Press-locked stainless steel
Press-locked stainless steel gratings are suitable for all industries in the food and petrochemical sector.
304 stainless steel is used solely for the food industry, whereas 316 stainless steel is used in environments regularly exposed to corrosive products.
Benefits of press-locked stainless steel gratings:
- Can be manufactured with single or double notching for use in slippery inside or outside conditions.
- For use for heavy loads, trucks or cars.
- Quick assembly with retaining fasteners.
- Safety : stainless steel gratings can be manufactured from strips with no sharp edges to ensure they can be handled without risk of injury.
Custom manufacture:
GEI can manufacture made-to-measure press-locked stainless steel 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.
Several finishes available:
- Untreated (welding points will be more visible and thus less visually appealing)
- Blasted
- Electropolished
- Anodised.
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
- Stainless steel 304 ( 1.4301 ).

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.
