ANTI-SLIP GRATINGS




Anti-slip gratings (serrated) are made of serrated load bearing and/or cross bars. Serrated gratings are used primarily for landings whose slope is larger than 6 degrees and platforms exposed to icing or contamination with oil and grease. Anti-slip features are provided by designed serration of flat bars during product processing. Slip resistance index depends on the orientation of serrated bars in a grating and direction of traffic. The value of this index is regulated by DIN 51130 standard.

GRATINGS SERRATED - TYPES

serrated_grating_s1
  • pressed grating serrated S1 - anti-slip bearing and plain cross bar
    - thickness of load bearing bars: 2 or 3 mm
    - mesh size as per the manufacturing plan
    - spacing of 33 or 44 mm: between the cross bars
serrated_grating_s2
  • pressed grating serrated S2 - anti-slip bearing and cross bar
    - thickness of load bearing bars: 2 or 3 mm
    - mesh as per the manufacturing plan
    - spacing of 33 or 44 mm: between the cross bars
serrated_grating_s3
  • pressed grating serrated S3 - anti-slip cross and plain bearing bar
    - thickness of bearing bars: 2 or 3 mm
    - mesh as per the manufacturing plan
    - spacing of 33 or 44 mm: between the cross bars
serrated_grating_s4
  • welded grating serrated S4 - anti-slip load bearing and twisted rod
    - thickness of bearing bars: 2 or 3 mm
    - mesh size as per the manufacturing plan
    - spacing of 38 or 51 mm: between the twisted rod

Anti-slip gratings should be selected with the following criteria in mind:
  • platform or driveway slope
  • environmental (atmospheric) conditions
  • presence of contaminants and their type
  • traffic direction with respect to the orientation of flat bars in a grating
