Fast food tables and chairs outside with plywood subject to stringent environmental health treatment process, but also a reference to the scientific principle be manufactured to be able to put to use to improve. Among them, the most important is to respect the principle of symmetry. On both sides of the central plane of symmetry veneer bentwood chairs frame factory, whether species veneer thickness, number of layers, manufacturing methods, fiber orientation and moisture board should correspond to each other bentwood chairs rack outlets, namely the principle of symmetry plywood center plane both sides of the corresponding layers of equal size in different directions of stress, when the plywood to support its water content changes, structural stability, no distortion, cracks and other defects. Food, heat, as well as the process of using water to clean sweep so will result in changes that affect fast food tables and chairs Desktop deformation play an important stabilizing role of checks and balances, maintain a perfect appearance. The same principle odd layer structure is a very important principle. Since the structure of plywood veneer fiber direction of adjacent layers perpendicular to each other, they must comply with the principles of symmetry, and therefore it must be an odd total number of layers. Odd layer plywood bending maximum horizontal shear stress at the center of a single board to have greater strength. This course is capable of supporting the board to achieve the desired long life. Table Table restaurant design elements to consider the overall package, to maintain the natural posture, with chairs seating function increases, not only to support the lumbar backrest also supports the back, head, or can not maintain a natural posture, job function and strong chair is too low because the head No support will increase the burden on the back can not maintain a stable posture. The foot under the table should be left free access to space, space should thighs and feet under the table to determine the scope of activities. One of the important factors that affect the height of the chair to sit face features. Sit face the more powerful a bentwood chairs frame wholesale, take the higher side, increase rest function, sitting surface is reduced. Sitting surface and backrest angle and in any case not less than 90 degrees, and increases with increased functionality chair rest, often 100 to 110 degrees is appropriate.
