Staircase steps
GEI press-welded staircase steps are manufactured with a non-skid perforated nose and lateral covers with standard piercing or custom piercing on request. Used in industrial fields for their security mesh and without single notching (on request), GEI’s staircase steps are suitable for all your projects. They can be used for straight staircases, balanced steps or even for spiral staircases.

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.
