MANUAL - Lichtgitter GmbH

Standard Programme
The flexibility of our production lines allows
the fabrication of a large variety of
different types of pressure-locked gratings.
It is possible to choose for example
a square pitch within the range of
pitches. A change is also possible within
the basic pitches, e.g. bearing bar
pitch 22,22 mm, cross bar pitch 33,33
mm. However, the maximum pitch for
pedestrian gratings of approx. 33 x 50
mm must be considered according to
the instructions of the professional associations.
Depending on the grating type the
height of the cross bars diversifies between
10 mm and 20 mm and of the
thickness between 1,6 mm and 3 mm.
Types of pressure-locked gratings
Fabrication procedure (pressure-locked
gratings), bearing bar, pitch and binding
are denoted by type designation.
Serrated pressure-locked gratings are
indicated by an „X“ before type desigantion
(e.g. XP 330-33-3)
Full cell gratings
Full cell gratings (gratings with bearing
bars and cross bars of the same dimension)
can be used as decorative elemets,
e.g. for ceilings, handrails and
sunprotection. Full cell gratings can be
produced up to a material thickness of
3 mm and up to a maximum height of
60 mm, depending on pitch .
