When it comes to plywood, if you're not a professional, you probably don't have a very good understanding of it. In fact, plywood is often used in our home decoration, usually in customized furniture, and is the main material used in furniture. It is also a building material used for decoration, which will be installed and used in the early stages of construction. Although this type of board is widely used, there are also many consumers who are confused by its different specifications. So, let's take a look together at what plywood is? What are the specifications of plywood?
What is plywood? How much do you know about plywood specifications?
1、 What is plywood?
In fact, plywood is a new type of artificial board, which is composed of surface board and inner layer board. It is generally symmetrically arranged on both sides of the center layer or board core, and then bonded with wood adhesive to form a whole. This can help us save wood resources, so it is also a very fashionable and environmentally friendly reasonable utilization. Generally, plywood has three or more layers, with odd numbered layers being the majority. After modern precision processing, the physical and mechanical properties of the board are greatly improved. The increase in specifications of plywood has also made it more suitable for furniture manufacturing and construction, gradually occupying a dominant position in other industries such as shipbuilding and aircraft.
2、 What are the specifications of plywood?
The length and width of plywood may vary slightly due to different manufacturers, but generally there may be 1220 × 2440mm, 1220 × 1830mm, 915 × 1830mm, 915 × The specifications of 2135mm can be used according to our needs, or different lengths and widths of plywood can be selected for use. The thickness of plywood is actually determined by the number of layers. In addition to the surface board, the more layers the inner layer board is equipped with, the thicker its thickness will be. However, if plywood is classified solely based on thickness, it can be divided into several specifications such as 3, 5, 9, 12, 15, and 18 millimeters. So there is no fixed length and width specification for plywood.

3、 What are the categories of plywood?
1. A type of plywood
This type of plywood has a very long lifespan and is resistant to climate and boiling water. It is generally suitable for use in ships, so its price is also very expensive.
2. Class II plywood
This type of plywood can be immersed in cold water and immersed in hot water for a short period of time. It is also a type of water-resistant plywood, and its performance is relatively poor compared to other types of plywood.
3. Three types of plywood
This type of plywood is generally more moisture resistant, but cannot be soaked in water, making it more suitable for furniture and general construction.
4. Four types of plywood
This type of plywood is relatively inexpensive because it is not moisture-proof or water-resistant, and can be used without special requirements.
What are the categories of plywood?
The above is the relevant knowledge about what plywood is and the specifications that the editor has compiled for everyone. In summary, plywood is a piece of board that is glued together by several boards, which helps us save resources. However, its specifications are not fixed because its width and thickness are not fixed values.
