Staircase steps
The Press-locked stair treads from GEI are manufactured with perforated, anti-slip nosing and sidewalls with standard or customized holes. GEI Staircase steps, which are used in industry for their safety mesh and their single or double anti-slip properties and in public areas for their aesthetics and surface quality, can certainly also be used for your projects: for example for straight stairs, as spiral Staircases or for Spiral Staircases.
Piercing intervals
Depending on the specifications, numerous standard piercing intervals are available and any other piercing is available on request.| Steps

Assembly
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.xxx
