| TECU® Classic sheets and strips 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 to welding and soldering, and its purity levels according to DIN 1787 "Copper, Semi-Finished" amounts to at least 99.9%. Cu-DHP is outstandingly malleable, regardless of temperature or the direction of rolling. Both roofing and facade grades surpass the requirements of DIN EN 1172 in relation to tolerances and the most important technological values. This gives the processed surface an excellent visual appearance. |
