Steel stairs with all-glass railings | DSV Krefeld


The impressive stairs with all-glass railings in the corporate building of the global transport and logistics services provider DSV in Krefeld reaches over three storeys. The panels for the all-glass railings reinforce the impression of an open and light-flooded building. MetallArt, a specialist in the construction of demanding custom-made stairs, manufactured not only the imposing stairs but also the bridges, where the all-glass railings were used to intensify the experience of generous space.
