What Jansen does

Jansen is a third-generation, family-owned Swiss manufacturer of architectural steel profile systems, headquartered in Oberriet in the Rhine Valley. Founded in 1923, the company develops, produces, and distributes precision cold-drawn steel tube and profile systems for doors, windows, facades, and folding/sliding applications, alongside a complementary plastics product line referenced in its corporate scope. Core products include thermally insulated and non-insulated steel door systems (in steel, stainless steel, and Corten steel), window systems, mullion-transom facade systems, and folding-sliding systems, sold as complete assembly packages rather than individual components. The technology stack centers on proprietary cold-drawn steel profiles, an in-house Technology Center for R&D and certified component testing, the JANIsoft 2D/3D planning software, BIM-compatible system models, and precision bent-steel capabilities. The company operates across six markets — Switzerland (HQ), the United States, the Netherlands/Belgium, Turkey, and China — through regional subsidiaries and representative offices.

The business model is built around project-based, custom-priced sales of complete steel systems to a fragmented buyer ecosystem. Primary customers are architects and architectural firms (as specification drivers) and metalwork fabricators (as installers), supported by a worldwide partner network of trained processing partners. Pricing is quote-based per project ('Prijsaanvraag' / price request), with multi-year contract cadences typical and no public rate cards disclosed. Beyond hardware sales, revenue is generated through technical consulting, custom bent-profile fabrication, and downstream services including BIM modeling, workshop design, and Technology Center testing.

Commercially, Jansen pursues an enterprise field-sales GTM anchored on deep engagement with specifiers: it runs the Jansen Academy for partner training, the Piet Boon by Jansen exclusive design series, a Virtual Showroom, the SCALE thought-leadership magazine, a Docu Center for technical documentation, and sustained presence at industry events such as the ZAK World of Facades. Recent moves include expanding into North America via Jansen America, Inc. (New York), releasing 8 Environmental Product Declarations (EPDs) for the US market in March 2026, and launching incremental products such as the Fastening Kit 499.025 and an extra-slim design handle line. The company is privately held by the founding family, with no outside institutional capital and no disclosed revenue figures.

Broad incumbents

• Kawneer: U.S. architectural aluminum systems company (part of Arconic) supplying curtain walls, windows, and storefronts; competes with Jansen's North American push in the same commercial and institutional specifier channels.
• Schüco: German global leader in aluminum (and steel) building envelope systems, competing with Jansen for the same architects and premium commercial projects but at much greater scale and with a broader product portfolio.
• Reynaers Aluminium: Belgian architectural aluminum systems provider serving commercial, residential, and renovation markets across Europe and beyond; competes for the same architect-specified facade and window projects as Jansen.
• Technal: French-origin aluminum architectural systems brand (Norsk Hydro) serving premium commercial and residential facades in Europe and internationally, with overlapping customer base of architects and fabricators.
• WICONA: European aluminum building systems brand (Hydro) targeting commercial facades, windows, and doors with BIM-driven specification tools—directly comparable to Jansen's BIM and JANIsoft-led specification strategy.

Direct peers

• Hueck: German manufacturer of aluminum and steel profile systems for windows, doors, and facades, with similar product breadth, custom-engineering services, and architectural specifier focus as Jansen.
• Raico: German manufacturer of steel and aluminum facade/window profile systems with strong curtain-wall expertise, comparable to Jansen in engineered steel fenestration for premium and commercial building envelopes.
• Forster Profilsysteme: Swiss-headquartered manufacturer of steel and stainless-steel profile systems for doors, windows, and facades, making it the closest direct peer to Jansen in product, geography, and target market (architects and high-end projects).
• Vitrocsa: Swiss minimalist slim-frame window and facade systems manufacturer; comparable to Jansen as a Swiss-rooted, design-led, premium fenestration brand serving high-end residential and iconic commercial projects.

Regional players

• Aluprof: Polish aluminum systems manufacturer with growing Western European presence, supplying windows, doors, and facades to commercial and residential projects; overlaps with Jansen's European specification market but with a cost-leadership positioning.
