The size of the plywood used for the roof is usually 1220*2440mm

The usual length and width specifications of plywood are: 1220×2440mm, and the thickness specifications are generally: 3, 5, 9, 12, 15, 18mm and so on. The main tree species are: camphor, willow, poplar, eucalyptus, etc. Plywood is a three-layer or multi-layer board-like material made of wood pieces that are peeled into veneers or sliced into thin wood from wood, and then glued with adhesive. Usually, odd-numbered veneers are used and adjacent layers of veneers are used The fiber direction is perpendicular to each other and glued together. [1] Plywood is one of the commonly used materials for furniture. It is one of the three major panels of wood-based panels. It can also be used as a material for aircraft, ships, trains, automobiles, buildings, and packaging boxes. A group of veneers is usually formed by gluing the adjacent layers of wood grains perpendicular to each other. The surface board and the inner board are usually arranged symmetrically on both sides of the central layer or the core. A slab made of glued veneers crisscrossed in the direction of the wood grain is pressed under heating or non-heating conditions. The number of layers is generally odd, and a few have even numbers. The physical and mechanical properties of the vertical and horizontal directions are relatively small. Plywood can improve the utilization rate of wood and is a main way to save wood.
