Jansen AG is a family-owned company based in Oberriet in the canton of St. Gallen that develops, manufactures and distributes steel profile systems for windows, doors and facades, as well as plastic products for construction. It is a leading supplier of steel systems for the building envelope.

Its steel systems are characterised by slim profiles, high strength and fire-protection solutions, combined with aluminium systems distributed exclusively in Switzerland. The company supports architects, metalworkers and facade builders from design through to execution.
