Jansen AG is a family-owned company that develops, manufactures and distributes steel profile systems for windows, doors and facades as well as plastic products for the construction industry. It was founded by Josef Jansen[2] in 1923, starting with 6 employees.[3][4]

The company started producing steel pipes in 1930. In 1955, plastic tubes were added to the range of products. Today, the plastic product portfolio includes systems for geothermal energy,[5] building technology and piping systems. In 1997, a first new production site outside Switzerland was established in Dingelstädt, Germany.[6] In 2021, Jansen AG decided to focus on steel products for windows, doors and facades, spinning-off its supplies for the automotive industry to Mubea.[7]

As the exclusive licensee of Schüco in Switzerland and Liechtenstein, Jansen also offers architects and processors solutions made of aluminium.

In 2023, Jansen AG acquired Rino Weder AG, a company located in Oberriet SG as well. Through this acquisition, powder coating technology was added to its capabilities.[8][9]

Jansen AG was able to celebrate its 100-years anniversary in 2023.[10]

Since its beginning, the Jansen Group is 100% family-owned and employs 2024 around 600 people internationally.
