Fire Retardant OSB Panel Moisture Resistant Timber Oriented Strand Board

Product Description

Product Description

Oriented strand board (OSB)

OSB (Oriented Strand Board) is an engineered wood panel made by layering strands of wood in specific orientations and bonding them with a waterproof resin under heat and pressure. It's strong, dimensionally stable, and commonly used in residential and commercial construction.

Four types of OSB

OSB comes in various grades and thicknesses, depending on its intended use. The most common types are:

OSB/1: Suitable for general use in dry conditions.

OSB/2: Load-bearing boards for dry conditions.
OSB/3: Load-bearing boards that can be used in humid environments.
OSB/4: Heavy-duty load-bearing boards for humid conditions.

The thickness of OSB panels can range from 6mm to 25mm or more, with thicker boards being used for heavier construction applications such as flooring and roofing.

Features of Our OSB

1. The OSB has good overall uniformity, and it will not expand or shrink significantly when it is heated or cooled. Therefore, the internal structure has very high stability, and it has super nail holding ability both in the center and at the edge.
2. The OSB is very stable, generally free from deformation and cracking, and has a long service life under normal conditions.
3. Because of the advantages of OSB, such as no joint, no gap, and no crack, it has a good waterproof and moisture-proof ability with adhesive.

How is Our OSB Made?

The process of creating OSB involves layering wood strands that are typically 3 to 4 inches long. These strands are mixed with a waterproof resin and then oriented in layers to create a panel that has uniform strength across all directions. The layers are pressed under high pressure and heat to form a solid, durable board.

Common Uses of OSB

OSB is primarily used in construction, especially in the following areas: Walls and Roof Sheathing, Flooring, Furniture, Packaging
