Zinc has long been recognised as a dependable, corrosion-resistant, and visually appealing metal for roofing and cladding applications. When alloyed with titanium, zinc-titanium emerges as a prime choice for complex architectural projects, whether for new constructions or building renovations. Its exceptional strength, durability, and aesthetic appeal make it suitable for both roofs and façades, with a facade lifespan exceeding 150 years and roofs expected to last between 80 to 100 years.
One of the notable advantages of zinc-titanium is its natural ageing process, which varies based on environmental conditions. This metal can be successfully installed in diverse settings, including coastal areas, where traditional materials might struggle. Many examples of zinc roofing from over a century ago still exist, demonstrating minimal colour changes and requiring no special maintenance.
Zinc-titanium is available in a variety of sheet formats, such as widths of 1000 mm, 1200 mm, 1250 mm, and the exclusive 1340 mm offered by elZinc®. These sheets can be customised in length and thickness, ranging from 0.3 mm to 3.00 mm, with thicker materials often used for large-format façade panels. The ease of processing and remarkable malleability of zinc-titanium enable its application on various surfaces, from simple pitched roofs to intricately curved designs.
Architects can employ various techniques – such as split tiles, angular seaming, slats, and double seaming – to create distinctive textures and architectural identities with zinc-titanium laminates. This versatility allows for the shaping of architectural volumes using a single material or utilising different joining methods to emphasise specific building elements.
Zinc-titanium has a natural grey colour, enhanced by zinc carbonate patination that provides a warm hue without artificial colouring. This neutral tone seamlessly integrates with both modern and traditional materials, making it ideal for use in historical districts. The elZinc® brand offers a Rainbow (Organic Pigment Finish) range, featuring pre-weathered substrates with natural mineral pigments. This unique finish not only enhances aesthetic appeal with colours like maroon, blue, green, black, and red but also boasts exceptional corrosion resistance.
Sustainable development is one of elZinc’s priorities; it is part of the philosophy that leads them to implement innovative processes and products that respect the environment.
elZinc also provides the customised option of organic pigment matching to the nearest RAL shades, which gives an advantage to the architect to use zinc in the theme of the project.
For this reason, they have completed the Environmental Product Declaration (EPD) for elZinc Natural and the EPD for our entire range of elZinc Alkimi® pre-patinated products as part of the GlobalEPD program carried out by AENOR, an independent organisation of international prestige.
