Staircase steps
G.E.I press-locked staircase steps are manufactured with a non-skid perforated nose and lateral covers with standard piercing or custom piercing on request. Used both in industrial situations by virtue of their security mesh and their single or double notching and in public locations owing to their visual appeal and finishes, G.E.I staircase steps are suitable for all your projects. They can be used for straight staircases, balanced steps or even for spiral staircases.
Piercing intervals
Depending on the specifications, numerous standard piercing intervals are available and any other piercing is available on request.| Tread width in mm |

Several finishes available
- Untreated steel
- Power-coated steel
- Galvanized steel
- 304 or 316 stainless steel untreated, blasted or electropolished
- Aluminium untreated or anodised
- Corten steel
Custom manufacture
GEI can manufacture made-to-measure steps to meet your requirements (layout, size, etc.).
Our research department is available to handle your technical requirements and your intended layouts, and can advise you on issues up to and including the realisation of your orders.

Load tables
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.
