With the Granum range, Rheinzink puts the spotlight on matt zinc

The result of sophisticated technology

The properties of Skygrey and Basalt zincs have evolved and have been optimized for greater appearance stability and better profiling properties. The matt surface, obtained by a high-tech treatment, lets show through, in a perennial way, the typical grain of zinc. An aesthetic and technical asset suitable for both renovation and new construction. The range requires no maintenance and is a durable solution for all areas of application. RHEINZINK, the world's leading manufacturer of zinc-titanium for the building industry, completes its range of zinc surface aspects with GRANUM, a range dedicated to matt zincs.

Wide areas of application

GRANUM zincs have many applications: in roofing, cladding, architectural details or in the evacuation of rainwater. Small areas are reinforced by these new colors and stand out clearly. Combined with other materials such as natural stone, wood or glass, they thus produce a clear artistic and architectural contrast harmonizing design and tradition.

Two subtle nuances

New range of surface appearance proposed by RHEINZINK, GRANUM brings together two subtle shades responding to current architectural trends:

• The Skygrey shade has a traditional matt gray appearance similar to the patina formed over time in nature by natural zinc.
• The Basalt shade, dark gray bordering on black, follows the current trend in surface architecture.

GRANUM completes the range of surface aspects offered by RHEINZINK:

CLASSIC: the most original form of the material variants. Under the influence of climatic conditions, a typical gray-blue patina is formed over time on its shiny metallic surface.

prePATINA: the only truly pre-patinated surfaces in the world. Only RHEINZINK has the “pre-patina” process which makes it possible to obtain, from the factory, the gray-blue or gray-slate tint of a natural patina without resorting to phosphating, coating or lacquering.
