Zinc Qualities

Malleable

VMZINC provides the freedom to create architectural masterpieces which are difficult to realise with other construction materials. It is very malleable and can therefore meet virtually every architectural demand and provide solutions that less flexible materials cannot. Architects appreciate this versatility which allows them great freedom of expression in designing the roof and cladding of a building. Zinc resolves a large number of design issues and allows interesting treatments of corners and angles, creating an almost infinite variety of shapes: straight, curved, convex or concave.

Green Material

Zinc is a non-toxic, durable, recyclable and plentiful material. As an essential trace element, zinc is also vital to biological equilibrium and growth. Zinc used in the building industry is 100% recycled, putting it far ahead of many other materials which are just taking their first steps in recycling. Less energy is required to produce zinc than the other principal metals. The energy balance is even more favourable in recycled zinc. This excellent result clearly proves the contribution of VMZINC to sustainable development.

Top Performing Alloy

Composition Of Alloy

Our rolled zinc is alloyed with copper and titanium to produce a material with optimum mechanical and physical characteristics for building applications, particularly with regard to mechanical resistance and creep resistance.

It is composed of very high quality zinc Z1 (99,995% pure zinc), as defined by the EN 1179 standard, to which titanium and copper are added. Copper increases the mechanical resistance of the alloy, making it harder and stronger.
Titanium increases creep resistance permitting greater thermal expansion and contraction, of the material without causing metal fatigue.

EN988 Norm.

The European Standard EN 988 has been applied since 1997 in 18 European countries. This standard imposes very stringent specifications for the composition of rolled zinc and its physical, mechanical and dimensional characteristics, which make it an international reference.

Surface Aspects

Natural Zinc

When the zinc leaves the rolling mill it has a shiny, metallic surface appearance which changes over time as a natural, semi-mat, light grey patina is formed in contact with the atmosphere.              The natural light grey zinc has a textured, luminous quality that evokes the world of minerals. It enhances the appearance of the building from the very first day and for years to come.

Quartz Zinc

QUARTZ-ZINC is obtained by immersing Natural zinc by VMZINC in a solution which modifies the crystalline structure of the surface of the metal at a thickness of approximately one micron. This treatment is a durable chemical conversion of the surface structure of the metal. This is not a finish but a genuine, long-lasting treatment of the surface.

The velvet grey tones of QUARTZ-ZINC and its structural flexibility bring out the character of a building from the outset. Appreciated for refurbishment, its natural-looking colour blends well with other existing construction materials.

Pre-weathered QUARTZ-ZINC is produced using a surface treatment on Natural zinc by VMZINC. The pre-weathering treatment completed at the plant gradually evolves and coalesces over time with the naturally formed zinc patina. To ensure a consistent finish we recommend profiling and installing the components of a new project using a parent coil.

Anthra Zinc

The matt black look of ANTHRA-ZINC with the visible grain structure gives the material a velvet look, which is very much liked by Architects all over the world. Like QUARTZ-ZINC, it is obtain obtained by immersing Natural zinc by VMZINC in a solution which modifies the crystalline structure of the surface of the metal at a thickness of approximately one micron. This treatment is a durable chemical conversion of the surface structure of the metal.

This is not a finish but a genuine, long-lasting treatment of the surface.

Its name reflects the charcoal colour of slate, offering many combination with other material like timber, glass or natural concrete. ANTHRA-ZINC lends itself to highly structured architecture.

Pigmento Zinc

Zinc is known for its elegant shade of grey. But just imagine what a subtle shade of red, green or blue can contribute to your creation.

The PIGMENTO range is produced by adding mineral pigments to a QUARTZ-ZINC substrate. This substrate is preweathered zinc which from the beginning has an aspect and texture very close to the patina of natural zinc after a few months exposure to air.

The natural texture and colours of PIGMENTO, its nuances constantly changing with the light, reflect an organic and mineral universe. It inspires new ideas and blends perfectly with other materials.

4 colours are available :

  • Brown
  • Lichen Green
  • Autumn Red
  • Ash Blue

Azengar

AZENGAR is the 1st engraved zinc, an exclusive new aspect. Its uneven surface gives zinc a new image.

Rheinzink

Material

RHEINZINK is a trade name for titanium zinc, manufactured to DIN EN 988. Electrolytically refined zinc with a 99.995% degree of purity as defined by DIN EN 1179 serves as the basis for the alloy, which also includes small yet precise amounts of copper and titanium. The composition of the alloy is one of the factors determining the technological properties of the material – as well as the colour of the RHEINZINK patina.

The raw material is melted, cast and wound onto a steel sleeve in a single continuous operation. The quality of this material is uniform and flawless. These coils are then used for further processing as a universal source material to produce RHEINZINK’s high-quality roof drainage programme, pre-fabricated parts for roofing applications and facade cladding including the necessary building profiles.

RHEINZINK is available in four different Product Lines: RHEINZINK-PATINA, -PROTECT, -COLOR and -INTERIEUR.
