Special types • all Graepel safety gratings are also available as flat banks without folded edges here, the maximum embossed field width must not be greater than 480 mm; these flat cuts have a slightly curved finish gratings can also produced with other dimensions (H/B/L) than those shown above gratings with unperforated edges or surfaces on one or both front surfaces are also possible we are at your disposal for further technical queries DD 11 mild DD 11 hot-galvanised/DX 51 D pregalvanised Stainless steel ENAW 5754 Lengths (L) to length divider* Widths (B) DD 11/DX 51 D Stainless steel Width divider* Heights (H) Stock dimensions see Material thickness This grating is distinguished by its pratical design and high load bearing capacity and is especially recommended for floor areas in industrial plants high load-bearing capacity with substantial advantages in steel construction the lateral system perforation simplifies the installation of the gratings the 16 mm high profiles in lateral grating direction permit high point loads approximately 28 % free perforated cross section for standard graiting widths considering length divider of 50 mm sawn through perforation unperforated edge at custom made possible * Grating length and width: please order standard dimensions which are divisible by the dividers mentioned in each case. Anti-slip values Test No. Length weight per meter Steg for material thickness S in [kg/m] Grating width [mm] 150 200 250 300 * values apply also for DX 51 D Conversion of the replacement load Fq from the table into a surface load Q whereby: Q = surface load for a grating [kN/m 2] Fq = replacement load from table with referance to the support width [kN] B = grating width [mm] L = support length [mm]

Lump load Grating width B [mm] 150* 200 250 300 Maximal possible lump load F [in kN] (numerical value apply for DD 11) Load area 200 x 200 mm Material thickness S [mm] 2.0 2.5 3.0 11.83 13.29 17.25 7.36 8.27 10.74 5.38 6.04 7.85 4.39 4.93 6.40 Note: The values are calculated for gratings which are supported over their whole length. For a given span width, the values stated in this lump load table must not exceed those given in the concentrated load tabel. For stainless steel the values in the table must be multiplied by a factor of 1.04 or for EN AW 5754 by a factor of 0.75. *For smaller...
