DESIGN STAIRS WITH ALL-GLASS RAILING

Design stairs at the Steelcase Learning + Innovation Center Munich

Even from the outside the large floor-to-ceiling-windows allow a view at the central element in the foyer of the Steelcase Learning + Innovation Center in Munich: The design stairs with parapet-high box-type stringers by MetallArt. The international manufacturer for furnishings for healthcare, education and office facilities opened its first Learning + Innovation Center (LINC) in Europe in November 2017. By an optimized working environment the LINC aims to improve the information flows and the decision making processes in order to increase the efficiency of its staff. On a floor area of 14.400m² approximately 240 employees from 25 countries are working in the office building.

Design stairs for the LINC in Munich

The spiraled design stairs with its modern appearance blend harmoniously in the light-flooded foyer room. The flight of the stairs tapers from the stair foot to the stair head and even the box-type stringers show a conical design. At the stair foot the height of the stringers amounts 1,100 mm. At the stairs head it shows a reduced height of 300mm running from the top of the unfinished floor. With an additional pillar, consisting of a steel tube, the experts of MetallArt supported the outer stringer of the design stairs from below and fixed it at the existing concrete column.

Design stairs with landing and bridge

  • box-type stringers on both sides made of welded rectangular H-profile sections to accomodate the all-glass railings
  • Flight width of the design stairs at the stair foot on the ground floor; in the middle of the glass railing: 2,350mm
  • Flight width at the stair landing on top; axis GJ; in the middle of the glass railing: approx. 1,500mm
  • 17 risers
  • combined folded and box-type treads made of 5-6mm thick steel sheet or according structural requirements
  • Stair cover was supplied and fitted by the customer

Not least because of the all-glass railing in white glass (executed with a special glazing reduced in iron oxyd portion and therefore showing less visual green cast), placed onto the box-type stringers, the design stairs present a remarkable architectural hightlight at the LINC.

All-glass railing for design stairs

  • Panes made of laminated safety glass
  • Railing running both sides of the design stairs
  • Stainless steel U-section as handrail (approx. 40 x 30 mm)


A round steel tube with a diameter of 42mm was fixed laterally at the inner stringer of the design stairs. It serves as handrail for the design stairs.

Another significant detail of the design stairs is the structural supporting underside cladding consisting of steel sheet. Matching the stairs flight MetallArt welded precisely designed steel sheets on the bottom part, evenly between the stringers of the design stairs. The surface of the steel cladding was supplied with a primary coat to be finished with a lacquering on site.  

Directly at the head of the design stairs MetallArt installed a bridge which corresponds to the construction of the tread steps. It is however equipped with additional transverse ribs and steel sections between the stair stringers (number and dimension of the sections according structural needs). Another all-glass railing with laminated safety glass panes completes the bridge. It has however a uniform height and a top-attached stainless steel handrail. 


MetallArt provided for the verifiable structural calculation for the design stairs and the glass railing. Beside the listed positions the company supplied furthermore a straight all-glass railing for the gallery,  saw-tooth stringer stairs, stairs featuring a pale railing as well as a stringer staircase with mesh treads.
