Grauthoff

What Grauthoff does

Grauthoff GmbH & Co. KG is a family-owned German metalworking company (Metallbaubetrieb) founded in 1954, headquartered in Geldern on the Lower Rhine. The company designs, manufactures, galvanizes, powder-coats, and installs metal products with a primary focus on fence and gate systems, barrier and access control technology, and custom steel constructions. Its production facility spans approximately 2,500 sqm across two halls built in 1991 and 1998, employing around 20 staff plus 3 apprentices. The product portfolio is organized into fences (mesh, decorative, security, privacy, gabion, sports facility), gates (swing, sliding, custom), barrier and access control (posts with the proprietary DIN 3223 triangular lock, railings, turnstiles, barriers, access control), and architectural/garden metalwork (railings, stairs, raised beds, canopies, sculptures, corten steel).

The company's business model combines direct sales with full installation services alongside a nationwide channel network of construction firms, landscaping companies, and intermediate dealers across Germany. Revenue is generated from one-time product sales and professional installation services, with approximately 2 million EUR annual turnover from fence and barrier supply-plus-installation. Customer segments include private individuals, commercial enterprises, trade resellers, and government/authorities, with a notable concentration of public-sector and large venue projects (federal ministries, prisons, airports, stadiums, industrial sites). Go-to-market is sales-led with free on-site consultation and individualized quoting; no standardized public pricing exists. The company also resells complementary products from system manufacturers (Legi, Adronit, Betafence, Heras-SKS, Gunnebo).

The company's most distinctive technical asset is the Dreikantverschluss (triangular closure) for lockable barrier posts, invented in 1971 and codified as the DIN 3223 standard, which established Grauthoff's national reputation in the security barrier segment. Leadership currently rests with co-owner Franz-Josef Grauthoff alongside managing director Dirk van Bebber, who was granted Prokura in 2012 following the death of founder Josef Grauthoff in 2011. The company operates exclusively within Germany with no disclosed international expansion, no external funding, and no parent company.

Core offering

Grauthoff is a German metal fabrication company that designs, manufactures, and installs fences, gates, barriers, and custom metal products in its own ~2,500 sqm workshop in Geldern. The company handles the entire process from concept and CAD planning through manufacturing (with in-house galvanizing and powder coating) to on-site installation by its own trained personnel. Product categories span fence systems, gate systems, barrier/access control, railings/stairs, and metal garden/landscape products.

Product overview

Grauthoff is a traditional German metal construction company (Metallbaubetrieb) that manufactures fences, gates, barriers, and custom metal products. The company operates as a single unified product portfolio organized into product categories rather than a platform-plus-modules architecture. The core product range includes fence systems (Gittermattenzäune, Zierzäune, Sicherheitszäune, Sichtschutzzäune, Gabionen, Sportstättenzäune), gate systems (Drehtore, Schiebtore, Sondertore with Antriebstechnik automation), barrier/access control technology (Absperrpfosten, Sperrbügel, Drehkreuze, Schranken, Zutrittskontrolle), and metal garden/landscape products (Geländer, Handläufe, Treppenanlagen, Rankanlagen, Hochbeete, Überdachungen, Müllplatzgestaltung, Fahrradständer, Skulpturen, Cortenstahl). The company also offers Sonderanfertigung (custom fabrication) services for bespoke steel constructions. Products are delivered and installed for private customers, commercial businesses, trade partners, and government agencies throughout Germany.
