Frequently asked questions about this timetable

• NEN-EN-ISO 14122 – what does this mean and what does this standard say about GRP structures?

  NEN-EN-ISO 14122 is an internationally established ISO standard, which has been adopted within Europe as an EN standard and is published in the Netherlands as NEN-EN-ISO 14122. The standard describes requirements for fixed access systems, including:

  • landings,
  • stairs and stepladders,
  • ladders,
  • and handrails and guardrails.

  Together, these components form (within FlexxCon) a GRP construction.

  What does this standard say about GRP constructions?

  The standard provides guidelines for, among other things:

  • dimensions and angles of inclination of stairs and ladders,
  • minimum landing dimensions and clearances,
  • handrail heights, knee rails and fall protection,
  • ergonomics and safety during use.

  The assessment always takes place at the level of the total structure, not per individual component.

  Design responsibility

  If we manufacture exclusively on the basis of a design supplied by you, this design is not tested against NEN-EN-ISO 14122 as standard.

  Only if:

  • we also take care of the engineering phase, or
  • it has been explicitly agreed that the design will be assessed against NEN-EN-ISO 14122,

  can we confirm that the construction has been checked in accordance with this standard.
  In that case, this will always be clearly stated in the quotation or order.

  In summary

  • NEN-EN-ISO 14122 is a standard for safe fixed access
  • For GRP constructions, the following applies: the overall composition is decisive
  • Production based on a customer design is not automatically tested against the standard
  • Standard testing only takes place in the case of engineering or explicit agreement

  👉 Are you unsure whether a GRP construction must comply with NEN-EN-ISO 14122? Feel free to contact us — we will be happy to discuss this with you in advance.

• Do you also design GRP structures?

  We design GRP structures ourselves, but can also work based on your design. A design or sketch you provide can serve as an excellent basis for a quotation. When a project is further developed towards production, we usually create our own design.

  We do this for several reasons:
  • to ensure a good fit with adjacent structures and situations,
  • to establish structural principles,
  • and to draw up the component and assembly drawings required for our production.

  ⚙️ Drawings and file formats
  We draw in Tekla and AutoCAD, among other programmes, and can work with various file formats. This allows us to easily connect to the existing design, drawing or BIM model.

  Do you already have drawings available? Then we will gladly use them as a starting point. If things still need to be worked out or optimised, we will take care of that in consultation with you.

  👉 Whether you already have a complete design or are still in the design phase: we are happy to contribute our ideas and ensure a manufacturable, well-fitting GRP construction.
