„Pre-patinated copper for Roofing and Façade Cladding“

Green copper for immediate creative application – all natural, no limits.

Often the shortest path takes you directly to your goal. When the design demands the power and expressiveness of the patina green typical for copper, then it should be implemented just as required – without waiting for the gradual changes caused by natural weathering. The solution is TECU ® Patina – patinated copper for immediate use to satisfy the highest aesthetic demands in building design.

Using a specially developed industrial process, TECU ® copper sheets are patinated green on one side. This process causes an oxidised layer to form on the surface of the copper – a process similar to the natural patination that occurs over a long period of time when copper is exposed to atmospheric conditions. TECU ® Patina is always extremely varied, just as you would expect from a natural surface. The many different colour tones and shades eventually blend together, but only gradually. The unique developments occurring in TECU ® Patina are exciting – just as modern architecture should be.

Quality

“Beautiful? Absolutely stunning! For how long? Forever!”

TECU® Patina sheets are manufactured in state-of-the-art production facilities according to DIN EN 1172 and KME’s own strict guidelines. They are made of Cu-DHP – oxygen-free, phosphorus-deoxidised copper with limited residual phosphorus. Cu-DHP is well suited for welding and soldering; its degree of purity is at least 99.9 %, in accordance with DIN 1787 “Copper, Wrought Products”. Cu-DHP is outstandingly malleable, regardless of temperature and the direction of rolling. TECU® Patina surpasses the requirements of DIN EN 1172 with regard to tolerances and the most important technological values. This gives the processed surfaces their excellent visual appearance.

New: TECU ® Patina now with TSP surface protection
The temporary yet robust transparent layer ensures long-lasting protection. Processing is virtually dust-free. Traces of processing remain practically invisible on the material surface, and even after folding and bending, the patina layer remains in good condition. After installation, the surface develops in the completely natural manner characteristic of copper.

The surface

“The most massive structure comes across as virtually weightless.”

TECU® Patina has similar properties to those of natural patina right from the start. Its colouring continually changes on exposure to the elements. The lively colour spectrum so typical of copper develops over time. As a result of the manufacturing technology used, individual sheets can vary in colour from yellow green to blue green. Although these differences can be seen right after installation, they soon become less noticeable on exposure to the elements. Differences in the colour of natural surfaces like TECU® Patina are not a shortcoming, but rather a sign of quality. If TECU® Patina sheets are installed in interior areas, the colour assimilation requires a longer period, as the development of the patina is mainly influenced by humidity in the air. When installed in public buildings, TECU® Patina surfaces are better placed out of reach, or in constructional areas that are screened off from touch.*

Processing and Installation

„Wind and weather create their own kind of beauty.”

The physical appearance of TECU® Patina is influenced by the installation and the system applied. A combination of copper’s typical properties, such as malleability, high ultimate elongation, high melting point etc. lend TECU® Patina its special suitability for all metal-specific processing techniques from traditional seaming to modern cladding. TECU® Patina can be processed like bright rolled copper using standard techniques and machines. However, due to the special features of the Patina surface, a few important guidelines as to processing, material properties, transportation and storage should be
kept in mind.
