The difference between joinery board and plywood, the two kinds of boards should be distinguished

When interior decoration, some boards are often used, such as wood board and plywood. When many consumers buy these materials, it is often difficult to distinguish them. The following is a brief introduction the difference between joinery board and plywood, to help you purchase boards more conveniently.

1. Different production methods

The joinery board is actually the so-called big core board. It is a basic material commonly used in furniture production and decoration modeling. Its production method is mainly by splicing two pieces of veneer together by glue pressing. The wood strips of the specifications are spliced together using a jigsaw machine.

The production method of plywood is to turn wood segments into veneers, or to slice wood into thin wood, and then use special adhesives to glue the boards. Generally, there are three or more layers.

2. The scope of use is different

The difference between joinery board and plywood is also reflected in the different scope of use. Wood board is often used in the production of furniture products, and can also be used as indoor false walls, partition materials, and sometimes into doors and windows or the curtain box and so on. In addition to being a common material for furniture, plywood can also be used as a material for aircraft, ships, automobiles, buildings, and packaging boxes. However, the consistency of the material in the core is poor, and the possibility of deformation is very large, so it is not suitable for use as a cabinet door material.

3. The different specifications

At present, the size of common joinery board on the market is generally 1220mm × 2440mm. The thickness of such wood panels is 12mm, 15mm, 18mm, 20mm, but the more common ones are 15mm and 18mm. The thickness of plywood is generally 3mm, 5mm, 9mm, 12mm, 15mm and 18mm.

4. The internal structure is different

There is another difference between joinery board and plywood, that is their internal structures are different. The solid wood strips inside the joinery board are longitudinally spliced, but the plywood is formed according to the direction of the wood grain of the adjacent layers perpendicular to each other. The internal structure is different. The longitudinal splicing method of wood board will cause lateral deformation of the board due to the poor vertical bending strength.
