Both blockboard and plywood are plates that can be used for decoration, but there are also many differences between the two. Plywood manufacturers will make a simple distinction for you.
The raw material for the blockboard production is wood slats. The splicing of the wood slats results in a blockboard. The two surfaces of the blockboard are glued wood veneers, which are solid sheets. The veneer is the surface plate, and the surface below the core plate is the middle plate. In principle, the quality of the surface plate is allowed to vary. It can be sanded on one side, sanded on both sides, or not sanded on both sides. The core board of the blockboard must be the same species or tree species with similar performance, and the moisture content reaches 6-12%. Large voids and cracks are not allowed.
Plywood manufacturers produce plywood with a variety of classification criteria, including structure, surface processing, adhesive properties, processing methods, shapes, and applications. Plywood veneers are mostly full-width ones, and splicing is also allowed. The veneers on the symmetric layers on both sides of the center layer need to be of the same thickness, the same tree species, or close to the same performance. It is also necessary to ensure that the processing methods are the same and the texture direction is the same. There are four types of ordinary plywood, weather-resistant plywood, water-resistant plywood, moisture-resistant plywood, and non-moisture-resistant plywood.
