Load table for GRP gratings

 Load  in  kN/m2   (Conversion in Kg/m2: x 100)      -       stress limit: fd
 Application limit:  max. deflection < L/200  (0,5 % of the length of the gratings) or
  max. deflection < L/400  (0,25%  of the length of the gratings) 


The table values are theoretical values
