          ICalculation of Deformation Under Stress of Economy Series Industrial Aluminum Frames
    Aluminum   Frames  When selecting economy series industrial aluminum frames, the deformation is an important basis for selection. The deformation of                                                  Frames  Aluminum
           aluminum frames under dead load and stress can be easily calculated using the following formula.
