Press-welded grating for staircase steps
The Press-welded grating for staircase steps from GEI are manufactured with perforated, anti-slip nosing and sidewalls with standard or customized holes. GEI Staircase steps, können dank ihrer Sicherheitsmaschen und ihrer einfachen Rutschhemmung in der Industrie eingesetzt werden, lassen sich aber bestimmt auch für Ihre Projekte verwenden: zum Beispiel für straight stairs, as spiral Staircases or for Spiral Staircases.

Load tables
Press-welded grating is obtained by electrical welded transverse bars, which are usually square and twisted (but can be round and straight) into the bearing bars. The grating is produced with “flat” banding, and then optionally undergoes hot-dip galvanizing in accordance with the applicable EN ISO 1461 standards. For an optimised anti-slip surface, it is possible to produce serrated press-welded grating, with serration on the bearing bars only. It is typically manufactured from EN 10025 standard S235JR steel which ensures a consistent production quality. RAL-GZ 638 manufacturing tolerances applied.
