Plywood is made from wood veneers glued together. First logs rotary cut into veneers or timbers plane cut into thin wood, and then with adhesive glued together into three or more layers of thin sheet. Usually with an odd number of sheets, and the fiber direction of the adjacent sheets are aligned vertically to each other. From the structure, the outer layer of plywood is called the outlayer, the front panel is called the face and the reverse panel is called the back.
Plywood is used according to grade,
The first class is used for advanced building decoration, high-level furniture and various electrical shells;
The second class is used for furniture, ordinary buildings, vehicles and ships decoration;
The third class is used in low building decoration and packaging materials.
1. Furniture
Plywood is the main material of furniture like cabinets and wardrobes. It is the body material for most available wood furniture such as sofa, vanities, and wooden doors.
2. Flooring
Multilayer flooring uses marine plywood as flooring base. The marine plywood is more stable in size than solid timber panels.
Flooring made with plywood is easier and cheaper to install than solid timber flooring, which requires expensive floor keel to install on the ground.
3. Formwork Material

Film Faced Plywood
Film faced plywood is part of the formwork system. It gives support to the concrete and makes a slab or wall out of the concrete pour.
FFP plywood and HDO faced plywood are massively used in highrise building frame construction. There are also steel or aluminium formwork panels, but plywood is more acceptable now in the business. Because wood based form panels are lighter than steel formwork panels.

LVL Plywood Beams
LVL is short for laminated veneer lumber. It is actually a plywood which resembles lumber. LVL has the same structure with plywood because it is also many layers glued together by adhesive.
LVL beams give support to film faced plywood in the formwork. It comes with a length of 1.8m, 2.4m, 3.6m, 4.8m, and 6m.
Most formwork beams are made with pine veneer for its stiffness and light weight.
4. Roofing, Walls, Subfloor
In western countries, many houses are build with plywood, OSB and LVL. Roofing panels are structural grade to make sure they can stay permanently in the structure.
Underlayment Plywood For Flooring
Structural plywood is the strongest performance plywood in the market. It features a WBP phenolic bond which can glue the veneers permanently.
Tongue and grooved plywood is a good material for subfloor and flooring underlayment.
5. Packaging Material
Plywood is widely used as commercial cargo packaging material. Machinery and many other things transportation reply heavily on plywood boxes. The plywood boxes are manufactured with plywood board, LVL timber, solid timber, and fasteners.
The benefit of using a plywood box to export your cargo is that it is fumigation-free.
