What is the material of OSB board? What are the benefits? OSB board is a kind of directional structure board, which is made from small diameter wood, thinning wood and wood core, and processed by special equipment with long planing pieces (generally 40-100 mm long, 5-20 mm wide and 0.3-0.7 mm thick), through deoiling, drying, sizing, directional paving, hot pressing and other processes.
The surface plane of OSB board is arranged longitudinally, and the core plane is arranged transversely. This kind of crisscross arrangement, directional structural board, recombined woodiness grain structure, eliminated the influence of wood internal stress to processing completely, make it have extraordinary easy processing sex and moistureproof sex. Because OSB has a directional structure, no joint, no gap, no crack, good overall uniformity, and high internal bonding strength, it has a super nail holding ability that ordinary plate can't compare with no matter in the center or at the edge.
