Through our products, we are proud of the key role our group plays in the world we live in. The KME product range includes a complete assortment of semi-finished copper and copper alloy products designed for use in numerous applications. We keep an open dialogue with our customers, so that we can work together to develop resourceful, economical solutions for all kinds of copper applications, old and new.
	TECU® Classic Lasting value, durable yet changeable At first, the architecture grade material is bright red rolled copper. But what follows is an ever-changing spectacle of weather, light and the natural, lively language of the material: after installation on the building, TECU® Classic retains its typical bright red copper colouring for a period of time. Changes are gradual and not entirely predictable – just like the weather, which, in turn, is solely responsible for copper ’s continual changes. First, the sur face turns matt. Gradually, the material develops an oxide layer to protect it against the ef fects of weathering. This process brings with it striking colour variations through a wide range of brown tones, of fering varying nuances according to change of light and season. more >>
	TECU® Oxid As if touched by nature, in magnificent shades of brown Time-tested TECU® Classic quality copper with a completely different look: With TECU® Oxid, the initial bright, freshly-installed copper, and the gradual change of colour to shades of brown is simply bypassed. Natural changes on the building start immediately with a brown oxide layer. The process continues as with classical copper: Nature changes the surface through the effects of sun, rain, snow and wind, giving it an exciting life of its own – always unique, typical copper. TECU® Oxid copper sheets and strips are pre-oxidised on both sides in a patented industrial process that is gentle on the material. The oxide layer is not artificial but results naturally from the copper itself. more >>
	TECU® Patina 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. more >>
	TECU® Zinn Colourful grey: elegance and durability The elegant understatement of the exquisite matt grey surface harmonises excellently with many other building materials. And the connection between two exceptional metals combines the proverbial longevity of the carrier material with a metallic sur ace which, although not typical for copper, strikes just the right note. To manufacture TECU® Zinn, copper strips are specially tinned and surface-treated on both sides. The resulting sur face gradually takes on the distinctive matt grey colouring when exposed to weathering. more >>
	TECU® Brass A new kind of Brass - modern and expressive Copper alloys are exciting new highlights in façade materials – individual, extremely durable and exceptionally lively. As one of the best known copper materials, brass is now available as the new TECU® Brass, created by blending a special alloy of copper and zinc. The TECU® copper alloys develop their own unique character when exposed to the atmosphere. Weathering changes the original reddish golden colour of TECU® Brass; after the initial matting the surface takes on a greenish brown tone, which slowly turns greyish brown before evolving into a dark brown-anthracite colour. On sloping surfaces, a distinctive patina layer, typical of classical copper surfaces, develops. more >>
	TECU® Bronze Offering architecture new perspectives Bronze – an alloy of copper and tin and a synonym for metallic works of art. While artists have long made use of bronze, architects are now also able to make optimum use of the material – for more refinement in façade design. The original warm reddish-brown colour of TECU® Bronze develops in a distinctive manner through weathering. A brown-red surface oxidation with a brown-grey under tone is typical for this alloy; the material then gradually changes to dark brown anthracite throughout. The subsequent patina coating forms much more slowly than with pure copper. more >>
	TECU® Gold Copper and aluminium: a combination as good as gold. Gold doesn’t always have to glitter: TECU® Gold, a new copper-aluminium alloy for façade cladding, turns matt very soon after it has been installed on the building – gradually forming a striking warm golden surface which, although it doesn’t glitter, is still unmistakably reminiscent of the valuable precious metal. Façades clad with TECU® Gold convey a distinctive, pleasing and unique quality. In order to maintain this lasting impression, the surface changes very little over time. Further colour changes due to oxidation processes are hardly noticeable on the façade surfaces. more >>
