Louvred Gratings
Der Lamellenrost wird hauptsächlich in der Architecture verwendet. Von Architekten wegen seiner einfachen Nutzung und des Designs geschätzt, ist der Lamellenrost zum wesentlichen Element bei der Fassadengestaltung geworden.
Er kommt im Neu- und Altbau zum Einsatz und verleiht Gebäuden ein ästhetisches Aussehen. Durch die im Allgemeinen 45° schrägen Lamellen, bietet der Lamellenrost einen exzellenten Sonnenschutz und durch die Luftzirkulation wird ein thermischer Komfort gewährleistet. Er kommt auch in der Industrie zum Einsatz. Die eingeschränkte Durchsicht verringert das Höhengefühl.
Louvred GEI grating is manufactured according to a precise load table. The dimensions of the bearing bars (BB) are important because they determine the load bearing capacity of the grating.
- 100 x 30 – 60 x 30 – 30 x 30.
- Other options are available on request.
Fastening systems are manufactured from galvanised steel for steel gratings and from stainless steel for stainless steel and aluminium gratings. In certain cases, gratings may be fixed to structures with welded brackets.
| Bearer Bar | 25 | 30 | 35 | 40 | 50 | 60 |
| Füllstäbe 45° schräg | 35 | 40 | 50 | 55 | 70 | 85 |

Manufacturing Principle
GEI louvred grating is characterized by transverse bars inserted at 45° into the bearing bars (please check with us for any other angle). It can then be produced in “flat” sections, welded at right angles to the bearing bars. The grating then optionally undergoes hot-dip galvanizing in accordance with the applicable EN ISO 1461 standards. G.E.I louvred grating is typically manufactured from EN 10025 standard S235JR steel which ensures a consistent production quality.

Mesh
Spacing between bearing bars (BB) and transverse bars (TB). Mesh created in this way has two characteristics: mesh width and mesh centre spacing (pitch).
- Mesh width: the width of the opening that is between the BBs and TBs
- Mesh centre spacing (pitch): the distance between the centre of BBs and TBs (for example, the distance between the centre of one bearing bar and the centre of the nearest adjacent bearing bar
Mesh group | Type
Mesh is made up of two values (in mm), where the first dimension is the distance between adjacent bearing bars, and the second dimension being the distance between adjacent transverse bars (for example: 33.33 x 33.33; 33.33 x 11.11; 55.55 x 55.55; etc.).
For convenience’s sake, the term “mesh gauge” is more frequently used (for example: 30 x 30 - 30 x 10 - 50 x 50 - etc.)
Bearing bars (BB)
Straight rods bearing the weight and arranged in rows at right angles to the transverse bars and supports.
Transvers bars or cross bars (TB)
Inserted at 45° into the bearing bars (contact us for any other degree of inclination), the BIs are assembled to the BPs by pressing.
BB and TB gauge
This is defined by two values (in mm), where the first corresponds to their height and the second to their thickness. Gauge examples: 30 / 2; 30 / 3; 40 / 3; etc...
Range
Gap between the supports on which the ends of the bearing bars rest.
Impermeability – security bars Sicherheitsmasche
Security mesh uses the following mesh gauge: 30 x 19; 19 x 30; 19 x 19; etc. It is recommended for industrial environments (14122 standard) and allows nothing exceeding a 20 mm diameter ball to pass through it.
Support braket
Bracket welded to the ends of the grating rendering it suitable for certain uses (for example: shelving, guttering).
Steel
Stainless steel
Aluminium
"Flat" banding bar
Bar which forms the outer frame of the panels.
Base panel
Straight metal welded onto the end of the grating
Toe plate
Straight metal welded onto the end of the grating
