RHEINZINK titanium zinc: Versatile, lasting, ecological

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

Freedom of design combined with a visual upgrade

In addition, RHEINZINK titanium zinc allows design freedom that is not always possible with other materials.  The RHEINZINK alloy composition provides the material the necessary strength while  allowing the product to be easily shaped.

The material can be fabricated into complicated details for a multitude of shapes.  The appearance of RHEINZINK enhances the entire building, whether used for roofing, facade cladding, roof drainage, dormers, gable, balcony and chimney claddingRoof edges, awnings and wall copings can also exhibit a new brilliance with our material.

Sustainability low-to-no maintenance

Virtually all of the used titanium zinc can be recycled, an infinite amount of times, with low energy consumption and without producing any polluting residue.  The protective patina that develops on the surface of the zinc over time, gives zinc its incredibly long service life.  Numerous historical buildings worldwide can attest to the fact that zinc roofs over 100 years are completely intact with minimal maintenance performed.  Moreover, every RHEINZINK product we make today consists of 30% secondary material. Further information is available under sustainability.

Our material: RHEINZINK titanium zinc

“RHEINZINK” is a brand name for titanium zinc manufactured in line 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 technological material properties along with other factors and is also relevant for the colour of the RHEINZINK patina.

The raw material is smelted, cast as a material of uniform and certified quality and wound as a coil in one continuous operation.  These coils are used in further processing for manufacturing high-quality RHEINZINK roofing, roof drainage and facade.
