What Is Plywood

Plywood is a three-layer or multi-layer plate-like material made of wood segments that are rotary cut into veneer or cut into thin wood by wood planer, and then glued together with adhesive, usually with odd layers of veneer, and the fiber direction of adjacent layers of veneer is glued perpendicular to each other.

Plywood is one of the commonly used materials for furniture, one of the three major wood-based panels, and can also be used for aircraft, ships, trains, automobiles, construction and packaging boxes. A group of veneers is usually glued perpendicular to each other in the direction of the wood grain of adjacent layers, and the surface and inner layers are usually symmetrically arranged on both sides of the central layer or core. It is made of a slab made of glued veneer criss-crossed in the direction of the wood grain, pressed under heated or unheated conditions. The number of layers is generally odd, and a few have even numbers. There is little difference in physical and mechanical properties in the vertical and horizontal directions. Commonly used types of plywood are plywood, plywood, etc. Plywood can improve the utilization rate of wood and is a major way to save wood.
