Advantages:

1, light weight, clear lines, insulation, strength, not easy to deformation.

2, the construction is convenient, not Qu Qiao, stripes tensile mechanical properties.

Disadvantages:

1, the general high cost.

2, the plywood is not as smooth as the density of the board, with the plywood to do the grassroots, the surface and then bonding fire board, aluminum panels and other decorative panels, as the density board to do solid base.

With the veneer after the wood by the direction of criss-cross the composition of the slab, in the heating or no heating under the conditions of suppression. The number of layers is generally odd, and few are even. Vertical and horizontal direction of the physical and mechanical properties of small differences. Commonly used plywood types are plywood, penta and so on. Plywood can increase wood utilization and is a major way to save wood.

The usual length and width specifications are: 1220 × 2440mm, while the thickness specifications are generally: 3,5,9,12,15,18 mm and so on. The main species are: camphor, willow, poplar, eucalyptus and so on.
