Strength tables
For a gap of a=34,3 mm
Table 3 shows loads for welded gratings with a graduation of a=34,3 mm and a distance between bars of 38.1 mm.

Table 3 – legend:
Fv – continuous load in daN/2,
fv – bend deflection from deflection Fv,
Fp – load concentrated on a surface of 200×200 mm, daN
Fv – bend deflection from deflection Fp,
For a gap of a=15,08 mm; a=30,15 mm
formula
Resistance of a grating with graduation of a=34,3 According to the table
x Index for the chosen graduation
= resistance of a grating with the chosen graduation
