RHEINZINK architectural zinc

Versatile, long-lasting and
environmentally friendly

Zinc has been a very versatile metal used in constriction for generations.  For optimal results, it is best to use RHEINZINK architectural zinc. RHEINZINK architectural zinc consists of 99.995% pure primary zinc with a small portion of titanium and copper.  This alloy is easily shaped, long-lasting and corrosion-resistant.

Freedom of design combined with lasting beauty

RHEINZINK architectural zinc allows design freedom not always possible with other materials.  The RHEINZINK alloy composition provides the necessary strength, while allowing the product to be easily shaped into complex profiles.

Our material can be fabricated into complicated details for a multitude of shapes.  The appearance of our architectural zinc enhances the entire building, whether used for roofing, roof drainage and gutters, dormers and gables, or balcony, chimney and wall cladding.

Sustainability with low-to-no maintenance

Virtually all architectural zinc in use can be recycled, an infinite number of times, with low energy consumption, and without producing any polluting emissions.  Over time, a protective patina develops and gives zinc both its evolving aesthetic and its incredibly long service life.

Worldwide, historic buildings’ zinc roofs have endured for 100 years and longer, demonstrating zinc’s high performance and low-maintenance resilience.  Moreover, every RHEINZINK product we make today consists of 30% recycled material.  Further information is available under Sustainability.

Our material: RHEINZINK architectural zinc

RHEINZINK® is a brand name for architectural zinc manufactured in accordance with DIN EN 988.  The basic alloy consists of electrolyte primary zinc with a 99.995% purity degree in line with DIN EN 1179.  Small, precisely defined quantities of copper and titanium are added to the alloy.  The alloy composition is significant for the material's performance properties along with other factors, such as RHEINZINK prePATINA's coloration.

The raw material is smelted, cast as a material of uniform and certified quality and, wound as a coil in one continuous operation.  RHEINZINK’s architectural zinc coils are further fabricated and manufactured into roofing, roof drainage and gutters, or wall cladding and façade systems.
