Plywood

Plywood is a three-layer or multi-layer plate-like material made of wood segments cut into veneer or thin wood cut by wood square planing, and then glued with adhesive. Usually, odd layers of veneer are used, and the fiber directions of adjacent layers of veneer are vertically glued to each other.

wood-based panels, and can also be used for aircraft, ships, trains, automobiles, buildings and packaging boxes. A group of veneers is usually formed by gluing each other vertically according to the direction of adjacent layers of wood grain, and usually the surface plate and the inner plate are evenly arranged on both sides of the central layer or the core of the board. A slab made of gelled veneers crisscrossed in the direction of wood grain and pressed under heated or unheated conditions. The number of layers is usually odd, and a few have even numbers. The difference of physical and mechanical properties in vertical and horizontal directions is small. Commonly used types of plywood are plywood, plywood and so on. Plywood can improve the utilization rate of wood and is a main way to save wood.

The usual length and width specifications are :1220×2440mm, and the thickness specifications are generally :3, 5, 9, 12, 15, 18mm and so on.
