Specification

Plywood (be it any grade or type) is typically made by gluing several veneer sheets together. The veneers sheets are manufactured from logs of wood obtained from different tree species. You therefore will find every commercial plywood made from different species of veneer.
Commercial plywood is most widelyused plywood for interior purpose i.e. homes and offices. Commercial plywood is preferred in dry areas like living room, study room, offices, etc. It is most commonly used to make furniture, as wall paneling, for partitioning, etc. However, In case of areas where water contact is expected, using an waterproof i.e. BWR grade plywood is regarded to be the best.

Veneer Options

In order to improve the anisotropy of natural wood as much as possible and make plywood uniform and stable in shape, two basic principles should be observed in the structure of plywood: one is symmetry; Second, the adjacent veneer fibers are perpendicular to each other. The symmetry principle requires that the veneers on both sides of the symmetrical central plane of plywood should be symmetrical to each other regardless of wood properties, veneer thickness, number of layers, fiber direction, moisture content, etc. In the same plywood, veneers of single tree species and thickness or veneers of different tree species and thickness can be used; However, any two layers of symmetrical veneer trees on both sides of the symmetrical central plane shall have the same thickness. The surface backplane is allowed to be different from the same tree species.
