Press-locked gratings for staircase steps

JK Technic 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, JK Technic staircase steps are suitable for all your projects.

They can be used for straight staircases, balanced steps or even for spiral staircases.

Assembly

JK Technic 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. JK Technic press-locked grating is typically manufactured from EN 10025 standard S235JR steel, which ensures a consistent production quality. RAL-GZ 638 manufacturing tolerances applied.
