The distance between bearing bars or cross bars.
The first measure means the distance between bearing bars.
This measurement means the pitch of bearings bars or cross bars.
The bearing bars are the main elements of the gratings. These are the load caring bars which are made from steel, aluminium or stainless steel strips
or extruded metals. Bearing bars always should span between the supports.
Cross bars connect the bearing bars in intended distances.
Usually they have a smaller dimension than the bearing bars.
The span ist he measurement between the supports in bearing bar direction.
Supports of gratings are usually the base of bearing bar ends.
Gratings should lay on the same surface as the gratings height.
Cuttings or cutouts are an area of grating removed to clear an obstruction
for pipes or aggregates crossing the surface.
Borderings are usually welded around the grating or along a cutting to avoid
the danger of insure or damage. Also borderings makes the gratings stabile.
Our tolerances orientate themselves according to the RAL GZ 638.
