Facade steel systems are completely insulated systems of glazing bars, with thermal protective construction.

Facade steel systems are completely insulated systems of glazing bars, with thermal protective construction.

Whether it is a new construction or renovation of an existing building, facade steel systems and roof glazing can be performed using only a few modular components. This allows architects and designers to meet different requirements for thermal and sound insulation, as well as fire protection, while achieving a fully integrated design look of the entire building. In order to achieve an efficient structural design of steel facades, steel facades offer different load-bearing systems: fully supported spans, built-in single-sided or continuous beams. The use of welded structures enables the production of complex tailored elements and shapes, precisely and according to requirements. Steel facade systems have been tested in accordance with product standard EN 13830.

What began in 1923 as Josef Jansen’s craft workshop in Oberriet developed into a high-tech company operating in the international market. In doing so, typical Jansen values have been retained. The pioneering spirit of that time is also reflected in today’s products and services.

Today, Jansen AG manufactures and sells welded and drawn precision steel pipes as well as steel and stainless-steel profile systems for windows, doors and facades, and pvc products for construction, as well as industry: products that guarantee Swiss quality, innovation, longevity and energy sustainability. To this day, the Jansen Group has remained in 100% family ownership and employs about 1,000 associates internationally, of which approx. 60 studies the craft.

This Swiss family business generated a turnover of 285 million francs in 2013. Around the world, Jansen is active through representative offices and partner companies.

The production facilities in Oberriet and Dingestädt (D) process 300 t of raw materials per day, which roughly corresponds to the weight of an Airbus A 380. That is, if all the pipes, which Jansen produces annually, were connected, the earth’s equator could be encircled twice.
