stress of the board. There are no joints, gaps or cracks inside, and the overall structure is uniform. The middle plate is added to the upper and lower surfaces to further enhance the overall strength and support capacity.
impact resistant
It has excellent static bending strength, elastic modulus and impact resistance.
Not easy to deform
The density deviation within the board is small, the moisture absorption rate is low, and it is not easy to deform.
Good nail holding force, easy to process
The board surface and board edges have strong screw holding power, the furniture is durable, and the processing is convenient, meeting various requirements such as sawing, sanding, drilling, nailing, and filing.
As a new type of environmentally friendly building decoration material, OSB board is widely used in building structure, interior decoration and design, furniture manufacturing and other fields. It is the well-deserved "natural goddess" in the board industry.
