The variable railing system

Guardrail System BARRIER


When accessing areas at height, edges (such as roof edges, working platforms, etc.) represent a danger area.


One option for securing this danger area, both for construction work and for later servicing and maintenance tasks, consists of installing a guardrail system. As collective protection, the BARRIER guardrail system solves this problem by eliminating the danger which results from an edge.

  • Universally usable thanks to variants held by superimposed load or by fixed attachment to structural components
  • Economical thanks to rapid installation through wide post separations
  • Robust because of weather-resistant aluminium railings - 100 % plasticiser-free
  • Colour can be harmonised by means of surface anodisation
  • Easy to retrofit because of low weight-loading on flat roof
  • Flexibility through compensation of differences in roof level up to 12.5 cm
  • Railings can be inclined at 90° and 75°
  • Certifications to the latest state of the art:
    EN 13374:2019
    DIN EN 14122-3:2016
    DIN 14094-2:2017
