Aluminium
Press-locked aluminium gratings are suitable for all industries in the food and chemicals sector but are also highly appreciated by architects for their matt appearance and even finish. They can be used as façade boarding, industrial floors and floorings and even as sun-breaker and false ceilings. verwendet, als Fassadenverkleidung, Industrieboden und Platten, als Sonnenschutz und für abgehängte Decken.
Benefits of press-locked aluminium gratings:
- Lightness: Aluminium gratings weigh 1/3 as much as steel gratings. They can thus be used in false ceilings, for façade coverings and for industrial floors and floorings.
- Available in standard mesh (e.g. 30x30) and security mesh versions (19x19 30x19, retains bearings of 20 mm).
- Can be manufactured with single or double notching for use in slippery inside or outside conditions.
- Quick assembly with standard or custom retaining fasteners.
Several finishes available
- Untreated
- Blasted
- Anodised.
- Powder-coated
Custom manufacture:
GEI can manufacture made-to-measure press-locked aluminium gratings to meet your requirements (layout, size, etc.). They are also available as panels and as straight or spiral staircase steps with non-skid noses and lateral covers. A range of meshes are available depending on your requirements.
Mesh
The mesh spacing is defined in accordance with the standards and loads that must be respected:
- For a BB thickness of 2-3 mm:
The BB spacing is typically a multiple of 11.11.
The IB spacing is typically a multiple of 11.11. - For a BB thickness of 4-5 mm:
The BB spacing is typically a multiple of 18.
The IB spacing is typically a multiple of 17. - Other options are available on request.
Bearer Bar
- Standard height: 20-150 mm.
- Standard thickness: 2-8 mm
- Other options are available on request.
Transverse bars louvred
- Standard height: 10mm
- Other options are available on request.
Dimensions
- Maximum length of bearer bars: 4000 mm.
- Maximum length of spacers: 2000 mm.
Material
- AlMg3 aluminium.
Surface Treatment

- Anodised.
- Other options are available on request.
Finish
- Available with 'T' or 'flat' edge.
- Available with single or double notching on request.
- Half-moon or sawtooth notching available.
Finished Product

GEI press-locked grating is characterized by transverse, cross bars inserted under high pressure into pre-existing notches in the bearing bars. This grating is produced in “flat” or “T”-shaped sections, welded into place and then optionally undergoes hot-dip galvanizing in accordance with the applicable EN ISO 1461 standards. For situations with an increased risk of slipping, anti-slip grating can be produced, where the upper surface of the bearing bars and/or the transverse bars can be given anti-slip serrations. GEI press-locked grating is typically manufactured from EN 10025 standard S235JR steel, which ensures a consistent production quality. RAL-GZ 638 manufacturing tolerances applied.
