A support frame to be laid on a pair of cross-members of a shelf having at least two U-profile bars and C-profile bars extending transverse thereto and having flanges connected to the center webs of the U-profile bars. The space between the U-profile bars of the support frame is so dimensioned that the U-profile bars of the support frame just fit between the two cross-members of the storage shelf. The center webs of the C-profile bars are perforated, wherein at least some of the holes have rims protruding from the surface of the C-profile bars facing away from the U-profile bars.
