Plywood is a wood segment spin into a single board or cut by the wood side cut into thin wood, and then with adhesive glue made of three or multi-layer edgy sheet material, usually with odd layers of single board, and the fiber direction of adjacent layers of single board each vertical plycerate, plywood will improve the utilization rate of wood, which is also the reason why plywood is very popular.

By the wooden segment spin cut into a single board or by the wood cut into thin wood is called plywood, and then with adhesive glue made of three or more layers of plate-like material, generally with odd layers of single board, but also to make adjacent layers of single board fiber direction and vertical glue. One of the materials often used to make furniture is a kind of artificial board.

A set of single boards is generally made of sheets made of vertical sheeting in the direction of the adjacent layers, usually the table plate and the inner plate are symmetrically configured on the center layer or on both sides of the core. After the coating of the single board in the direction of the wood pattern crisscrossed into the slab, in the heating or non-heating conditions to suppress it. The number of layers is usually odd, and there are even numbers but are relatively small. Three-in-one board, five-in-one board and so on are often used in daily life. Plywood manufacturers can improve the utilization rate of wood, is a major way to save wood.
