What MJ-Geruest does

MJ-Gerüst GmbH is a Plettenberg, Germany-based manufacturer of modular steel and aluminum scaffolding systems serving professional scaffolding firms (Gerüstbaubetriebe), construction companies, industrial service providers, and event-industry buyers. Founded over 50 years ago and operating as part of the JUNIOR Gruppe under managing directors Jörg Frommann and Stefan Quinckhardt, the company designs, engineers, and produces its systems in-house at its Plettenberg facility in North Rhine-Westphalia.

The product portfolio centers on six core scaffolding systems — OPTIMA (a stiel/pole-system with an integrated advance guard rail), UNI-CONNECT, COMBI, UNI 70/100, UNI TOP 65/100, and OPTI-BEAM — supplemented by the Wand und Dach enclosure system, system-free accessories, and service offerings including 3D scaffold planning and TRBS 2121-1 safety-compliance seminars. Systems are engineered for compatibility with common market standards so that customers can integrate MJ components into existing inventories. The flagship OPTIMA line is differentiated by a system-integrated advance guard rail (voreilendes Geländer) that addresses Germany's TRBS 2121-1 workplace safety regulation by removing the need for personal fall protection equipment during assembly.

MJ-Gerüst distributes via a Germany-wide external sales force (Außendienst) backed by a service hotline, online contact form, HubSpot-driven lead capture, and export channel partners in Austria, Switzerland, Serbia (UNIMAST DOO), Sweden, and other European markets. Marketing combines case-study content (MJ-Ortstermin), technical-tip content (MJ-Gerüstgeflüster), a multilingual website, social media presence on LinkedIn, Facebook, Instagram, YouTube, and WhatsApp Business, BAUMA trade-fair participation, customer seminars, and factory tours. Revenue is generated through one-time B2B product sales priced on a quote basis; second-hand materials are also distributed via the Kleinanzeigen marketplace. The company is expanding capacity through the EUR 14 million development of a new logistics center at the former DURA site in Plettenberg.
