What RHEINZINK does

RHEINZINK GmbH & Co. KG is a privately held German manufacturer of titanium zinc products for the building envelope, headquartered in Datteln in the Ruhr region and operating as a subsidiary of the Grillo Group. Founded in 1966, the company produces titanium zinc coils, sheets, and pre-finished surface variants (prePATINA ECO ZINC, CLASSIC, GRANUM basalte, GRANUM EXTRA, PRISMO, PRISMO brushed white+) at its German headquarters, and sells them exclusively through specialist wholesalers in over 30 countries across Europe, North America, Asia, and the Middle East. Application areas span three system categories: roof systems (including the double standing seam, angled standing seam, click roll cap, flat lock tiles, and the roof-integrated RHEINZINK-PV solar mounting system), façade systems (seam, panel, cassette, and surface design), and roof drainage (half-round, box, and internal gutters plus architectural details). Core technology rests on a patented pre-weathering process for prePATINA ECO ZINC and a phosphating-based surface treatment for the GRANUM line, both marketed on durability (80+ year lifespan), 100% recyclability, low maintenance, and natural patina development. RHEINZINK earns revenue through one-time material and system sales to specialist wholesalers (B2B), supported by direct technical services to architects and installers, including BIM data on the Polantis platform, sample ordering, training programs (including the RHEINZINK Masters competition), and a 40-year warranty on standing seam systems. Go-to-market is sales-led, targeted at architects and planners (primary specifiers), craftsmen and installers (installation and brand ambassadors), building owners (end beneficiaries), and specialist wholesalers (distribution channel). The company employs approximately 500 people internationally.
