The thickness of each layer are from 1.5mm to 5.5mm. The center two layers of veneer have the same grain and thickness and are manufactured by similar species. The grain of adjacent veneer are perpendicular while the grain direction of wood panel are parallel with the length direction. The thickness of the plywood is 2 to 30mm and the common dimension is 2440mm×1220mm. ;工程木-胶合木生产过程工程木-胶合木生产过程Engineered lumber – plywood manufacturing process ;工程木简介-定向刨花板Engineered Lumber – Orientated strand board;工程木简介-OSB板类型Engineered Lumber – OSB types;工程木简介-定向刨花板加工流程Engineered Lumber – Orientated strand board manufacturing process;用于建筑施工中的OSB板应该是定级为结构外用的材料。OSB的出厂国和厂家不同，在OSB板上的盖章也有区别。 OSB used in construction should be rate
