KME is one of the leading manufacturers of copper products in Europe, with a long history in the production of rolled copper for architectural applications. Their products are used on everything from listed building restorations to high-specification new builds, where copper’s appearance, longevity, and workability are valued.
Products and Finishes
KME produces copper in several forms and surface treatments under their TECU brand. Options include:
- TECU Classic — natural mill-finish copper that weathers from bright orange-brown to a stable mid-brown, then gradually to green patina over many years
- TECU Patina — factory-applied patina giving an aged green appearance from installation
- TECU Oxid — a brownish-red oxidised surface for a more immediate aged appearance
- TECU Gold — bright gilded tone for decorative applications
This range allows architects and contractors to specify the exact visual character they want at installation rather than relying entirely on natural weathering.
Why We Use KME
Copper is one of the most durable roofing materials available, with a lifespan that can exceed 100 years when correctly installed. KME copper products are manufactured to consistent standards and are well supported with technical guidance, making them a reliable choice for both standard and complex copper roofing projects.
We use KME copper on projects where the specification calls for high-quality copper — whether for a traditional standing seam roof, a contemporary cladding installation, or detailed restoration work.
Working with Copper
Copper roofing and cladding requires experience to install correctly, particularly at junctions, in valleys, and where the material meets other metals or materials. Bimetallic contact must be avoided, and rainwater run-off from copper surfaces needs to be managed carefully to prevent staining of adjacent materials.
Done well, copper is a beautiful and extraordinarily long-lasting material. We are happy to advise on whether copper is right for your project and which TECU finish would work best.
