TITANZINC Pre-Weathered Titanium Zinc
Description
Zinc has been used as a roofing & cladding product for centuries. Traditionally it has a very strong presence in European countries where it’s durability and beauty has made it the roofing material of choice for many of Europe’s most classic buildings. Over time Zinc ages gracefully, developing an attractive grey carbonate patina which protects the surface against corrosion.
Modern technologies allow us to reproduce this natural process in a pre-weathered Zinc Titanium alloy, avoiding the need to wait years for the patina to develop. Modern Zinc is alloyed with small quantities of Titanium, Copper & Aluminium resulting in an extremely malleable material which gives designers scope to create complex architectural shapes for today’s buildings.
The Finish
TITANZINC has a smooth slightly grained surface finish which is the result of a chemical process that accelerates the formation of Zinc’s beautiful grey patina. This protective coating forms as a barrier between the elements and the base alloy below. One of the wonderful aspects of this protective layer is it’s ability to “self heal” if damaged. Armed with it’s protective patina from the start, pre-weathered Zinc effectively offers “peace of mind” to designers in a wide variety of environments. This attractive neutral finish blends effortlessly with a variety of commonly used building materials such as wood, glass and concrete.
Chemical Composition
99.995% pure Zinc with small quantities of Titanium & Copper added during the alloying process to aid formability.

Handling & Storage
TITANZINC products should always be kept dry and ventilated during storage and transportation. When stored on site, there should be a designated dry area for storage of TITANZINC products. Failure to protect TITANZINC in this way can lead to Zinc Hydroxide corrosion.
