In 1968, the rolling mill and the first shearing line were installed.

Just one year later, the semi-finished products plant came into operation (2nd picture). At the Datteln site, the new continuous wide-strip casting and rolling line began operations. RHEINZINK thus became a European pioneer in the manufacture of high-quality titanium-zinc products. Annual production capacity stands at 25,000 tonnes. It is Europe’s only horizontal wide-strip casting machine, purchased in the USA.
RHEINZINK employs 150 people.

RHEINZINK is continually expanding its international presence. New sales structures and branches are strengthening its ties with customers and partners. The company is evolving from a German manufacturer into a global provider of solutions for sophisticated architecture.

Two new melting furnaces and a new longitudinal forming line commenced operations in 1992. Also commissioned were the second 4-stage deep-drawing press, the second stage press, the 7th and 8th pipe-bend soldering machines, the third pipe soldering line and the expansion of the BuC line to two presses.

By the end of the 1990s, Grillo held a majority stake in RHEINZINK. The company acquired two-thirds of the shares. This permanently cemented the close ties with the family business and laid the foundations for its future development.

1 December 2005 – RHEINZINK became a wholly-owned subsidiary of Grillo Werke Duisburg AG.

After six months of construction, the villa designed by
star architect Daniel Libeskind is being inaugurated. It serves as a reception building.

In 2019, the Libeskind Villa provided an exclusive setting for the ‘Meine Welt’ vernissage, showcasing the works of Armin Müller-Stahl.

With PRISMO, RHEINZINK is expanding its portfolio to include a design-oriented product range featuring six distinctive surface finishes: red, green, brown, blue, gold and black.

In the same year, the digital training platform RHEINZINK-INTERACTIVE is launched.

Six decades of RHEINZINK have been characterised by technical expertise, architectural know-how and the commitment of partners, customers and employees. The change of ownership marks a milestone in the company’s history. It offers the opportunity to build on tried-and-tested practices whilst opening up new prospects for the future. In August 2026, Robus Capital acquired 80 per cent of the shares in RHEINZINK. The previous sole owner, GRILLO-Werke AG, retains a 20 per cent stake.
