Sculptural steel staircase for the industry | Würth

2023, Munich

The red colour scheme and compact shape of the interior steel staircase for industry reflect the successful market presence of the global player Würth Elektronik.

Strong in colour and design

Würth Elektronik eiSos GmbH Co. KG opened the Hightech Innovation Centre (HIC) in spring 2023, further expanding its position in technological research and development as an internationally successful manufacturer of electronic and electromechanical components. The new building in Munich-Freiham offers space for around 250 employees and was realised as a state-of-the-art building in line with current New Work approaches. On the ground floor, processes and technologies in the areas of wireless connectivity, sensor technology and big data are being driven forward. The administrative area on the upper floors was equipped with staff offices. In the open-plan foyer, the steel staircase inside represents the company's strong market presence with maximum symbolism in terms of colour and design.

Sculptural steel staircase

The steel staircase leads up to the first floor for the industry and is also visible from the outside as a dominant sculpture in the characteristic red colour of the Würth Group. The continuous closed outer stringer also gives the structure its cylindrical shape and creates a separate area in the spacious foyer. The interior steel staircase for the industry, with its large façade and soffit panelling, forms a unique staircase body and, not least thanks to its homogeneous finish, marks the high level at which METALLART carries out the surface preparation and painting of sculptural staircases. This staircase project therefore offers a very special experience both from the outside and when walking on it from the inside.
