  1. U - safe and uniformly distributed load,KN/㎡;D - deformation deflection, mm.
     
  2. The dead weight in table is calculated based on untreated plate. After making such procedure treatments as enclosure and hot dip galvanizing, the weight per square meter of steel grating after deep processing will be increased by at least 12% to 16% compared with that of untreated plate shown. The increased weight percentage for each type is different. The increased weight of hot dip galvanizing is calculated based on 7%.
