Graepel-Steg
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
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

Conversion of the replacement load Fq from the table into a surface load Q
Q = 106 xFq
B x L
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]
