Chinese wholesale Concrete Wall Formwork Systems - Oriented Strand Board (OSB) – Sampmax

Oriented Strand Board (OSB) is a multifunctional structural plank. It is a kind of directional structure board made of small-diameter timber, thinned timber, and wood core through special equipment and processed into shavings through various processes.
The surface layer of OSB is arranged longitudinally, and the core layer is arranged horizontally. This crisscross reorganization of the wood texture structure makes OSB easy to process and moisture resistant. Because the OSB has a directional structure inside, no joints, no gaps, or cracks, the overall uniformity is good, and the internal bonding strength is extremely high, so both the center and the edges have super nail-holding ability.

Compared with plywood, medium-density fiberboard and blockboard, “OSB” has a small linear expansion coefficient, good stability, uniform material, and higher screw-holding power;
Because the shavings are arranged in a certain direction, its longitudinal bending strength is much greater than that of the transverse direction, so it can be used as a structural material and as a force-bearing member.
In addition, it can be processed like wood by sawing, sanding, planing, drilling, nailing, filing, etc. It is a good material for building structure, interior decoration and furniture manufacturing.

OSB’s advantage of formaldehyde-free release is regarded as the most promising wood-based panel in the future, and “OSB” has a broad space for use and development. The market’s fancy is the advantage of no formaldehyde release, which can be mainly used for: floors, walls and roofs, I-beams, structural isolation panels, packaging boxes, cargo pallets and storage boxes, commodity shelves, industrial desktops, Hardwood floor cores, air baffles and guardrails, decorative wall panels, precast concrete molding, container floors, bowling alleys, etc.
