Block board has the advantages of good screw holding force, high strength, solid quality, sound absorption, heat insulation, etc., and the moisture content is not high, between 10% - 13%, so it is easy to process and widely used.

It is more stable than solid wood board, but it is afraid of dampness. It should be avoided to be used in kitchen and bathroom during construction.

The processing technology of joinery board can be divided into two types: machine splicing and hand splicing. Manual splicing is to insert the wood into the plywood manually. The extrusion pressure on the wood is small, the splicing is uneven, the gap is large, and the nail holding force is poor. It is not suitable for sawing and processing. It is only suitable for some sub projects of decoration, such as making cushion wool board of solid wood floor. However, the machine assembled plate is subject to large extrusion pressure, small gap, flat splicing, even bearing capacity, long-term use, compact structure and not easy to deform.
