When planning a production hall for punching technology and assembly at Rosenberger, the focus was also on a floor plan that could be used as freely as possible. Rosenberger Hochfrequenztechnik, a medium-sized, family-owned industrial company, was founded in 1958 and is now one of the world's leading providers of connection solutions in high-frequency, fiber optic and high-voltage technology, including for the automotive and telecommunications industries, medical and industrial electronics and industrial measurement technology. More than 2,000 employees work at the headquarters in Fridolfing, and the Rosenberger Group employs around 10,000 people worldwide at numerous production and assembly sites and sales offices in Europe, Asia and North and South America.

Adaptable layout sought
The new assembly center in Fridolfing needed to offer maximum space for the production machines and allow an efficient material flow. What is stamped on the first floor of the production building is to be assembled into finished connectors one floor above in the assembly hall. A versatile layout was important here in order to be able to react quickly to future production changes.

These requirements had to be harmonized with an appealing architecture, as the new building is part of a corporate architecture concept for a completely new part of the plant, consisting of various office, production and logistics buildings. The concept was developed and implemented by the architects of industrial construction specialist Hinterschwepfinger, who were able to reconcile all aspects and meet the various requirements with the Kielsteg elements.

The roof of the hall was constructed using 2,300 square meters of timber construction elements. Elements up to 19.7 meters long were used as single-span beams, so that the three-bay hall, measuring approx. 56 by 53 meters, only requires two rows of central columns. As the components are only 61 centimetres high despite their enormous structural capacity, the planners were able to construct the two-storey building as a comparatively flat structure that blends in perfectly with the overall appearance of the existing site.

What is coherent from the outside has a balanced effect on the inside. For large halls where many people have to carry out different tasks, not only is logistical planning essential, but also a well thought-out visual and acoustic spatial effect from the outset. Here, the surface-forming roof components prove to be an advantageous design element, as they create a pleasant atmosphere in both respects with their closed timber soffit.

The two outer bays, designed as a single-span system, are each spanned by up to 19.70 meter long, slightly elevated elements of type KSE 610/57/93. While an office complex was installed on one side, the area at the other end of the hall is reserved for various purposes. The middle section, in which a large assembly area has been created, was designed with a shed roof system for intelligent daylight utilization.
