STEEL SYSTEMS FOR ARCHITECTURE

Jansen develops steel profile systems for windows, doors, façades and sliding solutions. Based in Oberriet, Switzerland, the family-owned company has been developing solutions for construction and industry since 1923.

Steel combines high structural strength with slim profile dimensions, making it particularly suited to applications where large glazed areas, narrow sightlines or demanding performance requirements are important. Jansen systems cover thermally insulated and non-insulated solutions as well as systems for fire and smoke protection, burglary resistance and other security requirements.

The portfolio is used across new construction and refurbishment, from residential and commercial buildings to schools, hospitals, transport buildings and industrial architecture. For existing and listed buildings, slim steel profiles can also help preserve the original character while meeting contemporary performance requirements.

Alukönigstahl Partnership: As an authorized Jansen partner, we provide local technical consultation, project support, and fabrication expertise to ensure successful system specification and implementation across Austria and Southern Germany.
