CONZEN

What CONZEN does

Conzen Bilderrahmen GmbH is a family-owned picture frame manufacturer and framing services provider headquartered in Düsseldorf, Germany, founded in 1854 and currently operating in its fifth generation under Cecilie Kaimer-Conzen and co-manager Armin Mittermeier. The company manufactures bespoke picture frames across four core product lines — gilded frames (over 2,000 designs with real gold and silver leaf), natural wood and molding frames, antique frame replicas (faithful historical reproductions drawing on the 'Sammlung Alt Düsseldorf' historic collection), and metal frames — alongside professional framing services for paper works, paintings, photographs, and objects, including conservation-grade framing using acid-free, reversible mounting materials and UV-protective glass.

The business operates a vertically integrated manufacturing model: an open frame manufactory and showroom at Fichtenstraße 56 in Düsseldorf, a wholly-owned molding and frame production subsidiary (F.G. Conzen Leisten und Rahmen GmbH, founded 1990) in Burg bei Magdeburg, and a glass subsidiary (F.G. Conzen Glas GmbH). Technical capabilities include large-format passepartout cutting up to 304 x 154 cm via a VALIANI precision machine, in-house joinery for oversized stretcher frames, and skilled gilding with 23-karat gold leaf, Poliment preparation, and antiqued patination. The company employs approximately 20 gilders, framers, and art historians with multi-decade tenures.

Revenue is generated through custom one-off frame manufacturing and sales, project-based professional framing services, restoration of antique frames and artworks, art installation and transport services, and wholesale of model frames to specialist dealers across Germany. Pricing is quote-based, not publicly listed, and varies with frame type, dimensions, materials, and conservation specifications. Customers include private collectors, contemporary artists, museums (notably Museum Kunstpalast Düsseldorf), commercial galleries (Galerie Beck & Eggeling since 1994), cultural institutions (Kunstakademie Düsseldorf, Deutsches Fotoinstitut), and specialist framers. Distribution combines a direct Düsseldorf showroom with a wholesale dealer channel managed via the Burg subsidiary. The company is a member of Deutsche Manufaktur and carries the 1880 'Königlich Preußischer Hoflieferant' royal court supplier designation.
