High bending strength little linear expansion coefficient Strong nail-holding strong shock resistance Moisture-proof and easily work Tight construction and high strength No ratten or decay Low formaldehyde emission Good heat and sound resistant. easy to be coated.     Oriented Strand Board, abbreviated as OSB, is made based on applying fast-growing trees and trees hewed by interval such as pine and poplar as raw material, and processed after operations like wood slice-cutting, drying, sieving and selection , gluing, directionally loading and stowing , hot press shaping and others , which are realized by special equipment. OSB is structured in three layers, the top layer and bottom one are in longitudinal arrangement, the middle core layer is transversely arranged, such crisscross structure makes it a feature of high intensity. Being Characteristic mentioned above, OSB has a broader application in house-building, decoration and fitting, furniture article, floor and packing material.
