Newel stairs at the new
Axel Springer building

On a surface area of 52,000 m², the futuristic new building of the Axel Springer Group offers space for more than 3,000 employees. The interior inspires with a light-flooded, 45 m high atrium with terraced levels over 13 floors, which are connected by bridges. A special highlight are the extraordinary and spectacular newel stairs by MetallArt Treppen GmbH.

Newel stairs with distinctive design

The rounded newel stairs in the new Axel Springer building in Berlin feature an imposing design. Starting on the first floor, they extend upwards over two floors with a continuous tubular steel column and parapet-high stringers on the outside. The stability is provided by the central column attached to the concrete slab and the connections via the respective landings as well as transversal supports on the load-bearing bridges. The design of the steps in a folding construction meets the current trend. As a result of the accurate grinding and the perfect filling of the visible weld seams, the newel stairs create an absolutely homogeneous appearance. The MetallArt team used only materials that correspond to the standards of the German Society for Sustainability (Deutsche Gesellschaft für Nachhaltigkeit e. V.).

Project details

Design stairs featuring a tubular column

  • Stair diameter approx. 3,865 mm
  • Steps 42 pc.
  • Stringer thickness approx. 10-12 mm or according to structural requirements respectively
  • Stringer height approx. 1,470 mm or divided in approx. 1,120 mm
  • Diameter of the central column approx. 406 mm
  • A flush and exactly shaped steel soffit lining provides for structural advantages
  • Handrail: Tubular stainless steel handrail in timeless design on both sides of the newel stairs, diameter 42 mm
  • Handrail support with a diameter of 12 mm, lateral stainless steel round bar and flat steel shape cut bracket
  • Additional layer between the bulb plate and the steel steps to ensure absorption of the footfall sound

Access for assembly

As the access opening no longer corresponded to the size of the stair sections during the insertion of the newel stairs, subsequent changes had to be made. A complex sectioning of the stair parts and the on-site assembly was necessary. This required, among other things, all the balustrade stringers between the steps and the top edge to be interrupted, rolled separately and welded on site.
