what is plywood?

In fact, plywood is a new type of wood-based board, which is composed of the table board and the inner board, and is generally symmetrically configured on both sides of the central layer or the board core, and then the wood adhesive is used to bond these plate-like materials into a whole, which can help us save wood resources, so it is also a very fashionable and very environmentally friendly rational use. Generally, plywood will have more than three layers, and the odd layer will be more, and the physical and mechanical properties of the board will be greatly improved after modern fine processing. The increase in plywood specifications also makes it more suitable for furniture manufacturing and construction, and it has gradually occupied a dominant position in other industries, such as shipbuilding and aircraft.

what are the specifications of plywood?

The length and width of plywood will vary slightly because the manufacturer is different, but generally there will be 1220×2440mm, 1220×1830mm, 915×1830mm, 915×2135mm of these specifications, according to our needs to use, you can also choose different length and width plywood to use. The thickness of the plywood is actually determined by the number of layers, in addition to the table board, the more layers of the inner board configuration, the thicker its thickness will be, but only from the thickness to the plywood classification, can be divided into 3, 5, 9, 12, 15 and 18 mm of these categories of specifications. Therefore, there is no fixed length and width specification for plywood.
