Extrodinary corrosion resistance, good workability and the fact that it is aesthetically pleasing are some of the reasons why copper is especially suited as an economical material for roofing and cladding.

Material Data Sheet

KME Copper Sheets and Strips are made of CU-DHP.

The dimensional and mechanical tolerances ofTECU® products are in some cases considerably tighter than DIN EN 1172 regulations.
