Stahltreppe innen für Industrie

Steel stairs for the industrial sector

Perfect match

The red colour and the compact appearance of the interior steel stairs for the industry correspond to the strong market position of the global player Würth Elektronik.

Project description

Powerful colour and design

In spring 2023, Würth Elektronik eiSos GmbH Co KG opened the Hightech Innovation Centre (HIC) in München-Freiham. As an internationally successful manufacturer of electronic and electromechanical components, the company is thus further expanding its position in technological research and development. The new building offers space for around 250 employees and was realised as a ultra-modern facility based on the latest 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 offices for employees. In the spacious foyer, the steel stairs for the industrial sector represent the company’s strong market profile with maximum symbolism in colour and design.

Sculptural steel stairs for industrial sector

Leading up to the first floor, the steel stairs are a dominating sculpture in the characteristic red colour of the Würth Group and are also highly visible from the outside of the building. The entirely closed outer stringer also emphasises the cylindrical look of the structure and creates a separate area in the open-plan foyer. With its large facade and soffit cladding, the steel stairs form a unique staircase body and, not least thanks to its homogeneous finish, demonstrates the high level of surface preparation and painting that MetallArt carries out on sculptural stairs. Both the outside and the inside of this staircase project offer a very special type of experience.
