Oriented Strand Board Factory - Dongstar® - China OSB Board Manufacturer

OSB (Oriented Strand Board) is a popular wood-based panel known for its versatility and strength. As an OSB board manufacturer from China, we take pride in using high-quality raw materials and excellent adhesive options to meet the diverse needs of our customers.

OSB Types

Our OSB boards are made from carefully selected raw materials including common woods such as poplar, pine, eucalyptus and other compatible species. The wood comes from responsibly managed forests, ensuring a sustainable supply chain. Logs are processed into long, thin strands or sheets that form the basic building blocks of OSB.

OSB Grades

OSB 1, OSB 2, and OSB 3 are different grades of Oriented Strand Board (OSB), a type of engineered wood panel made from strands of wood arranged in layers and bonded together with adhesives. Each grade has specific characteristics and applications:

OSB 1:

Description: OSB 1 is a basic-grade oriented strand board designed for interior use in dry conditions.

Applications: It is commonly used for packaging, pallets, and other non-structural applications where moisture exposure is limited.

OSB 2:

Description: OSB 2 is a general-purpose oriented strand board suitable for use in dry conditions.

Applications: It is commonly used for furniture, DIY projects, and general construction applications where moderate load-bearing capacity is required.

OSB 3:

Description: OSB 3 is a structural-grade oriented strand board engineered for use in humid conditions and load-bearing applications.

Applications: It is widely used in construction for flooring, roof decking, wall sheathing, and structural components due to its enhanced strength, moisture resistance, and dimensional stability.

OSB 1 vs OSB 2 vs OSB 3

  • OSB 1 is the least durable and has limited load-bearing capabilities, suitable for non-structural applications with minimal moisture exposure.
  • OSB 2 offers better strength and can handle moderate loads, making it suitable for general-purpose use in dry conditions.
  • OSB 3 is the highest-grade panel, designed for structural applications and exposure to higher levels of humidity.

OSB Glue

We offer a variety of glue options to suit different requirements and applications:
  • MR (Moisture Resistant): MR glue, also known as interior glue, is a cost-effective option for interior applications where limited exposure to moisture is expected.
  • E2, E1, E0: These are the formaldehyde emission classes of the glues used in OSB manufacture. The emission level of E2 is higher, and the emission level of E1 and E0 is lower, meeting more stringent environmental and health standards.
  • ENF (Environmentally Friendly): ENF glue is designed to have minimal impact on the environment. It complies with strict environmental regulations and is suitable for projects where sustainability is a priority.
  • PMDI (polymerized diphenylmethane diisocyanate): PMDI glue has excellent bond strength and moisture resistance. It ensures the durability and stability of the OSB board, making it suitable for demanding applications.
  • WBP (Water Boiling) / Phenolic Glue: WBP and phenolic glue provide excellent water resistance, making OSB boards suitable for outdoor and moisture-exposed applications. They feature enhanced durability and dimensional stability.
  • Melamine: Melamine glue is known for its moisture resistance and excellent surface finish. It provides additional moisture protection and can be used in applications where moisture resistance is required.

OSB Application

Our OSB boards are suitable for a variety of industries and projects including:

  • Construction: OSB panels are widely used in the construction of roofs, wall panels, subfloors and structural components. They provide stability, strength and cost-effectiveness.
  • Furniture and cabinets: OSB boards are used in the manufacture of furniture, including cabinets, shelves and tables, offering modern and versatile solutions.
  • Packaging: OSB boards are used in packaging materials such as crates, pallets and containers for their strength and durability.
  • DIY & CRAFTS: OSB boards are popular with DIYers and crafters for creating unique projects, shelves, and decorative items.
