PRESSED-IN GRATINGS (PR)

Pressed-in gratings are manufactured according to DIN 24537. They ensure optimal lightweight structures with a good load bearing capacity, ease of assembly and superior appearance. The last feature permits employing the pressed-in gratings, irrespective of their basic task, as decorative architectonic elements. They are perfectly suitable for creating most complex communication facilities, yet they make up very aesthetic planes. The structure of the pressed-in grates features the so-called cold junction that develops as a result of the transverse flat bar being driven under a 100t force into the specially shaped recesses in the supportive flat bars.

The maximum dimensions of the pressed-in gratings: 2 200mm x 2 500mm. The basic opening is 11.1mm. The structural material is ST3S Al or equivalent. The gratings may be ordered in the corrosion resistant steel to the Polish Standard PN-71/H-86020 (0H18N9; 0H17N14M2 or H17N13M2T).
The gratings made from such materials may be applied in the agricultural and food and pharmaceutical sectors, as well as in hospitals and health facilities. The pressed-in gratings may be framed in flat bar or T-bar.

As agreed to by our Commercial Office, there is the possibility of having the pressed-in gratings delivered in the anti-slid i.e. serrated design. Such a design is advisable in locations particularly exposed to: oil spillage, snow, ice, and also within sloped communication passages.
In the event of platforms that are subjected to loads in varying directions it is advised to use the solid gratings, the so-called Kartonroste, where same stringers and transverse flat bars are applied.
In areas with heavy pedestrian traffic it is proposed to employ the pressed-in gratings with more openings (11.1mm) the dense gratings.
