What Zambelli does
Zambelli is a privately held German industrial group operating across six business units anchored on metal processing: roof drainage systems (including the registered COLORDUR® color-coated range), building envelope solutions (metal roofing and facade, traded under the RIB-ROOF brand), industrial metalworking (prototypes through serial production of sheet metal parts, housings, and assemblies), shelving and storage systems for libraries, archives, museums, offices, and warehouses, caravaning components for motorhomes and caravans, and heating-technology assemblies and complete heating systems. Manufacturing covers cutting, forming, powder coating, wet-paint finishing, and assembly in-house, with a stated 1,200+ employees distributed across six companies in Germany, the Czech Republic, Hungary, and Romania, and a dedicated caravaning competence center in České Budějovice.
The company's commercial model is B2B and sales-led, serving industrial customers (motorhome and caravan OEMs, heating-system manufacturers, industrial customers needing prototype-to-serial sheet metal), skilled trades (roofing and sheet metal professionals), and public-sector clients, supported by an international partner network for the roof drainage division and direct enterprise sales across the manufacturing footprint. Pricing is quote-based, varies by product, customization, and volume, and is not publicly disclosed; revenue is generated through hardware sales across all six units rather than licensing or subscription.
In August 2024 Zambelli added a solar-adjacency dimension through a partnership with HUBER Solarfix GmbH to launch the HSF Ballast Tank mounting system for photovoltaic arrays on flat roofs, alongside ongoing trade-fair presence (BAU 2025, DACH+HOLZ) and the 11th International Partner Meeting of the Roof Drainage division in Budapest and Györköny. The group is family-controlled under Zambelli Holding GmbH, with no disclosed external private-equity, venture, or public-market backing, and does not disclose revenue.
