OSB is manufactured from waterproof heat-cured adhesives and rectangular shaped wood strands that are arranged in cross-oriented layers, similar to plywood. The result is a structural engineered structural use wood panel that shares many of the strength and performance characteristics of plywood. Produced in huge, continuous mats, OSB is a solid panel product of consistent quality with no laps, gaps or voids.

OSB is widely used in residential and commercial construction, and is gaining popularity in markets such as materials handling and the manufacturing of upholstered furniture. The manufacturing process makes it possible for panel makers to add innovative features such as a slip-resistant texture to panels designed for roof sheathing, and to supply oversized and metric panels.
