Hünnebeck staircases

Stable, sturdy and convenient staircases

They are essential on many scaffolds and elsewhere on construction sites to enable workers to get to and from their place of work at height. Our range of staircases are suitable for both professional trades and members or the public. The inherent variability allows ascending/descending stairs and other modes of access of all kinds and dimensions to be quickly assembled from just a few system components. Typically designed and integrated into the main scaffold, the staircases provide a convenient, fast and effective method of evacuation from a building in the event of an emergency.

The type of stairs will depend on the respective situation, the necessary height and the required load. We offer scaffold stairs, stair towers, construction stairs, and emergency stairs. We can also supply public access staircases which are designed to meet the latest legislation. For all versions, we supply complete kits including parts lists and static stability calculations for the standard versions.
