First of all, the production of pallets can be a reasonable use of logs, because it is no sawdust, is the production of medium density fiberboard and particleboard good raw materials. Secondly, the weight of the plywood is high, the strength is high, and the texture is beautiful, which can make up some shortcomings of naturally occurring natural wood, such as knots, small size, deformation and vertical and horizontal mechanical difference. Again, the plywood also has the advantages of small deformation, large format, convenient construction, no warping, tensile strength and good tensile properties.
